General technical information on TK frameless motors

The TK series of frameless brushless motors provide the highest torque density available today for direct drive, high performance applications. Unlike traditional torque motrs, TK units have both high torque and high speed capability and thus operate seamlessly both as spindle and table motors.
TK motors consist of separately supplied stator and rotor units suitable for direct assembly inside the structure of the machine. TK motors are three phase, rare earth (Iron Neodymium Boron) permanent magnet units and reach the highest continuous and peak torque density available today, together with high speed and flux control ability over a constant power range up to 10:1.
The rotors use special Phase manufactured magnets with minimized loss factor allowing high speed operation with a thin isotropic rotor.

All rotors are rigid units with mechanical, glue free magnet retention, preloaded carbon fiber sleeve for safe operation even at very high speed.
Rotor are often semi custom units to allow direct coupling to bearings, encoders, brakes.
All TK motors are designed for fluid (water) cooling on the outside of the stator for maximum performance. Conduction/convection cooling is also possible. Constant power operation (flux control) always requires water cooling.
Customized frames with integral cooling or even partial machine subassemblies with bearings and encoders are manufactured on request based on the standard frameless magnetic designs available.
The torque range spans from 10 to 40,000 Nm with maximum diameter 1150mm; above that size, segmented semi custom units are available, currently up to 18 m diameter
