AKM21E-ANCNC-00

AKM21E-ANCNC-00 is a Kollmorgen motor in the AKM Synchronous Servo Motors series. It has a standard customization level, a 58 mm frame dimension, and rotor length index 1. The IEC flange has accuracy class N for mounting alignment, while the smooth shaft provides a plain mechanical coupling surface. Two SpeedTec-ready connectors provide the motor and feedback connections, and the motor is supplied without a brake.

The E-designation winding produces a continuous stall torque of 0.5 N-m at 3.11 Arms and a peak stall torque of 1.49 N-m at 12.4 Arms. Its torque constant is 0.16 N-m/Arms, relating supplied current to generated torque, and its back EMF constant is 10.2 Vrms/kRPM. The winding has 3.42 ohms of DC resistance at 25ºC and 5.2 mH of inductance. Rotor inertia is 0.0000107 kg-m².

With a 120 VAC supply, the motor has a rated speed of 7,000 RPM, a maximum speed of 8,000 RPM, and a rated torque of 0.41 N-m. With a 75 VDC supply, it operates at a rated speed of 2,000 RPM and produces 0.48 N-m of rated torque. The SFD feedback system provides motor position feedback through four signal lines. It uses single-turn inductive feedback and has a feedback type associated with sizes 10, 15, and 21.
