Product Description:

The CKM08A-AKMNT-00 is a brushless servo motor produced by Kollmorgen for the CKM Servo Motors series. It functions as an electromechanical actuator that converts controlled electrical input into precise rotary motion, allowing position or velocity regulation in packaging lines, pick-and-place stations, and similar automation axes. The motor is supplied with a 300 mm shielded power and feedback cable that terminates in IP20-rated dual connectors. Its rotor shaft is machined with a keyway and furnished with a matching key for straightforward coupling to gears or pulleys.

The motor is designed to operate from a 220 VAC supply. Under nominal conditions, the shaft turns at 3000 rpm, providing the continuous operating speed for the driven machine. At this operating point, the motor develops 2.387 Nm of torque and produces a mechanical output of 0.75 kW. It draws 4.3 A to maintain this operating point, supporting the use of compact drives and modest conductor sizes. The absolute encoder mounted in the stator returns unique position data after each power cycle, eliminating the need for homing routines. Because no shaft seal is fitted, the housing should be installed in a clean environment or paired with an external seal where fluids are present.

During acceleration or brief overloads, the motor can deliver a peak torque of 7.161 Nm, providing headroom for high-inertia loads. Electrical response is governed by an armature inductance of 8.6 mH, while the generated counter-electromotive force follows a constant of 36.83 V/krpm; these values support current-loop tuning and bus-voltage selection. A torque constant of 0.61 Nm/A links commanded current directly to torque output, enabling predictable servo performance. The rotor inertia is 0.94 kg·cm², supporting rapid speed changes without excessive drive gain. The motor has an overall mass of 2.54 kg, allowing installation on lightweight gantry axes or end-of-arm tools.
