The circuit breaker AC/DC motor is a kind of series motor which can be supplied by AC power or DC power, which is called universal motor. It is the series excitation powered by AC and DC.
In order to make the circuit breaker AC/DC motor can adapt to AC operation, the whole magnetic circuit system will be made by the lamination. In this way, the vortex can be reduced.
In the use of the circuit breaker AC/DC motor, in addition to the excitation winding F and commutating pole winding FD, the compensating winding Fs should be added on the stator. In this way, when the AC operation is limited, the armature winding can produce a relatively large reactance voltage drop and improve commutating.
The circuit breaker AC/DC motor is the improvement of DC series motor. Because of this, it can be run as a DC motor. When it runs as the DC motor, the magnetic flow and armature current direction remain unchanged, and the direction of electromagnetic torque remains unchanged. When it runs as the AC motor, the magnetic flow and size and direction of the armature current are changing constantly.
When using the circuit breaker AC/DC motor, the direction of the torque will remain unchanged. The mechanical characteristics of the circuit breaker AC/DC motor are similar to those of DC series motor. The starting torque will be large, and the power supply will be more convenient.
