HJ116 Servomotors

HJ116 Brushless 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.
