Brushless DC motor control circuit MC33035 and MC33039 uses a combination of the control circuit is shown in Figure A typical brushless DC motor control circuit, which is mainl
y driven by the motor control chip MC33035 and MC33039 brushless motor adapter and field effect transistors and other parts of the drive circuit. At work. MC33035 output channel 6 I-WM signals to drive the motor driving circuit 6 by a field effect transistor. It is seen from six field effect transistor bridge circuit. Outputs are connected to the three-phase motor winding. Three-phase current in the windings sequentially changed according to the law, to form a rotating magnetic field, the rotor of the drive motor continuously rotates.
