Product Details:

KOLLMORGEN AKM42G-EKCNR-01 is a large frame permanent magnet synchronous servo motor from Kollmorgen AKM series, fitted with resolver feedback and smooth plain shaft. It delivers higher continuous stall torque compared with AKM42E models, designed for heavy-duty axes that run under frequent impact load and harsh industrial conditions. The suffix 01 represents a special factory configuration tailored for OEM heavy machinery, with adjusted bearing tolerance and internal assembly specifications for shock-prone working scenarios.

This servo motor adopts contactless inductive resolver as position feedback. Without fragile optical components, the resolver can withstand strong mechanical shock, wide temperature swing and oil mist contamination common in forging and stamping workshops. It converts rotor angle and speed into stable analog signals and sends data to matched Kollmorgen AKD servo drives to build a reliable closed-loop motion system. Separate rotatable M23 connectors for power and feedback circuits isolate power noise from sensitive position signals and reduce electromagnetic interference inside crowded electrical cabinets.

This variant is non-brake design without integrated holding brake, suitable for horizontal heavy feed axes and continuous transfer structures where static shaft locking after power loss is not required. The smooth plain shaft allows 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 damage during long-time heavy cyclic operation. The motor housing reaches IP54 protection grade against workshop dust and incidental coolant splashing. Optimized low cogging magnetic circuit suppresses torque ripple, ensuring consistent rotation stability under fluctuating heavy load.

It supports torque control, speed control and position control modes, and all motion parameters can be tuned conveniently via Kollmorgen 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 resolver signal calibration, heavy impact cycle test, insulation resistance inspection and running noise check to guarantee stable performance in multi-shift heavy industry production lines.

It is widely deployed on hot forging auxiliary axes, heavy stamping transfer lines, thick plate metal forming machines, large hydraulic press feeding systems and heavy bulk conveying equipment. Typical application axes include heavy progressive feed slides, material pulling modules, forming transfer platforms and reciprocating pushing units. Automation integrators select this high-torque resolver variant for its excellent anti-impact performance, stable heavy-load output and seamless compatibility with Kollmorgen AKD motion control ecosystem.
