Product Description:

The AKM44S-BSMN1-02 is a synchronous servo motor manufactured by Kollmorgen and delivered within the AKM Synchronous Servo Motors series. It converts drive current into controlled rotary motion for gantries, indexing tables, and light machine tools. By pairing compact stator geometry with rare-earth magnets, the motor provides the fast response and high torque density required in modern industrial automation cells. This makes it suitable for axes that need quick starts, controlled stops, and repeatable positioning during regular production cycles.

With a frame dimension of 84 mm, the motor fits compact machinery layouts while still providing the thermal mass needed for continuous torque. A NEMA-pattern flange simplifies mounting to standard gearheads or mechanical adapters. Position data are generated by a feedback device with 1024 lines/rev, and quadrature decoding in the drive supports accurate incremental moves. The integrated Comcoder combines optical sensing with commutation tracks so that phase information reaches the drive without additional Hall sensors. Because the unit uses a single-turn optical encoder only, absolute position is retained over one revolution and must be re-referenced after full rotations. The rotor is delivered without a holding brake, which reduces inertia and supports rapid acceleration.

The encoder uses the designation EPC 15T. Magnetic length is governed by rotor length index 4, which balances torque output with the existing frame. A special shaft profile can accept custom couplings or pulleys without secondary machining, and the motor uses a special winding optimized for application-specific voltage and current ranges. This combination supports installations that need nonstandard mechanical interfacing or electrical matching. The feedback arrangement and winding selection help the drive receive consistent motion data during axis operation.
