PSD5XX – Application Note 042
Stepper Motor
Operation
(Cont.)
The stator windings in a Hybrid stepper motor are distributed in 90-degree quadrants
around the motor case. See Figure 1 for the phase winding distribution of the hybrid motor.
Different methods are used for the excitation of a stepper motor. In this application a bipolar
drive circuit is used for the power stage. The motor windings are connected 90 degrees
apart such that the stepper motor looks like a two-phase motor. In this case there are four
motor leads to be powered from the amplifier stage. Each phase of this stepper motor is
powered by an H bridge. Figure 2 shows a typical H bridge that drives a stepper motor and
Figure 3 illustrates the driving waveforms.
