Hysteresis brake structure and principle of operation

● Figures 1 show typical structures of hysteresis brake.

● The hysteresis brake is formed by fixing a stator and a first rotor.

Hysteresis Clutch Feature

FAST RESPONSE

The torque of YSHY series electromagnetic hysteresis brake is independent of slip speed. Torque is directly proportionate to coil current, thus the torque of each unit can be adjusted by varying the current. Once the current is stable, the torque remains constant.

REPEATABILITY

The YSHY series hysteresis brake will always duplicate performance under identical operating

SMOOTH OPERATION

The YSHY series hysteresis brake does not utilize mechanical friction; therefore, operation is smooth at any slip speed.

LONG LIFE

The YSHY series hysteresis brake produces drag torque without physical contact (friction) of parts and are not subject to wear (except the normal wear of antifriction bearings).

EASY MOUNTING

Mounting is effortless - no adjustments to make, no gaps to set. The YSHY series hysteresis brake may be mounted in the horizontal or vertical position.

Running-in procedure

• Unlike other types of clutch and brake, hysteresis clutch and hysteresis brake is noncontact type. Therefore running-in is not required.

• Since it has no wearing part, the torque is maintained semipermanently.

Continuous operation

• Depending on the conditions of use, the surface temperature of the hysteresis clutch and hysteresis brake may rise considerably. Use the product while keeping the surface temperature below 80°C. If the surface temperature exceeds 80°C, relax the operation conditions, and prevent overheat of the product.

(Herein, the surface temperature is mentioned on the basis of the ambient temperature of 30°C. The allowable ambient temperature range is 0 to 40°C.)

Residual torque

• When the hysteresis clutch and hysteresis brake is de-exited while rotating faster than a specific speed (40 to 50 r/min or more), residual torque is not caused, but when de-exited while not rotating, a residual torque (ripple form) of about 5 to 10% of the value before cutting off occurs. To eliminate the residual torque, the following two control methods are known.

(a) Cut off the current while the relative rotating speed of the first rotor and second rotor (stator in the case of the brake) is more than 40 to 50 r/min, or decrease gradually when the relative rotating speed is low.

(b) Pass a current of 30 to 50% of the current value before cutting off, in a reverse direction. In this case, if the first rotor and second rotor are mutually free, the pole are deviated and de-exciting effect by reverse exciting is lost, and therefore the both rotors should not be deviated or the input shaft must be fixed.

The residual torque is almost free from effects of uneven torque when used at exciting current of more than 60 to 70% of the current value at the time of cutting off.
