With the start capacitor out of the circuit, the motor becomes a permanent split capacitance (PSC) motor in the running mode only. Next month: Tomczyk will cover potential relay rating specifications ...

When a capacitor short-circuits, the winding in the motor may burn out. When a capacitor deteriorates or opens, the motor often does not have the proper torque to easily start. If the motor is ...

The motor’s rotor will now start to rotate or turn. In Figure 3, notice that the run and start capacitors are wired in parallel to one another, yet both are in series with the start winding. The ...

A perusal of the NEMA document shows that capacitor-start and capacitor-run fractional horsepower motors will be affected by the new standards which in general, will become effective on March 9, 2015.
