1-5 Motor shaft brake
The brakes equipped on SHA-Y series actuators are used to hold the motor shaft in place when the power is
cut off. With small models (SHA25Y, 32Y), the actuator's built-in circuit controls the voltage supplied to the
brake in order to reduce the power consumption while the brake is actuated.
Be sure to use a DC power supply having proper brake excitation voltage and capable of outputting enough
current consumption during suction.
