Product Description:
The AKM54L-ANC2R-00 is a synchronous servo motor produced by Kollmorgen for the AKM Synchronous Servo Motors series. It is built for precise velocity and position control on compact industrial axes and comes in a standard customization level with an IEC flange of accuracy class N, a frame dimension of 108 mm, and a 130 mm bolt circle around a 110 mm pilot diameter. The IEC flange and pilot arrangement suit standardized motor mounts in compact automation equipment, helping maintain accurate centering during installation. Mechanical coupling is through a smooth 24 mm shaft, and two SpeedTec-ready connectors support quick power and feedback hookup. A 24 VDC holding brake rated at 14.5 Nm helps prevent load drift when power is removed.
The motor delivers a continuous output of 8.13 Nm at a rated speed of 4500 rpm, producing 3.83 kW from 400 VAC windings marked with the L designation. At standstill, it draws 12.5 Arms and has a copper resistance of 0.63 Ω, values that help size the matching drive and estimate heating under load. The winding inductance is 3.50 mH, which helps limit current ripple, and rotor length index 4 extends the magnetic stack without increasing the frame size. Copper resistance and inductance also shape current response during acceleration and steady running, which supports predictable closed-loop motor behavior.
For short-duty bursts, the AKM54L can reach 37.5 Nm of peak torque, and maximum current rises to 37.5 Arms for brief acceleration demands. Rotor inertia is 12 kg·cm², which helps balance quick acceleration with steady control on compact axes. Resolver feedback in size 10/15/21 is single-turn and inductive, uses two magnetic poles, and returns rotor position to the controller without batteries. This feedback arrangement supports commutation and speed control while keeping the sensing setup compact.
