Basic circuit of the motor

Single chip microcomputer STM32L151CCU6

Probe current voltage pin 420*4450 head diameter 5.0 over current current and voltage pin

Mobile phone crystal 3.2*2.5mm 3225 26M (26.000MHZ) 7.5PF 10PPM 20PPM 30PPM

As shown in the figure, when the "Operation" button switch is pressed, the motor starts to run. Usually, the "stop" button switch is used to stop the motor. In the event of an accident, the motor reaches an overload state, and the sensor that detects the overcurrent is operated. Release the running state to avoid motor burnout.
