Product Details:

KOLLMORGEN AKM53-ANCNEJ-00 is a large 142mm frame permanent magnet synchronous servo motor from Kollmorgen AKM series, equipped with EnDat single-turn absolute encoder and smooth plain shaft. It delivers high continuous stall torque and strong overload capacity, optimized for heavy low-speed positioning and cyclic rotary applications that only need absolute angle feedback within one rotation range. The EJ suffix represents special electrical and bearing configuration for heavy-duty molding environments with continuous mechanical shock.

This servo motor uses high-resolution EnDat single-turn absolute encoder for digital position feedback. It can output absolute rotor angle directly after power on within one rotation stroke, eliminating homing operation for limited-travel positioning axes. It transmits stable digital signals to matched Kollmorgen AKD servo drives for closed-loop motion control. Separate rotatable M23 connectors for power and feedback circuits isolate power noise from sensitive digital signals and reduce electromagnetic interference inside high-power electrical cabinets with inverters.

This variant is non-brake design without integrated holding brake, suitable for horizontal heavy feed axes and large rotary indexing tables where shaft locking after power loss is not required. The smooth plain shaft supports flexible coupling assembly for different mechanical transmission layouts. The stator winding uses Class F insulation material and integrates PTC thermal sensor for real-time winding temperature monitoring to prevent overheating during long-cycle fluctuating load operation. The motor housing reaches IP54 protection grade to resist workshop dust and incidental rubber coolant splashing. Optimized low cogging magnetic circuit suppresses torque ripple, maintaining smooth low-speed running and consistent positioning precision for heavy molding processes.

It supports torque control, speed control and position control modes, and all motion parameters can be tuned conveniently via Kollmorgen WorkBench software. Standard IEC flange mounting dimensions support direct replacement of legacy AKM motors, simplifying on-site equipment renovation and spare part swap. Every finished motor passes complete factory validation before shipment, including EnDat signal calibration, heavy low-speed cycling test, insulation resistance inspection and vibration endurance test to guarantee stable performance in multi-shift heavy industrial production lines.

It is widely deployed on rubber molding auxiliary feeding axes, heavy composite forming machinery, large rotary vulcanizing equipment, bulk material handling systems and heavy injection molding peripheral automation. Typical application axes include heavy linear feed slides, large rotary positioning turntables, reciprocating pushing platforms and low-speed heavy transfer modules. Automation integrators select this high-torque single-turn EnDat variant for its excellent low-speed stability, reliable heavy-load positioning and seamless compatibility with Kollmorgen AKD motion control ecosystem.
