On this page, I will explain about the operation principle of stepper motor. There are many kind of stepper motors. Unipolar type, Bipolar type, Single-phase type, Multi-phase type... Single-phase stepper motor is often used for quartz watch. On this page, I will explain the operation principle of the 2-phase unipolar PM type stepper motor.In the PM type stepper motor, a permanent magnet is used for rotor and coils are put on stator. The stepper motor model which has 4-poles is shown in the figure on the left. In case of this motor, step angle of the rotor is 90 degrees.
Where is Source or Hex file??? Just another Indian bullshite! This ain't your work......
