The run capacitor also provides running torque when the motor is up and running. The operation of the potential relay is based on the increase in back-electro-motive force (back-EMF) or a bucking ...

Often, a simple control scheme using a microprocessor can allow manufacturers to use lower starting torque compressors without the use of a hard start kit to operate their ice machines. Before the ...
