Product Details:

KOLLMORGEN AKM42E-EKGNR-01 is an 84mm frame permanent magnet synchronous servo motor from Kollmorgen AKM series, equipped with resolver feedback and keyed shaft configuration. The suffix 01 stands for special shaft and sealing customization, which is optimized for workshop environments filled with oil mist and fine coolant particles. It maintains stable medium torque output and excellent overload capacity, designed for cyclic feed axes exposed to lubricant splashes and continuous mechanical vibration.

This servo motor adopts contactless inductive resolver as position feedback. Without fragile optical components, the resolver can withstand intense shock, wide temperature variation and oil contamination, delivering reliable rotor angle and speed signals to matched Kollmorgen AKD servo drives for closed-loop motion control. Separate rotatable M23 connectors for power and feedback circuits isolate power noise from position signals and reduce electromagnetic interference inside densely arranged electrical cabinets.

This variant does not come with built-in holding brake, so it is suitable for horizontal feed axes and continuous transfer structures where static shaft locking is not required. The keyway shaft provides firm torque transmission with reducers and couplings and prevents slippage under frequent load switching. The stator winding uses Class F insulation material and integrates PTC thermal sensor for real-time overheat protection. The motor housing reaches IP54 protection grade, and the customized sealing structure of this 01 version further blocks oil mist from entering the bearing chamber to extend service life. Optimized low cogging magnetic circuit suppresses torque ripple, ensuring smooth rotation at low speed and rated speed.

It supports torque control, speed control and position control modes, and all motion parameters can be tuned conveniently via Kollmorgen drive software. Standard IEC mounting dimensions support direct replacement of legacy AKM motors, simplifying equipment renovation and spare part replacement work. Every finished motor passes strict factory validation before shipment, including resolver signal calibration, oil mist tightness inspection, heavy load cycling test, insulation resistance check and vibration endurance test to guarantee stable performance in multi-shift harsh production lines.

It is widely deployed on metal transfer machinery, heavy forging auxiliary lines, textile spinning equipment, lubricated conveyor systems and heavy-duty forming machines. Typical application axes include progressive feed slides, material pulling modules, continuous transfer drives and reciprocating pushing units. Automation integrators select this resolver keyed-shaft variant for its outstanding oil and vibration resistance, reliable torque transmission and seamless compatibility with Kollmorgen AKD motion control ecosystem.
