Motor Run & Motor Start Capacitors

Electric motors exploit the interaction between two magnetic fields for rotating a shaft. The stator windings generate one of the fields, and the rotor windings provide the other. In some DC motors, permanent magnets replace one of the windings, while the commutator, whether brushed or brush-less, changes the direction of the current in the other winding to continuously alter the interaction between the two magnetic fields to allow the motor to rotate. In three-phase AC motors, the interaction between Read more [...]

Motor Start Capacitors vs Motor Run Capacitors

We are often asked about the difference between the two different types of motor capacitors: motor run and motor start. Here are the basic differences between the two: Motor Start Capacitors The primary purpose of a motor start capacitor is to briefly increase the motor starting torque as well as to allow a motor to be cycled on and off very quickly. It operates in the circuit by staying active long enough to allow the motor to be brought to 3/4 of it's full capacity. It is removed at that point Read more [...]
