The Mitsubishi HG-KR13D is a low-inertia, small-capacity AC servo motor from the MELSERVO-J4 series, rated at 100W (0.1kW) output with 200VAC class 3-phase supply. It delivers 0.32 Nm rated torque at 3000 rpm rated speed, with a 22-bit high-resolution absolute encoder providing 4,194,304 pulses per revolution for ultra-precise positioning. The D suffix indicates a D-cut shaft with flat for simple coupling attachment. Being low inertia, the HG-KR13D excels in applications requiring rapid acceleration, deceleration, and high-frequency start-stop cycles. Its compact 40mm flange size makes it ideal for small-form-factor machines. Typical applications include semiconductor pick-and-place, small robotic arms, labeling machines, medical device automation, dispensing systems, electronic component placement, and precision assembly equipment where space and speed are critical.
**Q: What amplifier is compatible with the HG-KR13D?**
A: The HG-KR13D is designed for Mitsubishi MR-J4 series servo amplifiers, specifically the MR-J4-10A (100W) or MR-J4-10B models. It connects via the standard MELSERVO-J4 motor power/encoder cable set.
**Q: What does HG-KR mean in the model code?**
A: HG = Rotary servo motor, KR = Low inertia, small capacity series. 13 = rated output code (100W). D = D-cut shaft with flat. This is part of the MELSERVO-J4 generation of Mitsubishi servo motors.
**Q: What is the advantage of a 22-bit encoder?**
A: The 22-bit absolute encoder provides 4,194,304 pulses per revolution, enabling sub-micron positioning accuracy when used with precision ball screws or linear actuators. Absolute encoding also means the position is retained even after power-off, eliminating the need for homing routines.
**Q: Is this motor suitable for vertical axis applications?**
A: This specific model (HG-KR13D) does not include a brake. For vertical axis applications requiring a holding brake, use the HG-KR13BD or HG-KR13BJ variant which includes a built-in electromagnetic brake.
**Q: What is the maximum cable length between motor and amplifier?**
A: Mitsubishi recommends motor power cable length up to 30m for standard applications, and encoder cable length up to 30m. For longer distances, consult the amplifier manual for derating guidelines.
