Product Description:

The AKM41H-BSMN1-02 is a brushless synchronous servo motor produced by Kollmorgen within the AKM Synchronous Servo Motors series. Designed for closed-loop industrial positioning tasks, the unit converts drive current into precise rotary motion for packaging equipment, assembly stations, and automated inspection axes. Its permanent-magnet construction and low electrical time constants support fast current loops that modern digital drives require. This helps the motor respond quickly during repeated starts, stops, and direction changes in automated machinery.

Its integrated position transducer delivers 1024 lines/rev of optical resolution, allowing the drive to interpolate fine increments for tight velocity and position loops. Kollmorgen uses a Comcoder feedback system, combining incremental and commutation tracks in one sensor so the controller can power up with absolute rotor angle knowledge. That sensor is configured for single-turn optical operation, meaning it reports shaft angle within one mechanical revolution without multi-turn counting. Identification code EPC 15T indicates the electrical interface and wiring scheme used with compatible AKD amplifiers. The motor uses an 84 mm square frame, which keeps the housing compact where mounting space is limited. This feedback arrangement also supports steady low-speed control and accurate positioning during short cycle moves.

The mounting flange follows the NEMA template, simplifying alignment with gearboxes and direct-drive brackets already cut to that standard. For applications that do not require power-off holding, the motor is supplied without a brake, which reduces inertia and removes a brake assembly from the motor package. Coil style H indicates a winding intended for intermediate bus voltages while still supporting high peak torque. A rotor length index of 1 indicates the shortest magnetic stack in this frame, which supports quick acceleration and lower rotating mass. The shaft is machined to a special profile so couplings or pulleys can seat directly without custom adapters. This layout is useful on compact indexing axes and other motion systems that need responsive speed changes in a limited installation space.
