Parker Hannifin, the global leader in motion control technologies, has broadened its range of frameless torque motors with the introduction of its new TK130 models. Building on the features of the existing TK range, the new, smaller models offer simplified mechanical design, precise motion and high dynamic performance, all in an extremely robust package.

Based on proven brushless technology, the Parker TK motors have been designed for use in high performance applications requiring exceptionally smooth rotation, high positional accuracy and high dynamic performance, such as machine tool indexing and rotary tables. The robust design also makes them particularly suitable for harsh environments, including wind or water turbines, mixers, pulpers or crushers.

Delivered as kits consisting of separate stator and rotor elements with large inner diameters, the efficient and effective gearless design of the TK motors is intended to be directly integrated into the mechanical structure of the machine. The load is then directly connected to the motor’s moving part, leading to simplified mechanical designs, reduced footprint and less weight.

As the TK range of motors have no mechanical parts subject to wear, the lifetime of the whole system is increased and maintenance costs reduced significantly. The absence of gears between the load and the motor also suppresses the backlash and play inherent in conventional mechanical transmissions, resulting in greater rigidity and superior accuracy.

Available as either naturally ventilated or water cooled models, the Parker TK motors are particularly suitable for use in harsh environments, offering high temperature resistance, up to 150°C, as well as providing complete immunity to lubricants.

In addition, the TK motors can be customised to suit the individual needs of a specific application, both in terms of mechanical design and subsystem integration.
