Product Description:

Kollmorgen manufactures the AKM44E-EKM22-00 as part of the AKM Synchronous Servo Motors series. This brushless servo motor is used for closed-loop positioning and velocity control in automated machinery such as pick-and-place heads, indexing tables, and electronic assembly axes. In these systems, it converts drive current into controlled rotary motion so commanded moves can be repeated accurately under changing loads. It is supplied in a standard configuration for use with compatible Kollmorgen drives and gearheads.

The motor is equipped with a 24 V holding brake that secures the load when power is removed, which helps prevent back-driving on vertical axes. Its housing has a frame dimension of 84 mm, allowing installation in tight spaces while still dissipating heat through the stator jacket. A rotor length index of 4 provides additional active iron for higher torque than shorter versions in the same frame. Position information is supplied by a Comcoder feedback system, which combines commutation tracks and incremental channels in one device. With a resolution of 2048 lines per revolution, the drive receives 8192 counts per revolution after quadrature evaluation for smooth velocity control and fine electronic gearing.

Mechanical power is delivered through an open keyway shaft, which provides positive torque transfer for pulleys or couplings. The feedback package is a single-turn optical device, so it reports position within one revolution without multi-turn tracking. That arrangement suits axes that do not need stored position data across multiple shaft revolutions. Its signal format follows the EPC 15T code, so the connected drive must support that protocol for feedback processing. The winding designation e corresponds to stator electrical values that must match the continuous and peak current capability of the selected drive.
