What are the meanings of stepper motors unipolar and bipolar? What are the differences between the four wire bipolar motors?
Bipolar: Bipolar not only turns several windings in turn, but also changes the direction of the current in the windingSuch as four wire bipolar motors, there are two windings, A and B,The ends of A winding are A1 and A2 respectively, and the ends of B are B1 and B2. respectivelyMode of operation: A1, A2-----B1, B2-----A2, A1-----B2, B1-----A1, A2-----
Unipolar, does not change the direction of the winding current, but only a few windings in turn cycle power,For example, four phase motor, there are four windings, namely: ABCD, there are two modes of operation:
