Product Description:

The AKM33H-ANCNC-00 is a synchronous servo motor produced by Kollmorgen within the AKM Synchronous Servo Motors series. This compact unit is intended for closed-loop position, velocity, and torque control in automated machinery such as packaging stations, pick-and-place axes, and indexing tables. By coupling directly to the load through its shaft or through a gearbox, the motor converts electrical energy into controlled rotation, supporting fast cycles and repeatable motion profiles common in industrial automation. Its compact housing also suits machine layouts where installation space is limited but accurate motion is still required.

In mechanical terms, the motor’s frame dimension is 70 mm, a size that fits power applications while keeping the overall footprint small. The rotor length index of 3 indicates the third stator-rotor stack in the 70 mm frame, which increases continuous torque without increasing diameter. Power and feedback are routed through 2 SpeedTec Ready connectors, which use keyed quarter-turn locking for secure attachment. Torque is delivered through a smooth shaft that mates with standard couplings where keyed joints are unnecessary. Kollmorgen assigns the H winding designation to this model, indicating voltage and current constants suited for higher bus voltages in modern servo drives. Position information is generated by an SFD feedback encoder that sends digital data to the drive for sinusoidal commutation and offset detection. The motor is supplied without a brake, so holding torque must come from the drive or external mechanics.

For applications that rely on absolute position at power-up, the encoder operates in single-turn inductive mode, removing the need for batteries or homing routines after restart. The encoder housing uses the Size 10/15/21 form factor, which keeps the overall length short while retaining magnetic immunity. Mounting to gearboxes or machine faces is simplified by an IEC flange with accuracy N, which keeps pilot concentricity within the allowed limits for precise shaft alignment. This arrangement supports consistent coupling alignment and leaves a compact axial package for nearby cables and machine components.
