Product Description:

The AKM42J-GCC2R-01 servo motor is produced by Kollmorgen as part of the AKM Synchronous Servo Motors series. This brushless unit is intended for closed-loop position, speed, and torque control in automated machinery such as pick-and-place gantries, indexing tables, and packaging stations. By incorporating a resolver for feedback and an integrated brake, the motor gives the connected drive controller what it needs to hold or accelerate loads precisely, making it a flexible component for multi-axis industrial automation platforms.

This motor includes a 24 V holding brake that locks the rotor whenever the amplifier disables torque, preventing gravitational run-down on vertical axes. Electrical power, feedback, and brake wiring are routed through two SpeedTec Ready connectors, which use a quarter-turn latch for faster connection and removal. A shaft seal sits behind the front bearing to block coolant or grease ingress and to support the published protection rating. Rotor position is measured by a 2-pole resolver; this single-turn inductive sensor in size 10/15/21 housing supplies sine-cosine signals that the drive interpolates for high-resolution commutation. Because the sensor delivers only one electrical cycle per mechanical revolution, homing routines remain straightforward and absolute multi-turn memory is unnecessary.

The mounting face follows alternative flange variant G, letting the motor replace earlier AKM units without altering the machine housing. Overall diameter and bolt circle correspond to the 84 mm frame, while the magnetic stack is extended to rotor length index 2 to reach the desired torque density. Output torque is delivered through a keyway shaft that accepts standard couplings and pulleys. To match mid-range DC bus levels, the stator uses winding code J, which supports consistent torque production across the intended speed band.
