The flow and phase relationship of the driving circuit signal a

The flow and phase relationship of the drive signal and
    the connection relationship between the drive transistor circuit and the motor winding are shown in Figure (a). The control circuit
realizes cyclic on and off control through cross-control of six transistors , thereby continuously changing the direction of the current. At /o-fl time (0D-1200). The process
and phase relationship of its driving signal . When the transistors U+ and v- are turned on, the other transistors are turned off. The signal flow is that the power supply current passes through the positive terminal - U+ transistor - U
coil - V coil - v- transistor - R806 - negative terminal or arrived.
