ETEL offers the most comprehensive standard torque motors range in the industry. With more than 100 models to choose from, almost any requirement can be successfully fulfilled. ETEL also excels in developing custom torque motors to meet a specific application need.

All ETEL motors benefit from our patented anti-cogging design. This open-slot construction enables an exceptional peak force density of 10 N/cm2 in the magnetic gap, as well unparalleled thermal efficiency, which is a significant advantage for thermal-drift-sensitive precision machines.

TMB are frameless torque motors, with a cage for water cooling.
TML are cageless torque motors, designed for air-convection cooling.
TMM are cageless torque motors, designed for conduction cooling.
