Product Description:

The AKM22E-CKMN2-00 is a compact synchronous servo motor designed by Kollmorgen for the AKM Synchronous Servo Motors series. With a 58 mm frame size, this motor fits smaller machine axes where space is limited and precise torque control is needed for positioning, indexing, or moderate-speed continuous motion. Mounting follows Alternative Flange Variant C, so the motor can fit applications that do not use a standard ISO square flange outline. In automated equipment, it can serve pick-and-place units, light conveyors, and packaging mechanisms that require coordinated multi-axis motion.

The motor uses a Comcoder encoder, which combines commutation tracks and incremental channels so a separate Hall-sensor ring is unnecessary. Its feedback resolution is 2048 lines/rev, giving the drive detailed position and velocity data for closed-loop control. Position reference comes from a single-turn optical disk, which avoids a multi-turn gear train and keeps the feedback arrangement straightforward. Signal processing is handled through the EPC 15T protocol for compatibility with Kollmorgen digital drives that accept differential RS-422 encoder streams. This arrangement lets the paired servo drive process commutation and incremental feedback through one motor-mounted device, which helps keep wiring compact and response consistent.

The shaft uses an open keyway, allowing torque transfer through keyed couplings without additional machining. The motor is supplied without a brake, so load holding during power loss must be provided by drive torque or an external mechanical device. The stator uses winding designation e, which sets the electrical characteristics expected by the matching drive. This arrangement is suited to installations where the coupling provides the required mechanical interface and where holding force is managed elsewhere in the axis.
