HIWIN GmbH is a specialist in standard and customer-specific drive solutions. The company's product portfolio features linear guideways, ballscrews, linear, torque and servo motors and complete positioning systems, including linear motor axes, rotary tables and belt and spindle drive axes. As it has its own production facilities in Germany, HIWIN is able to ensure short delivery times and optimum quality. The latest achievement by HIWIN’s engineers is a new fast-moving water-cooled torque motor for particularly demanding applications based on the popular TMRW series.
The innovations are not apparent from the exterior - that is to say, the stator - of the new TMRI direct drives. However, the grooved high-performance internal rotors form an assembly with a laminated magnet carrier in the center, instead of the previous homogeneous steel component. This ingenious feature has broken the previous upper speed limit thanks to the reduced eddy current losses. HIWIN's engineers have also arranged the permanent magnets in the rotor in such a way that the magnetic flux density rises, with the TMRI torque motor also reaching a new level for torques as a result. The new drives thus offer higher speeds and torques and greater efficiency than the existing TMRW series.
