CENTRIFUGAL MECHANISMS

The centrifugal mechanism determines the speed at which the stationary electrical switch actuates. The centrifugal mechanism is composed of a conical spring disk mounted to a bracket which is press-fit onto the motor shaft. Weights are attached to the spring disk and centrifugal force causes the spring to snap. This moves the spool on the centrifugal mechanism away from the stationary switch as the motor achieves approximately 75% of its normal running speed.

STATIONARY SWITCHES

The stationary switch is the current carrying component of the TORQ Syncrosnap® centrifugal switch. These switches are designed to fit within the motor with a minimum of assembly time required. They can also be furnished to perform secondary functions when the equipment attains full speed.

Each unit size can be utilized for single-contact, dual-contact, multi-speed and added features of multiple circuitry when needed. Terminal board arrangements are also available for field connection changes in speed, direction, etc. when desired.
