ETEL has introduced its most advanced model of torque motor, the TMK series. "Continuing ETEL's reputation as a worldwide provider of direct drive technology, the TMK motor range has an electromagnetic design and enhances the concept of torque motors at high speeds without necessitating compromises on other performance criteria," said a company spokesperson.
According to the company, the TMK series is the result of market demand toward a desire for higher-speed rotary motors that still maintain the amount of torque provided in other models, such as ETEL's TMB series. "Due to its rotor design which utilizes buried magnet technology along with field weakening, it is able to rotate with speeds of up to nine times greater than a typical torque motor's standard working speeds," said the spokesperson. "With the buried magnet technology also providing a higher flux concentration, the TMK series motors can produce up to 30% more continuous torque compared to traditional torque motors of the same size. Along with that, it uses liquid cooling to increase its continuous torque even further. With its patented design minimizing force ripple, the TMK series maintains a high force density while other anti-cogging motor designs sacrifice performance."
The TMK torque motor series recently won the Innovation Award in Paris, France, at the "Industrie 2014" international industrial fair, according to the company. The fair's judges, a team composed of about 20 specialized journalists, said, "The TMK motor is an innovative product enabling new functions in the area of milling and turning in the machine tool industry that will lead to higher technology end products and lower manufacturing costs."
ETEL's TMK torque motors are available in 24 different sizes with six diameters, from 198 to 1,050 mm, and four heights to cover a range of continuous torque from 80 Nm to 10,800 Nm. It is also able to reach a maximum peak torque of up to 20,000 Nm. "TMKs are well adapted for high-end machine tool applications and rotary tables in which one needs to combine accurate positioning with very high torque at low speeds," said the spokesperson. "The TMK series is able to achieve this while being able to switch to a dynamic mode reaching very high speeds at lower torque levels."
The TMK also has the option of ETEL's IMTHP thermal module which is designed to enable users to reduce their amount of safety margins while receiving precise and reliable temperature monitoring. ETEL torque motors are compatible with most CNC controllers.
