SEM Brushless Servomotors

HJ Series Servomotor

The HJ series combines the latest high power (NdFeB) magnets with a new large diameter shaft and short body design. The HJ motor offers increased inertia, performing with high stability at low speeds and has been designed for machine tool applications in particular. Frame sizes in the new range are 96, 116, 155 mm square.

HR Series Servomotor

The HR series offers a more cost effective range of brushless servomotors with a performance range of 1.5 Nm (13lb-in) to 25 Nm (219 lb-in). The use of high grade Neodymium-Iron-Boron (NdFeB) magnets provide a peak torque to stall torque ratio that covers the majority of applications. These are available in the following frame sizes; 92, 115, 142 mm square.
