Magnetic Pole of the Stator

Magnetic pole of the stator

In considering the step operation, it is important to know the relationship between the current direction flowing in the stator winding of the motor and the direction of the stator’s magnetic pole.
Here we give an example of a bipolar type motor.
Let's look at the relationship between the current direction flowing in the stator winding and the direction of the magnetic pole.

Magnetic pole of the stator

Changing the current direction also changes the direction of the stator’s magnetic pole.
