Product Description:

The CKM30B-AKCNT-00 is a brushless servo motor manufactured by Kollmorgen as part of the CKM Servo Motors series. In automated machinery, it supplies closed-loop rotary motion by converting drive commands into controlled shaft rotation for packaging lines, pick-and-place gantries, and CNC feed axes. The motor’s compact frame facilitates installation in confined machine spaces. Its electromagnetic design supports moderate continuous power while permitting short bursts of elevated torque during acceleration.

Electrical performance centers on a single-phase 220 VAC supply that the drive converts into three-phase excitation for the windings. At a rated current of 13.7 A, the motor produces a continuous output of 3.0 kW. This power is delivered at a rated speed of 2000 rpm and a sustained torque of 14.32 Nm. For rapid indexing or load surges, the magnetic circuit can generate a peak torque of 42.96 Nm. The 2.124 mH armature inductance moderates current rise, promoting stable control loops and smooth current regulation. Feedback is supplied by an absolute encoder, while the IP65 dual connector keeps the power and signal conductors sealed against dust and water spray.

A torque constant of 1.13 Nm/A allows the drive to translate demanded torque into precise current setpoints, and the assembly can accelerate to a maximum speed of 2500 rpm without losing synchronization. Copper losses are governed by an armature resistance of 0.333 Ω, keeping temperature rise predictable during extended duty cycles. The rotor inertia of 17.92 kg·cm² balances quick acceleration with load damping. A keyed shaft provides positive torque transmission to a coupling or driven component. The shaft does not have a seal, which minimizes rotational drag. The motor is supplied without a holding brake, so an external mechanism must secure vertical or safety-critical loads when motor torque is unavailable.
