Product Description:

The AKM51H-BKC2EJ01 is a rotary servo motor produced by Kollmorgen and included in the AKM Synchronous Servo Motors series. It is intended for closed-loop motion axes in industrial automation where fast response and position accuracy are required. When coupled with a matched digital drive, the motor converts commanded current into proportional torque, allowing tight speed and position control for packaging machinery, pick-and-place gantries, and assembly stations. This operating role suits equipment that depends on repeatable starts, stops, and synchronized axis motion during continuous production.

This model is equipped with a 24 V holding brake, so the shaft can remain locked when power is removed and maintain load position on vertical or suspended axes. Electrical and feedback connections are routed through 2 SpeedTec Ready connectors, which permit keyed push-turn mating and help keep cable routing compact around the motor body. A NEMA flange provides a standardized bolt pattern that aligns with common gearheads and machine frames, while the 108 mm frame dimension sets the outside diameter and influences available torque. Inside the stator, the coils follow the winding designation H, matching the voltage constant and resistance used by compatible Kollmorgen drives.

A factory-installed shaft seal establishes an oil and dust barrier at the output end, supporting better sealing when a sealed gearbox is attached. The slender rotor stack, identified as rotor length index 1, gives the motor moderate inertia that balances acceleration capability with smooth running during repeated indexing. Power is transmitted through an open keyway on the output shaft, so torque can be transferred directly to pulleys or couplings without additional machining. This arrangement supports applications that need positive torque transfer while still fitting within compact machine layouts.
