Product Details:

KOLLMORGEN AKM43E-SSSSS-02 is an 84mm frame permanent magnet synchronous servo motor from Kollmorgen AKM series, fitted with ComCoder incremental feedback and integrated fail-safe holding brake. It runs at rated speed up to 3000 rpm with stable medium torque output, built for vertical rotary rollers and tension-controlled axes that require secure shaft locking once power supply cuts off. The suffix 02 represents OEM customized assembly specification, tuned for continuous web handling and roll-to-roll processing equipment.

This servo motor uses ComCoder incremental encoder to send pulse signals and motor commutation data to matched Kollmorgen AKD servo drives, forming closed-loop speed and tension control. It delivers steady speed tracking for master-slave synchronous motion, while it does not retain absolute position data after power loss. Separate rotatable M23 power and feedback connectors isolate power circuit from sensitive pulse signals and reduce electromagnetic noise interference inside electrical cabinets filled with inverters.

This variant comes with built-in static holding brake. When the brake coil de-energizes, the brake locks the rotor shaft tightly to prevent roll back and material unwinding accidents, which is critical for vertical unwind and rewind rollers. It adopts smooth plain shaft for coupling and pulley installation. The stator winding uses Class F insulation material and integrates PTC thermal sensor for real-time winding overheat protection during long-hour continuous tension operation. The motor housing reaches IP54 protection grade to resist workshop dust and incidental liquid splashing. Optimized low cogging magnetic circuit reduces torque ripple, ensuring uniform rotation speed and stable tension output to avoid material stretching or wrinkling.

It supports torque control, speed control and position control modes, and all motion parameters can be tuned conveniently via Kollmorgen WorkBench drive 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 brake holding force test, ComCoder pulse signal calibration, tension stability cycling test, insulation resistance inspection and vibration noise monitoring to guarantee reliable performance in multi-shift converting production lines.

It is widely deployed on film slitting machines, paper rewinding lines, flexible packaging converting equipment, textile calender rollers and label stock processing systems. Typical application axes include brake-assisted rewind rollers, vertical unwind modules, tension control drums and synchronous transfer rollers. Automation integrators select this ComCoder brake variant for its reliable power-off locking function, consistent tension regulation and seamless compatibility with Kollmorgen AKD motion control ecosystem.
