Product Description:

The CKM08A-AKM22-00 servo motor is manufactured by Kollmorgen for the CKM Servo Motors series. It is a brushless permanent-magnet unit that delivers closed-loop motion for pick-and-place heads, small conveyors, and packaging jigs in industrial automation. By integrating the rotor, stator, and an internal encoder inside a short frame, the device provides precise torque and speed regulation without requiring an external gear reducer. A molded side-exit power connector keeps the body profile narrow for dense multi-axis mounting on machine frames.

Its windings are intended for a supply of 220 VAC, allowing connection to standard servo drives. Under rated conditions, the motor outputs 0.75 kW of mechanical power at a shaft speed of 3000 rpm. At that operating point, it produces 2.387 N·m while drawing a continuous phase current of 4.3 A. The 300 mm shielded pigtail terminates in an IP20-rated connector that fits cabinet-mounted extension cables. Position and commutation feedback come from a 2500 ppr incremental encoder mounted on the shaft. A back-EMF constant of 36.83 V/krpm aligns the motor voltage with the drive’s DC bus, while the rotor inertia of 0.94 kg·cm² balances responsiveness with load stability.

The shaft can reach 3750 rpm for short bursts, and the drive may deliver a peak phase current of 12.9 A during acceleration. That current produces a peak torque of 7.161 N·m before magnetic saturation occurs. With a torque constant of 0.61 N·m/A, commanded current translates linearly into output torque, simplifying control-loop tuning. The available transient torque helps the motor overcome static friction, while the low-inertia rotor and high-resolution feedback support rapid positioning. These operating characteristics are suited to intermittent acceleration cycles that remain within the drive and motor limits.
