Product details

The Mitsubishi HG-KN43 is a 400 W AC servomotor from the MELSERVO-JE series, delivering 1.3 Nm rated torque and 3.8 Nm peak torque at 3000 rpm rated speed, with a maximum speed of 5000 rpm. The 17-bit absolute encoder (131072 p/rev) provides position feedback resolution suitable for general-purpose motion control on indexing tables, conveyors, and pick-and-place axes. IP65 protection means the motor body withstands washdown and particulate ingress — no additional enclosure needed for food-grade or wet-area mounting, though the connector and cable entry still require proper sealing per the installation manual. The keyway shaft (not a keyless clamp) requires a matching key and set-screw torque per the drawing. No brake is fitted — the load must hold position through the drive's holding brake or an external mechanical brake. For vertical-axis applications or power-off holding, specify the braked variant or add a separate brake resistor and holding circuit.

Powered from a 200 V AC three-phase supply. The MELSERVO-JE drive (sold separately) handles the commutation and encoder feedback; the motor cable set includes the power and encoder lines. Verify the drive firmware revision supports the 17-bit encoder protocol — older JE-series drives may require a firmware update.

Frequently asked questions

What are the key torque and speed ratings?

Rated torque is 1.3 Nm, maximum torque is 3.8 Nm. Rated speed is 3000 rpm, maximum speed is 5000 rpm. Rated capacity is 400 W.

Does this servomotor include a brake?

No. The brake field is listed as NO — no holding brake is fitted. For vertical loads or power-off holding, use the braked variant or an external brake.

What encoder does the HG-KN43 use?

A 17-bit absolute encoder with 131072 pulses per revolution. This provides position feedback for closed-loop control through the MELSERVO-JE drive.

What is the protection class?

IP65, meaning the motor body is dust-tight and protected against low-pressure water jets from any direction. Suitable for washdown environments provided the connector and cable entry are properly sealed.
