Brushless synchronous electric torque motor
10 - 1 430 Nm, 0.7 - 13.3 kW ESR Pollmeier

In applications with high torques at low speeds, ESR torque motors are often a good alternative to geared motors or motor-gear box combinations. These direct drives have a higher stiffness and position accuracy compared to solutions with gear boxes. The lack of parts with backlash and friction results in longer lifetime and reduced wear and tear.

Depending on the design type, the torque motors with integrated bearing can be used directly as rotary table or can be built into the machine as easy as a conventional servo motor. Alternatively, we provide torque motors as a kit with separate stator and rotor.

Characteristics of the torque motors

Torques of up to 600 Nm and more, peak up to 1,400 Nm
highest stiffness of the drive system at particularly compact size
maintenance-free, since brushless
high dynamics and accuracy due to optical encoders, optional low-priced magnetical position sensors (single- or multiturn)
high power density through rotor with rare earth magnets
available ready for installation as flange motors with full shaft, hollow shaft, or pad-type flange; as complete rotary tables, or as motor assembly without bearings
easy connection of motor and encoder using connectors
self-cooling, on request cooling through external fan motor
holding brake optional
