Product Description:

The AKM21G-BSMN1-02 is manufactured by Kollmorgen as part of the AKM Synchronous Servo Motors series. Deployed with matching drives, the unit functions as a precision rotary actuator in automated assembly cells, pick-and-place stations, and packaging machinery. By converting commanded current into controlled torque and velocity, it supports repeatable positioning cycles that are critical for coordinated multi-axis motion. Its compact housing allows the motor to fit into tight machine spaces while maintaining the dynamic response expected from modern servo systems.

The motor’s integrated feedback package provides 1024 lines/rev of incremental position data, giving control loops fine angular resolution during low-speed moves and accurate detection of standstill drift. A Comcoder sensing element combines commutation tracks with incremental channels to reduce wiring complexity and simplify alignment. The signal format, designated EPC 15T, matches compatible Kollmorgen drives, so parameter scaling is not required. Mechanical mounting follows the NEMA flange pattern for direct installation on compatible machine interfaces. The overall diameter is 58 mm, allowing the motor to fit into narrow machine frames while still accommodating the internal rotor and sensor stack. The unit is supplied without a brake, so external clamping or continuous servo holding torque must secure vertical loads.

Position feedback is implemented as a single-turn optical encoder, so position information is available across one revolution and homing routines remain brief. The rotor length is identified by index 1, which is the shortest active stack in the AKM21 frame and favors low mass with moderate continuous torque density. The stainless-steel output end includes a special shaft configuration for custom couplings or gearheads that cannot accept standard keyways. Electromagnetic characteristics stem from winding class G, which sets the voltage and current relationship used with the matching drive while keeping thermal rise within normal limits.
