Break: by springs, the brake linings are pressed against the outer surface of friction pulley to perform braking. Use the brake only when quick stop is absolutely required in emergency, for repair or checkup.

A friction clutch is used for gentle starting and acceleration, thereby preventing the motor from being overloaded. The motor shaft has a friction boss provided with a friction clutch and the horizontal shaft has a friction pulley. After starting, the motor instantly turns at critical speed, the friction clutch lining is pressed against the internal surface of the friction pulley via centrifugal force and the power is transmitted to the friction pulley (horizontal shaft side) as the friction pulley and lining slip with each other. Normally, the bowl of small-size purifiers reaches its rated speed of rotation in less than 5 minutes, and middle-size and large-size in less than 10 minutes.

The motor power is transmitted via the friction clutch to the horizontal shaft so as to mitigate the starting load. When the motor is started, it immediately reaches near the rated speed, gradually accelerating the bowl via friction clutch. During this while, the rated motor power is exceeded and, therefore, a motor enduring an overload is used in this type of motor.
