Product Description:

The AKM23D-EFC22-00 is a rotary actuator manufactured by Kollmorgen and assigned to the AKM Synchronous Servo Motors series. This model uses the standard customization level, so its mechanical dimensions and electrical data follow the regular production version without special options. It is intended for closed-loop automation axes where compact size and fast response are required to drive loads with accurate position, speed, and torque control. In these roles, the motor works with a servo drive to convert commanded current into controlled rotary movement during indexing, positioning, and speed regulation.

To secure a stopped shaft during power loss, the motor is fitted with a 24 V holding brake, allowing mechanical loads to remain stationary without external clamps. Power, signal, and ground conductors are routed through two SpeedTec Ready connectors, a keyed arrangement that simplifies connection and preserves ingress protection at the mating points. Rotor position is monitored by an integrated Comcoder, an incremental sensor that supplies 2048 lines/rev of base resolution to the drive. Because the encoder is configured as single-turn optical, the system reports position within one revolution but does not retain multi-turn counts. This feedback arrangement helps the paired drive correct position error quickly during acceleration and settling.

Feedback signals conform to the EPC 15T format, which supports compatibility with Kollmorgen AKD and other drives that read TTL-level differential outputs. The square 58 mm frame dimension sets the mounting envelope for compact servo axes, while a rotor length index of 3 adds active iron for higher continuous torque than shorter motors in the same frame. Electromagnetic behavior is set by winding designation D, so the voltage constant and rated speed match medium-voltage 240 VAC servo amplifiers. The motor layout is intended for compact installations where mounting space is limited but steady torque delivery is still required. Matching the feedback format and winding data to the drive helps maintain stable control behavior across the operating speed range.
