Product Description:
The CAKM52M-SSYNR-02 is a brushless servo motor manufactured by Kollmorgen within the CKM Servo Motors series. It converts electrical commands from a compatible servo drive into controlled rotary motion and repeatable torque. The motor is intended for closed-loop industrial automation tasks that require accurate positioning. Typical applications include packaging lines, material-handling axes, robotic equipment, and general motion platforms.
This model delivers a continuous shaft output of 6.88 Nm at 60 °C while drawing 13.1 Arms. Together, these values represent the thermal steady-state load that the motor can sustain without additional cooling. The electromagnetic design provides a torque constant of 0.66 Nm/Arms, so each ampere of phase current produces approximately two-thirds of a newton-meter. A back electromotive force constant of 42.4 V/krpm indicates the voltage generated by the windings during rotation and supports appropriate drive selection for regenerative operation. The line-to-line inductance of 2.5 mH works with the 0.49 Ω phase resistance to control current rise time and reduce ripple. A shaft-mounted resolver supplies absolute position feedback, while five pole pairs establish the relationship between the stator field’s electrical frequency and the shaft’s mechanical speed. The motor constant is 0.770 Nm/√W, indicating the amount of torque produced relative to the square root of power loss.
The motor reaches a maximum speed of 3200 rpm and supports a peak current of 39.4 Arms. Its peak torque capability is 21.9 Nm, providing additional output for rapid acceleration and short-duration load changes. The windings can operate from DC bus voltages up to 320 Vdc, allowing connection to common servo drives without derating. A rotor inertia of 6.2 kg·cm² balances responsive acceleration with practical load matching for automated machinery. The housing is 15.0 inches long, providing a clear dimension for machine-space planning, and the complete assembly weighs 13 lb to limit moving mass in gantry or robotic applications.
