Brake Motor Reference

ActionJac™ Worm Gear Screw jacks and Electric Cylinders can be supplied with industrial quality. Brake motors include a spring actuated, electrically released braking mechanism which will hold a load when the power is off. In normal operation, power is applied and removed to the motor windings and brake release simultaneously.

If it is desired to operate the brake separately, as when used with a speed control, the brake needs to be wired externally. Motors provided by Nook Industries can either be supplied with the brake wired externally to accommodate speed controllers, or internally for simplicity of use.

Standard motors are: 3 phase 208-230 / 460 VAC, 60 Hz. 1,725 rpm. Also available are single phase motors at: 115 / 230 VAC, 60 Hz. 1,725 rpm. Standard 3 phase and single phase motors are rated for 50% duty. Wash Down and Explosion Proof motors are rated for continuous duty.

NOTE: for inverter duty motors or additional options, contact Nook Industries.
