Providing Solutions in centrifugal
Speed Switching for Over 65 years
MADE IN THE U.S.A.
Motor Switch Selector
For 4 pole 60 hertz 3 phase motors with standard shaft sizes.

Convert single phase power into three phase power with our rotary phase converter kits. Torq has customized our proven reliable products to provide you with a starting switch for a three phase motor when used as a Rotary Phase Converter. This design provides you with a highly reliable device which will "switch out" when the shaft is at the proper speed. Since it is electro-mechanical, it responds only to shaft speed - not to line surges or voltage variations. These unique kits allow you to construct your own custom converters from standard stocked components already familiar to you.

  1. ATTENTION: PROPER RUNNING CLEARANCE IS IMPORTANT FOR OPTIMUM PERFORMANCE.
    Running clearance is the nominal distance between the centrifugal mechanism spool and the stationary switch buttons or switch arms when the centrifugal mechanism is at speed and retracted back from the switch. It should be measured when the mechanism is at rest by mechanically compressing the centrifugal mechanism spool to its backplate to simulate the running condition. The centrifugal mechanism is to be slipped on the shaft, proper running clearance established between spool and switch arms/buttons, and the centrifugal mechanism is to be attached to the shaft with two set screws.
  2. Standard mechanisms for 4 pole 60 hertz applications are stocked. Centrifugal mechanisms for other speeds (2, 6, or 8 pole - 60 hertz; or 2, 4, or 6 pole - 50 hertz) can be supplied as a special made to order.
