Product Description:

The AKM21C-ENCN2-00 synchronous servo motor is produced by Kollmorgen and belongs to the AKM Synchronous Servo Motors series. Within an automation cell, this motor converts controlled electrical input from a servo amplifier into rotary motion with tightly regulated torque, speed, and position. Packagers, small robots, and indexing tables rely on this kind of motor to maintain coordinated movement with minimal settling time. Because it is built for closed-loop servo operation, the paired drive can correct disturbances quickly during short, repetitive indexing moves.

This unit uses two SpeedTec Ready connectors, allowing separate power and signal terminations with keyed locking that simplify cable routing and reduce hookup errors. Rotor position data is provided by a Comcoder, an integrated feedback device that combines an incremental track with absolute referencing for startup alignment. Its native interpolation delivers 2048 lines/rev, giving the controller fine angular resolution at low speeds. With a frame dimension of 58 mm, the housing fits compactly into small pick-and-place axes while still supplying the torque level associated with the AKM size 2 platform. A smooth shaft eliminates keyways, simplifying coupling to low-inertia loads and helping reduce backlash in clamping hubs.

The encoder track is single-turn optical, so the position reference resets after one revolution and no battery is required. Signal conditioning follows the EPC 15T format, matching drives that accept RS-422 encoder streams. Electromagnetic behavior is set by winding code C, which establishes the electrical characteristics used by low-voltage, high-current amplifiers. The rotor length index keeps inertia low, and the motor is supplied without a brake, so holding torque during power off must be provided externally. This arrangement is useful on axes where a separate mechanical holding method is already part of the machine.
