Product Description:

The AKM42E-ACC2C-01 is a synchronous servo motor produced by Kollmorgen for the AKM Synchronous Servo Motors series. Within an automation cell, it serves as the prime mover for axes that demand accurate position, speed, and torque regulation, allowing drive amplifiers to execute deterministic motion sequences without mechanical backlash or transmission loss. The motor supports repeatable indexing, positioning, and speed-controlled moves in packaging, assembly, and material-handling equipment. Its closed-loop operation helps connected drives maintain stable motion when cycle timing and load response must remain consistent.

A factory-installed 24 V holding brake secures the shaft whenever the drive is disabled, preventing load drift on vertical or overhung mechanisms. Power and feedback cabling are attached through 2 SpeedTec Ready connectors, a layout that supports tool-free installation and maintains shield integrity. The motor body spans 84 mm across the square frame, matching compact machinery footprints while still providing useful thermal surface area. The output uses a keyway shaft, which supports positive torque transfer to pulleys or couplings without relying only on clamping force. An internal shaft seal keeps lubricant and contaminants separated from the stator cavity so the unit can be mounted in environments with light oil mist or dust. Position retention and commutation are referenced by the servo’s SFD digital feedback element, a single-cable arrangement that carries encoder data alongside drive power.

The feedback stack provides single-turn inductive sensing with four lines of resolution to support tight loop bandwidths while resisting magnetic interference. The encoder is listed as Size 10/15/21, indicating compatibility with multiple drive families that recognize this feedback protocol. Mechanical attachment follows the IEC flange with accuracy N standard, simplifying alignment to planetary gearboxes or direct machine frames. Dynamic capability is tailored by the motor’s rotor length index 2, a designation that balances inertia and torque density for mid-range load profiles. Winding designation e identifies the stator copper layout, and the dedicated shaft seal works with the keyed output during typical industrial duty cycles.
