Compatible Mitsubishi Servo Drive Pairing
For the HG-KR43BK to perform at its best, pair it with a compatible Mitsubishi MR-J series servo amplifier:
- MR-J4-10A / MR-J4-10B — Standard position/speed/torque control
- MR-JE-10A — Cost-effective option for general automation
- MR-JE-10C — CC-Link IE Field Network variant
💡 Always verify the amplifier capacity (W rating) matches or exceeds the motor's rated power to avoid drive faults.

FAQ — Mitsubishi HG-KR43BK Servo Motor
Q1: Is the HG-KR43BK a genuine Mitsubishi product? Yes. Every unit we supply is a 100% original Mitsubishi Electric HG-KR43BK — factory sealed and inspected before dispatch. We do not sell aftermarket or remanufactured units.
Q2: What servo drives are compatible with the HG-KR43BK? The HG-KR43BK is compatible with Mitsubishi MR-J4 and MR-JE series servo amplifiers. Common pairings include the MR-J4-10A, MR-JE-10A, and MR-JE-10C. Always match the amplifier's rated capacity to the motor's 400W output.
Q3: What does the "BK" suffix mean in HG-KR43BK? The "BK" suffix indicates the motor is equipped with a built-in electromagnetic brake. This holds the load in position when the motor is de-energized — essential for vertical axis applications or safety-critical installations.
Q4: Does the HG-KR43BK require homing after a power cycle? No. The 20-bit absolute encoder retains position data even after power loss (when backed by a battery in the servo drive). This eliminates the need for a homing routine after every startup, saving cycle time on your machine.
Q5: Can I use this motor as a direct replacement for a failed HG-KR43BK? Yes — it is a direct, plug-in replacement for any existing HG-KR43BK installation. Ensure your servo drive firmware and parameter settings are configured for this specific motor model.
Q6: What is the difference between HG-KR43BK and HG-KR43K (without BK)? The standard HG-KR43K does not include a brake. The HG-KR43BK variant adds an integrated electromagnetic brake for load holding. If your original motor had a brake, always replace with the BK version.
Q7: How quickly can you ship, and is bulk pricing available? In-stock orders ship within 1–2 business days with worldwide express options available. For volume orders or ongoing procurement, please contact us via WhatsApp or the Enquiry button for competitive bulk pricing.
