Brushless DC Motor Controller

MC33033, NCV33033

Figure 37 shows a three phase, three step, half wave motor

controller. This configuration is ideally suited for

automobile and other low voltage applications since there is

only one power switch voltage drop in series with a given

stator winding. Current flow is unidirectional or half wave

because only one end of each winding is switched. The stator

flyback voltage is clamped by a single zener and three

diodes.
