Product Description:

The CKM02A-AKMN2-00 is a compact brushless servo motor manufactured by Kollmorgen for the CKM Servo Motors series. It serves as an electromechanical actuator that delivers regulated torque and speed to small-frame automation axes in packaging, pick-and-place, and laboratory devices where precise, repeatable motion is required for product handling and tool positioning. Its brushless design and encoder feedback support closed-loop operation during positioning, acceleration, and speed-controlled movement.

The motor operates from a nominal supply of 220 VAC, and its phase windings draw a continuous current of 1.6 A while producing rated electromagnetic effort. Under these conditions, it generates a steady shaft torque of 0.637 Nm at a rated speed of 3000 rpm, providing a mechanical power output of 0.2 kW. This continuous operating point can be used to select a compatible drive amplifier and suitable gearing so commanded motion profiles remain within the motor’s thermal limits.

Short-duration demands are supported by a peak torque reserve of 1.911 Nm, which accommodates acceleration spikes without exceeding magnetic saturation. A torque constant of 0.46 Nm/A indicates the proportional relationship between stator current and developed torque, supporting precise current-loop control. The armature has an inductance of 16.2 mH and a resistance of 6.40 Ω, which influence drive pulse-width modulation behavior and heat generation in the windings. The motor also has a back EMF constant of 28 V/krpm, a 2500 ppr commutation encoder for position feedback, and a rotor inertia of 0.17 kg·cm² that supports rapid speed changes. Its mass is 1.03 kg, making it suitable for compact axes where overall moving weight must remain low. A keyed shaft provides positive engagement with compatible couplings and helps prevent rotational slip under load. The motor does not have a shaft seal, so it is intended for clean, dry environments where protection against moisture or contaminants at the shaft opening is not required.
