Product Details:

KOLLMORGEN AKM43E-EKCNR-01 is an 84mm frame permanent magnet synchronous servo motor from Kollmorgen AKM series, fitted with resolver feedback, keyway shaft and customized shaft seal structure. The suffix 01 stands for factory special sealing configuration, which is specially optimized for workshop environments splashed with cutting coolant and fine metal dust. It delivers stable medium-high stall torque and reliable overload capacity, suitable for cyclic feed axes under continuous mechanical vibration and temperature fluctuation.

This servo motor adopts contactless inductive resolver as position feedback. Without fragile optical components, the resolver can endure heavy shock, rapid temperature change and coolant mist pollution that easily damage ordinary optical encoders. It converts rotor angle and rotational speed into analog signals and transmits data to matched Kollmorgen AKD servo drives to build a stable closed-loop motion control system. Separate rotatable M23 connectors for power and feedback circuits isolate power noise from sensitive position signals and reduce electromagnetic interference inside densely arranged electrical cabinets with inverters.

This variant is non-brake design without integrated holding brake, intended for horizontal feed axes and rotary positioning structures where static shaft locking after power loss is not required. The keyway shaft ensures stable torque transmission with reducers and couplings and prevents slipping under variable cutting load. The upgraded shaft seal structure of this 01 version blocks coolant particles and metal debris from entering the bearing cavity, effectively extending bearing service life in machine tool processing workshops. The stator winding uses Class F insulation material and integrates PTC thermal sensor for real-time overheat protection during long-cycle cutting operation. The motor housing reaches IP54 protection grade. Optimized low cogging magnetic circuit suppresses torque ripple, ensuring smooth rotation and consistent feeding precision.

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 resolver signal calibration, sealing tightness inspection, cyclic cutting load test, insulation resistance check and vibration noise monitoring to guarantee stable performance in multi-shift CNC production lines.

It is widely deployed on CNC machining centers, metal milling equipment, automatic drilling machines, grinding auxiliary axes and metal cutting automation cells. Typical application axes include linear feed slides, rotary positioning tables, tool adjustment modules and cross feeding units. Automation integrators select this sealed resolver variant for its outstanding coolant resistance, shock-proof feedback performance and seamless compatibility with Kollmorgen AKD motion control ecosystem.
