Product Description:

The AKM22C-ACFNR-00 is a synchronous servo motor produced by Kollmorgen and supplied in the AKM Synchronous Servo Motors series. The unit is designed to translate commanded current into proportional torque so that automation controllers can execute precise velocity and position loops. By combining compact stator geometry with low electrical time constants, it supports rapid acceleration and deceleration in equipment such as electronic assembly heads, light conveyors, and laboratory positioning stages where repeatable rotary motion is critical to process quality.

The motor is delivered without a brake, so holding torque must be provided externally when the axis is stopped. A square housing based on a 58 mm frame dimension simplifies drop-in mounting on metric brackets. Rotor position is detected by a resolver, a passive electromagnetic device that tolerates high temperatures and electrical noise. This resolver uses 2 poles, which establishes the electrical cycle count used by the drive for commutation. Position information is provided as a single-turn inductive signal, giving absolute angular data for one revolution without the need for batteries or multi-turn gearing. A keyed shaft secures pulleys or couplings against slip during start-stop duty.

The stator face follows an IEC with accuracy N flange, allowing direct attachment to standardized gearheads and actuators while maintaining concentricity tolerances. Electromagnetic characteristics come from the C winding, which matches back-EMF and resistance values with common low-voltage servo drives. The motor uses standard customization, so cable exits, seals, and coatings follow the standard factory configuration. The active magnetic stack uses rotor length index 2, balancing inertia and continuous torque for mid-range load profiles.
