AKM44J-EKCNR-01

AKM44J-EKCNR-01 is a Kollmorgen motor in the AKM Synchronous Servo Motors series. It has an 84 mm frame dimension, a rotor length index of 4, and a J winding designation. The 10-pole motor produces 6.00 Nm of standstill torque at 8.80 A and reaches a peak torque of 20.4 Nm at a peak current of 35.2 A. Its rotor inertia is 2.7 kgcm², which describes the rotor’s resistance to changes in rotational speed. The thermal time constant is 24 minutes.

The winding has an inductance of 3.8 mH and a resistance of 0.94 ohm, which affect current response and electrical losses. At 3,000 rpm, the motor supports an axial load of 180 N and a radial load of 450 N. The shaft has an open keyway for keyed mechanical coupling. A shaft seal is included, and the shaft bushing carries an IP67 rating for protection against dust and temporary water immersion. The motor does not include a brake.

A single-turn inductive resolver provides rotor-position feedback without tracking multiple revolutions. The resolver has a two-pole feedback resolution and supports size 10, 15, or 21 feedback configurations. Two SpeedTec-ready connectors provide the motor and feedback connections.
