A PM stepper motor has six poles and a bipolar supply (i.e., the current into each coil pair can be either positive or negative). Figure 18.9 depicts a four-pole stepper motor as an example; the motor described in this problem has two additional poles. The spacing between the poles is uniform. Determine the size of the smallest achievable step in degrees.
