Product Description:

The AKM42G-ACMNEH-00 is a permanent-magnet synchronous servo motor built by Kollmorgen and supplied within the AKM Synchronous Servo Motors series. As a compact rotary actuator, it couples with digital drives to deliver closed-loop speed and position control for pick-and-place modules, indexing tables, and light-duty packaging axes. The motor provides responsive torque for high-throughput lines where precise acceleration profiles and minimal maintenance are required in industrial automation. Its design supports accurate motion changes during frequent starts, stops, and short indexing moves. This makes it suitable for equipment that must move small loads quickly while maintaining controlled positioning.

This model is supplied without a brake, so holding torque during power-off must be achieved through external mechanics or drive torque. The mounting interface follows an IEC flange, which permits direct installation on machines that use the same standardized bolt circle. The motor has an 84 mm frame dimension, which sets the housing cross-section and suits machinery where panel depth is restricted. It uses rotor length index 2, which indicates a medium active length within the AKM42 frame and balances torque output with inertia. Electrical performance is matched by its winding designation G, which corresponds to coil resistance and inductance values used with common servo amplifiers. The compact housing also helps preserve clearance around adjacent machine components in tightly packed assemblies.

For mechanical transmission, the motor uses a keyway shaft, which provides positive torque transfer and repeatable phase alignment with pulleys or couplings. The front face machining follows accuracy N, a tolerance class that limits runout and helps maintain concentricity with gearboxes and load fixtures. A keyed output shaft can reduce the chance of relative movement between the shaft and hub under changing loads. Controlled front-face accuracy also helps reduce misalignment at the coupling point, which can improve running smoothness in connected components. These features support stable installation in compact servo-driven machinery.
