Three-phase brushless motor control circuit
Shown is the schematic diagram of the three-phase brushless motor control circuit of the combination of MC33035 P and MC33039P . MC33035 P is the main
motor control circuit . It outputs 6 drive signals respectively , which are amplified by the output amplifier to drive the stator coil of the three-phase motor. There are three Hall ICs in the
motor. The Hall element is a magnetic induction element, which is integrated with the IC to form a magnetic field sensor. Each Hall IC
has 3 pins, one is the ground terminal, one is the power supply terminal, and the other is the output terminal. When the magnetic field acts on the Hall IC, there will be a signal
voltage output.
