ELECTROMAGNETICALLY OPERATED MULTI-PLANE BRAKES ETM - ..6


ETM - ..6 brakes must be lubricated /cooled with gear oil of a viscosity of 1.7 to 2.5° E at. 50° C. Suppły voltage - 24 V d.c. In order to protect brake coil against breakdown when the current is switched off the supply system should incorporate a suppressor in the form of a resistor of a resistance 8 to 10 times higher than the resistance of the coil winding connected in parallel to the coil, or a semi-conductor diode or resistor and coil

Large contact surface between brake and machine body and provision of adequate lubrication ensures favourable balance of heat of the brake at max admissible loads. The gap between bush and body considerably reduces the shaft magnetic flux whereby advantageous dynamic characteristics and low residual torque are obtained. The brakes require no adjustment in service.
