Product details

Mitsubishi HG-KR73 servo motor from the MELSERVO-J4 series delivers 0.75 kW rated output with IP65 enclosure. This standard model does not include an oil seal; order the HG-KR_J variant for that. It's rated for 2.4 N·m continuous torque and hits 8.4 N·m peak, spins 3000 rpm rated, 6000 rpm max, and handles loads up to 17 times the rotor inertia without complaint. The 22-bit absolute encoder tells the drive exactly where the shaft is on power-up – no homing needed on a typical machine.

Install indoors at ≤2000 m elevation and 0–40 °C non-condensing; vibration resistance is 49 m/s² on X/Y axes. Compatible servo amplifiers support CC-Link IE, SSCNET/H, or general-purpose interface.

Frequently asked questions

Does the HG-KR73 have an oil seal?

No, this standard model does not. If you need an oil seal, order the HG-KR_J variant.

What is the peak torque of the HG-KR73?

Maximum torque is 8.4 N·m, available for short-term acceleration or deceleration.

What encoder does the HG-KR73 use?

A 22-bit absolute/incremental encoder, giving 4,194,304 pulses per revolution. It keeps position after power loss.
