Product Description:

The AKM42E-EKMNR-00 is a brushless AC servo motor produced by Kollmorgen as part of the AKM Synchronous Servo Motors series. Designed for closed-loop positioning and velocity control, the unit translates drive commands into precise rotary motion in automated machinery such as indexing tables, Cartesian gantries, and packaging axes. Its permanent-magnet rotor and low-loss stator windings help achieve repeatable cycle times while keeping thermal rise within typical factory limits. With a continuous duty rating matched to mid-frame automation layouts, the motor fits on 85 mm IEC mounts without added adapter plates.

This model is supplied without a brake, so any load-holding function must be provided by the drive or an external mechanical lock. Position information is captured by a resolver, and the analog sinusoidal feedback withstands high vibration and temperature while still providing rotor angle information. The feedback stack is wound for 2 poles, which yields one electrical cycle per mechanical revolution and simplifies commutation. A frame dimension of 84 mm gives the motor a square mounting face that matches the AKM42 format. The shaft is machined with an open keyway, enabling torque-safe coupling to pulleys or gears without additional clamping features.

The active steel package follows an index 2 rotor length, balancing inertia against continuous torque for mid-range power demands. The coils use winding e, which aligns electrical resistance and inductance with 230 V servo amplifiers and keeps current within drive ratings. Feedback hardware is classified as Size 10/15/21, a compact resolver form factor that fits completely inside the housing and tolerates typical factory contaminants. The motor is supplied at the standard level of customization, so its seals, connectors, and paint follow the standard product configuration.
