Product Description:

The AKM41S-EKM2EF02 servo unit is manufactured by Kollmorgen as part of the AKM Synchronous Servo Motors series. This brushless AC motor is intended for use with digital drives in industrial automation, converting commanded current into tightly regulated torque and velocity for indexing tables, gantry axes, and articulated tooling. Its medium frame size balances continuous torque capacity with a compact envelope, allowing installation in packaging, electronics assembly, and light machine-tool stations where cycle time and positional accuracy are critical. The motor is suited to applications that require repeatable starts, stops, and speed changes without adding a large mechanical footprint to the axis.

The integrated commutating encoder provides 2000 lines/rev of resolution, enabling sinusoidal commutation by the controller and supporting smooth low-speed operation. A frame dimension of 84 mm sets the square mounting face and aligns with standard IEC flange patterns. The magnetic circuit uses 10 poles, which increases torque density while keeping electrical frequency within typical inverter bandwidths. For load holding during power loss, the motor includes a 24 V holding brake that engages automatically when drive power is removed. Electrical terminations are routed through dual Molex connectors, separating power and feedback to simplify cable routing and reduce wiring mistakes around the motor.

Mechanical power is delivered through an open keyway shaft connection. The output shaft diameter is 19 mm and its working length is 40 mm, dimensions that match standard metric drive hardware. Overtemperature protection relies on an internal PTC sensor so the drive can react before winding temperatures rise too far. A fixed 0.5 m lead between the motor housing and the connectors simplifies strain-relief planning, and the IP20 connector shroud suits cabinets that already provide higher ingress protection. The special winding designation and rotor length index 1 adjust back-EMF and torque constants so the motor can support higher speed operation without changing its mechanical footprint.
