Product Description

Sanyo Denki P50B07050DCL60 — SANMOTION BL Super P5 AC Servo Motor | 500W | 200V | 3000 rpm | 76mm Flange | 90V DC Brake | New In Stock

Replacing a servo motor on a Kawasaki robot arm doesn't leave room for approximation. The replacement has to match exactly — same flange so it bolts straight in, same electrical interface so the drive accepts it without rework, same encoder protocol so the feedback loop behaves identically. The P50B07050DCL60 is a Sanyo Denki BL Super P5 motor built to Kawasaki's specific connector and cable specification. The "60" suffix distinguishes it from standard commercial variants like the DCLBJ — same electrical and mechanical specification, different output connector geometry. For anyone servicing a Kawasaki robot, the DCL60 is the designation to specify.

Outside robot maintenance, this motor stands on its own as a capable 500W brushless AC servo motor. Machine tool auxiliary axes, indexing tables, packaging machinery, and general automation positioning systems are all straightforward applications for the 76mm frame, 200V, 3,000 rpm rating this motor delivers.

Model Number Decoded — P50B07050DCL60

Every character in the Sanyo Denki model string carries a specific meaning. Reading them in sequence removes any ambiguity about what this motor is and what options are built in.

P5 — SANMOTION BL Super P5 product family. Sanyo Denki's P5 brushless AC servo motor series covers 30W to 1,000W rated output, with speeds from 3,000 min⁻¹ rated to 4,500 min⁻¹ maximum. The "BL" stands for brushless — no carbon brushes, no commutator, no brush-related maintenance. The permanent magnet rotor construction provides the high torque-to-inertia ratio that modern servo applications demand.

0B — Standard square flange mount configuration.

07 — 76mm flange size. The frame dimension code: 05 = 54mm, 07 = 76mm, 08 = 86mm. The 76mm body sits between the compact 54mm class and the larger 86mm frame, suitable for mid-range torque demands where a smaller motor would run near its thermal ceiling.

050 — 500W rated output. Three digits representing rated power in watts. Within the P50B07 frame, the range runs from 030 (300W) through 050 (500W) — this is the highest output available in the 76mm body.

D — 200V AC supply voltage. The standard for industrial servo drives in most manufacturing environments globally.

C — 90V DC electromagnetic holding brake, factory-integrated. The brake engages (locks the shaft) when de-energized and releases when 90V DC is applied — a fail-safe configuration that prevents axis movement during power loss or emergency stop.

L — Wire-saving incremental encoder. Reduced conductor count compared to full-pin encoder variants, simplifying multi-axis cable routing. Outputs standard ABZ incremental quadrature signals for position and velocity feedback.

60 — Kawasaki-specific output connector and cable variant. This suffix identifies the particular connector geometry and pinout that mates with Kawasaki's robot cable harness directly, without adaptation work.

Brushless Permanent Magnet Construction — What It Means in Practice

The "BL" designation is worth understanding beyond marketing language. Traditional DC servo motors use carbon brushes riding against a rotating commutator ring to transfer current into the spinning armature windings. Those brushes wear down. They generate carbon dust. They require periodic inspection and eventually replacement — and if maintenance is deferred, they damage the commutator surface and cause the motor to fail prematurely. In high-cycle environments or applications where the motor runs for extended hours daily, brush life can be as short as a few thousand hours.

The P50B07050DCL60 has none of this. The permanent magnets are on the rotor; the copper windings are fixed in the stator. Commutation is handled electronically by the servo drive, which sequences three-phase currents through the stator windings based on the encoder's real-time position feedback. There is nothing rubbing against anything. The only conventional wear items in this motor are the shaft bearings — and a properly installed motor running within its rated radial and axial load limits will run those bearings for tens of thousands of hours without intervention.

The rotor inertia figure of 0.74 × 10⁻⁴ kg·m² is a meaningful performance indicator. A lower rotor inertia means the motor can accelerate and decelerate its own shaft quickly without the drive needing to command large current pulses. For applications with short positioning moves at high cycle rates — pick-and-place mechanisms, tool indexing, wrist axis positioning on a robot — low rotor inertia directly translates to shorter move times and higher throughput. The rated power rate of 22.1 kW/s quantifies this dynamic response capability.

The 90V DC Holding Brake — Mechanics and Behavior

The holding brake built into this motor is an electromagnetic spring-applied device, entirely separate from the servo drive's current-based torque control. When 90V DC is applied to the brake coil, electromagnetic force compresses the spring and lifts the friction pad away from the disc — the shaft turns freely. When that 90V supply is removed, the spring pushes the pad against the disc and locks the shaft. Holding torque is rated at 0.98 N·m.

This fail-safe behavior is deliberate. In a vertical axis application — a robot joint resisting gravity, a machine tool Z-axis, a lifting mechanism — a brake that releases on power application and engages on power loss ensures the load stays put during any unplanned power interruption. It's also the behavior required during robot teach pendant operations, where the operator moves the arm manually and needs to know the joints won't drift when the enable button is released.

One thing worth being clear about: this is a holding brake, not a dynamic brake. It's designed to hold a stationary shaft against static loads. Using it to stop a moving axis — deliberately engaging the brake while the motor is running at speed — causes rapid friction disc wear and will eventually damage the brake mechanism. Controlled stopping is the servo drive's job; the brake's job is to hold position once the drive has brought the axis to rest.

Kawasaki Robot Applications

Sanyo Denki has a long supply relationship with Kawasaki Robotics, and the P50B07050DCL-series motor appears across multiple Kawasaki robot models as a joint axis drive. The "60" suffix in the model number is the key Kawasaki-specific element. It designates the output connector configuration that directly mates with Kawasaki's motor cable harness — no connector adapter, no field pin-out rework needed.

The 500W output at 76mm frame size corresponds to the torque and speed requirements of mid-range joint positions in Kawasaki's small-to-medium payload robot arms. Different joints in the same robot arm use different power ratings depending on the load each joint sees — the shoulder joint carrying the full arm weight needs a much larger motor than a wrist axis positioning a tool. The P50B07050DCL60 sits in the range appropriate for wrist or auxiliary axis duties on many Kawasaki designs.

For robot maintenance, always confirm the Kawasaki internal part number from the robot's parts manual and verify it cross-references to P50B07050DCL60 before ordering. Kawasaki sometimes uses minor variant designations (such as DCL60S with an added shaft seal) for specific robot models or environmental options.

Choosing Within the BL Super P5 Family

When comparing models or confirming you have the right specification:

Model	Output	Frame	Brake	Connector
P50B07030DCL60	300W	76mm	90V DC	Kawasaki "60"
P50B07050DCL60	500W	76mm	90V DC	Kawasaki "60"
P50B07050DCLBJ	500W	76mm	90V DC	Standard catalog
P50B07050DCL60S	500W	76mm	90V DC	Kawasaki + shaft seal
P50B08075DCL	750W	86mm	90V DC	Varies by suffix
P50B08100DCL	1000W	86mm	90V DC	Varies by suffix

The DCL60 and DCLBJ share identical electrical and mechanical specifications. The difference is purely connector configuration. For Kawasaki systems, DCL60 is correct. For other servo drive platforms, the DCLBJ or an equivalent commercial suffix is more practical since it avoids Kawasaki-specific connector geometry.

❓ FAQ — Sanyo Denki P50B07050DCL60

Q1: What does "500W" actually mean in terms of shaft torque and speed, and how does the "050" code relate?

The "050" in the model number directly represents 500W of rated mechanical output. At the rated operating point — 3,000 min⁻¹ shaft speed with 200V AC supply — the motor delivers roughly 1.59 N·m of torque at the shaft. You can verify this from the torque constant: at 3.0 Arms rated current and a torque constant of 0.481 N·m/Arms, rated torque is approximately 1.44 N·m, which at 3,000 rpm works out to around 450–500W depending on efficiency. The motor can be operated above rated current for short duty cycles, and the maximum speed of 4,500 min⁻¹ is available at reduced load. For continuous duty sizing, use the 500W / 3.0 Arms / 3,000 rpm rated conditions as the design basis.

Q2: What is the practical difference between the P50B07050DCL60 and the P50B07050DCLBJ — can they substitute for each other?

Electrically and mechanically, these two motors are identical. Same 500W rated output, same 76mm flange dimensions, same 16mm shaft diameter, same 200V AC supply, same 3,000 rpm rated speed and 4,500 rpm maximum, same 90V DC brake with 0.98 N·m holding torque, same wire-saving incremental encoder, and same 2.1 kg mass. The sole difference is the output connector configuration at the end of the motor cable. The "60" suffix identifies the Kawasaki-specific connector geometry; the "BJ" suffix identifies the standard commercial connector configuration. If you are replacing a motor in a Kawasaki robot, you need the DCL60 — it plugs directly into Kawasaki's cable harness. If you are using the motor with a non-Kawasaki servo drive, you would typically prefer the DCLBJ or an equivalent commercial suffix and make your own cable to match the drive's input connector.

Q3: The 90V DC brake needs an external power supply — how is this handled in a typical installation?

The motor contains the brake mechanism (coil, spring, friction disc) but not a power supply. The 90V DC must come from the machine's control cabinet. In a Kawasaki robot, the controller itself provides 90V DC brake release voltage as part of its standard axis control circuitry — the brake connections are part of the motor cable harness. In a standalone servo drive installation, options include a dedicated 90V DC power supply module, a brake driver circuit within the servo amplifier (many modern amplifiers include a 24V or 90V brake output), or an external relay-switched power supply. The critical wiring requirement is that the brake release circuit must be interlocked with the servo drive's enable signal: brake releases when drive enables, brake engages when drive is disabled. Running the drive enabled while the brake is accidentally engaged — or releasing the brake while the drive is faulted on a vertical axis — will cause problems in either direction.

Q4: Can this motor be driven by a servo drive from another manufacturer, such as Yaskawa, Mitsubishi, or Panasonic?

Yes, with two conditions to manage. First, electrical compatibility: the motor's 200V AC, 500W, three-phase brushless construction is compatible with any servo drive that supports a 200V brushless servo motor of equivalent current rating. The 3.0 Arms rated current is modest, so most drives in the 0.5–1.5 kW class can drive it. Second, encoder compatibility: the wire-saving incremental encoder outputs standard ABZ quadrature signals, which most drives accept, but the specific connector and signal levels must be verified and a suitable encoder cable fabricated to match the drive's input connector. The "60" Kawasaki connector on the motor means the encoder and power cables use Kawasaki's physical connector — straightforward to work around with a custom cable, but it does require some fabrication effort compared to using a commercially available motor-to-drive cable assembly.

Q5: What kind of industrial robots and machines commonly use the P50B07050DCL60?

Kawasaki industrial robot arms are the primary application this particular variant was designed for, with the "60" suffix specifically identifying the Kawasaki harness interface. Within Kawasaki's lineup, motors in the 500W / 76mm class serve mid-range joint positions — often wrist axes or smaller payload arm designs where 500W covers the torque and speed envelope required. Beyond Kawasaki robots, any automation system calling for a 500W brushless servo motor in a 76mm package will fit the motor's specifications: conveyor indexing drives, CNC rotary tables, packaging machine axes, pick-and-place mechanisms, and similar industrial motion applications where compact geometry and moderate power are the design parameters.

Q6: How long will the motor run before it needs service, and what actually wears out?

The brushless construction eliminates brush wear entirely — the most common failure mode in conventional DC servo motors is gone. What remains are: shaft bearings, which in a correctly loaded installation (radial and axial loads within rated values) can run for 20,000–30,000 hours or more before requiring replacement; the brake friction disc, which is a wear item if the brake is used frequently for controlled stops during motion (it is not designed for this, but if it happens regularly it accelerates wear); and the encoder, which is a solid-state device with very long life in normal operating conditions. In practice, the most common service events on brushless servo motors are bearing replacement after extended service, brake disc inspection and replacement on motors that have accumulated many brake engagement cycles, and connector inspection on motors in environments with vibration or contamination. The motor body, windings, and permanent magnets are essentially indefinite-life components under normal operating conditions.

Q7: Is a matching servo drive available, and what Sanyo Denki amplifier is compatible with the P50B07050DCL60?

Sanyo Denki produces the SANMOTION servo amplifier series designed to pair with their P5 and R-series motors. The specific amplifier model depends on the control interface required (pulse-direction, analog velocity, or network-based), the axis count, and the power rating needed for the 500W motor. The wire-saving incremental encoder on the DCL60 is directly compatible with Sanyo Denki's amplifiers that support the L-type encoder connection. That said, since this motor is often used in Kawasaki robot systems, the servo drive in that context is Kawasaki's own motion controller — a dedicated Sanyo Denki amplifier is not involved. For standalone machine building applications using this motor outside a robot context, the appropriate amplifier selection should be confirmed against the Sanyo Denki SANMOTION amplifier selection guide, which cross-references motor catalog numbers to compatible amplifier models and connector configurations.
