Product Description:

The AKM42E-ANM2EH01 belongs to the AKM Synchronous Servo Motors series from Kollmorgen. It is a brushless AC servo motor intended to deliver closed-loop torque and speed for coordinated industrial axes such as pick-and-place arms, form-fill-seal stations, and indexing conveyors. A rare-earth rotor and resolver feedback are packaged inside a compact housing so the motor can be mounted close to the driven load, which reduces coupling compliance and supports accurate multi-axis motion. The compact layout also helps keep rotating mass close to the axis, supporting responsive speed changes during synchronized operation.

The motor incorporates a 24 V holding brake that clamps the shaft during power-off events and helps prevent vertical loads from drifting. The housing uses a frame dimension of 84 mm, which sets the motor envelope and matches standardized gearhead interfaces. Positioning repeatability is aided by an IEC flange with accuracy N, which centers the stator within mating pilot diameters. Inertia is tuned through a rotor length index 2, which balances acceleration response with load-matching capability. For environmental protection, the unit ships with a shaft seal, which limits dust or fluid ingress at the output journal when the motor is mounted in washdown or oil-mist areas.

The output end uses a smooth shaft, allowing couplings or pulleys to be press-fit without keyways that could concentrate stress. This arrangement supports friction-fit transmission elements in compact machine assemblies where low backlash is important. Coil impedance and back EMF are established by the winding designation e, making the motor compatible with medium-voltage AKD and S700 drives. The motor uses matched cables and feedback options from the AKM platform for integrated operation with compatible servo systems. Thermal derating and commutation settings must match the drive so the motor can sustain continuous duty while maintaining the requested velocity and position tolerances.
