The classification of Wannan motor DC motor main excitation mode

The excitation mode of DC motor is the problem of how to establish the main magnetic field in the field of excitation winding, which generates the excitation flux. According to the different excitation mode, the DC motor can be divided into the following types:

1 compound excitation DC motor

The compound wound DC motor has two excitation windings, which are excited and excited. In the same direction as the magnetic flux generated by the series wound windings and the magnetic flux potential generated by the shunt winding, the winding is also called a product complex. If the direction of the two magnetic flux is opposite to that of the DC motor, the difference is called a DC motor.

2 he Shunt DC motor

There is no connection between the field winding and the armature winding, and the DC motor, which is supplied by the DC power supply to the field winding, is called a Shunt DC motor. 3 Series Shunt DC motor

The field winding of the series Shunt DC motor is connected with the armature winding in series, and then connected to the DC power source. The excitation current of the DC motor is the armature current.

3 Series Shunt DC motor

The field winding of the series Shunt DC motor is connected with the armature winding in series, and then connected to the DC power source. The excitation current of the DC motor is the armature current.

4 and Shunt DC motor

And the shunt wound DC motor excitation winding and the armature winding are connected in parallel, as a shunt generator, motor terminal voltage excitation winding power supply; as a shunt motor, excitation winding and the armature sharing the same power, from the performance about separately excited DC motor with the same.
