Parker - TK - TKW Series - Frameless Torque Motor

Frameless Torque Motors
up to 21000 Nm


Delivered as separate rotor and stator to be integrated into the mechanical structure of the machine, TK series torque motors lead to simplified designs, reduced costs, and increased accuracy. TK Series distinguishes from existing solutions by an exceptional robustness, making them particularly adapted to harsh environments. Benefiting from unprecedented know-how in the design and manufacture of torque motors, TK Series can also be delivered as complete sub-assemblies including frame, cooling system, bearings, feedback sensor.
