Product Description:

The AKM42G-EKCNR-00 is a servo motor manufactured by Kollmorgen for the AKM Synchronous Servo Motors series. In industrial automation, it delivers exact torque and speed control so a drive can position tooling, conveyors, or actuators with repeatable accuracy. The motor uses the 42 frame size and Kollmorgen’s standard customization level, so its mechanical dimensions and electrical pinouts follow published catalog values. It is intended for closed-loop motion systems where stable response and predictable motor data are important during operation. This model suits compact machines such as carton sealers, gantry axes, or labeling heads that need a balance of inertia and continuous torque.

A mechanical holding brake is absent, so machines must rely on the drive or external clamps for static load support; the motor is supplied without a brake. Power and feedback exit the housing through 2 SpeedTec Ready connectors, allowing quick bayonet-style cable connection. This arrangement keeps separate connections at the housing and supports orderly routing in compact machine layouts. Rotor position information is supplied by a Resolver, giving analog sine-cosine signals that resist electrical noise and high temperatures. The feedback element senses 2 poles, so the electrical cycle count per mechanical revolution remains fixed and influences velocity loop bandwidth. The motor body spans 84 mm across the mounting face, a size that fits tight equipment envelopes while still accepting a standard ISO flange.

Position tracking is limited to one mechanical revolution because the resolver is configured for single-turn inductive reporting; applications that require multi-turn data must use an external encoder. That feedback arrangement supports commutation and position evaluation with a simple analog interface. Torque is transferred through an open keyway shaft so couplings can lock positively without set screws. The resolver hardware is in Size 10/15/21. Winding code G sets the phase resistance and torque constant to match medium-voltage AKD drives.
