Frameless torque motor TKH series

brushlessthree-phasemodular

The TKH series is a super high torque density, thin ring torque motor range, offering more than 20% torque increase compared to the TK series and the highest continuous torque density in its class.








Designed and entirely manufactured in Italy with a mostly local supply chain, the TKH series ensures a shorter and more reliable supply chain, increased flexibility and fast response times. The highly modular design, with up to 145 variants, allows fast delivery and reduced risk of stock shortages and downtime.








Optimized for outstanding performance at low to medium speed and for rapid and precise positioning, TKH torque motors are equipped with an innovative electromagnetic circuit and a magnet dovetail positive locking system. Accurate magnetic circuit design and strict manufacturing tolerances guarantee minimal cogging ripple and smooth torque delivery, even in demanding operating conditions.

Research and scientific instrumentation

Thanks to their high torque capability, robust mechanical design and suitability for continuous duty, TKH motors are particularly suited for heavy-duty and high-performance industrial environments.

Characteristics:

TKH frameless torque motors are engineered for seamless integration into custom equipment, featuring a robust construction with a three-phase stator encapsulated in epoxy resin and high-performance rare earth magnets.

Stator characteristics:

Compact design with high efficiency and reliability

Advanced encapsulation with superior thermal properties

–Surge-hardened Class H insulation for high DC voltages

Rotor characteristics:

Isotropic surface-mounted permanent magnet design for reduced cogging

High-temperature coated magnets for enhanced thermal stability

Custom design and co-engineering:

Although the TKH series represents the most standardized and catalog-oriented solution within the PHASE torque motor portfolio, every TK and TKH motor is developed through close collaboration between PHASE engineers and the customer.

By combining PHASE expertise in torque motors, power electronics and energy systems with the customer’s application know-how, we deliver custom and semi-custom solutions optimized for performance, integration constraints and operating conditions.

The modular architecture of the TKH series allows mechanical, electromagnetic and thermal customization, ensuring maximum design flexibility while maintaining short lead times and high reliability.
