Product Description:

The AKM74Q-ANHNR-00 is a synchronous servo motor produced by Kollmorgen and part of the AKM Synchronous Servo Motors series. Designed for closed-loop motion axes in automated machinery, the motor converts drive current into controlled torque and speed so that positioning tasks remain repeatable under varying loads. This type of motor is commonly used where the drive must regulate acceleration, holding behavior, and speed changes with consistent response. Its modular platform allows matching frame size, winding, and feedback options to compatible servo amplifiers without extensive customization.

The motor has a frame diameter of 188 mm, which suits installations built around IEC-sized motor envelopes. Mounting uses an IEC flange with accuracy N, so shaft alignment remains suitable for precision couplings. Power and signal wiring exit through a single block with one M40 power connector and one SpeedTec-ready feedback connector, which reduces cable crowding at the motor. This arrangement keeps the connection area compact when the motor is installed near guarding or adjacent axes. Commutation and velocity feedback are provided by a resolver, which tolerates vibration and heat while sending analog sine-cosine signals to the drive. The motor uses winding code Q, which corresponds to a configuration intended for continuous-duty servo operation.

The feedback system has a resolution of 2 poles, giving the drive two electrical cycles per mechanical revolution. The sensor provides single-turn inductive feedback, so absolute position is retained within one full revolution without multi-turn electronics. Torque is transmitted through a smooth shaft, which works well with clamp-style couplings and avoids keyway-related stress at the output. The rotor length index is 4, which is the longest stack available in this frame and supports higher continuous torque density. The motor is supplied without a brake, so holding torque must be provided by external hardware when the axis is stopped.
