Product Description:

The AKM42G-BKCNR-00 is a servo motor produced by Kollmorgen for the AKM Synchronous Servo Motors series. As a rotary actuator, it supplies controllable torque and speed to automated equipment such as pick-and-place axes and material handling stages, linking directly to a drive through digital feedback. The motor occupies the AKM product family’s 42 frame code and uses rotor length index 2 to balance torque density against overall mass for mid-range motion tasks in industrial automation.

The electrical interface is provided through 2 SpeedTec Ready connectors, allowing quick-lock power and feedback cabling during cabinet assembly. Position and velocity signals originate from a resolver, giving angle information that remains stable over temperature swings and electrical noise. That resolver operates in a single-turn inductive format, so one mechanical revolution equals the full electrical span without the need for batteries. The feedback channel preserves a native resolution of 2 poles, which the drive uses to close the servo loop. Mechanical mounting follows a NEMA flange, enabling the motor to bolt to standard gearheads or brackets without custom adapters. The unit is supplied without a brake, so holding torque must be furnished by an external mechanism or continuous drive current when the application requires static positioning.

The housing uses an 84 mm frame, giving a compact cross-section that fits tight machine spaces while still allowing adequate winding volume. Output power is transmitted through an open keyway shaft, providing positive coupling to pulleys or couplings without setscrew slip. Feedback hardware is packaged in a size 10/15/21 resolver body, which matches Kollmorgen’s standard harness sets for the AKM family. Magnetic characteristics follow the G winding, letting the motor reach its rated torque at drive voltages typical of 230 V class inverters. Customization level is standard.
