1. A motor driving device comprising:

  • a rectifier having at least one input terminal, a first output terminal and a second output terminal, the input terminal of the rectifier electrically connected to a power source;

    a resistor having a first terminal and a second terminal, the first terminal of the resistor being in direct contact with the first output terminal of the rectifier;

    a capacitor having a first terminal and a second terminal, the first terminal of the capacitor being in direct contact with the second terminal of the resistor, the second terminal of the capacitor being in direct contact with the second output terminal of the rectifier;

    an electronic switch connected to the resistor in parallel, wherein one end of the electronic switch is in direct contact with the first terminal of the resistor, and another end of the electronic switch is in direct contact with the second terminal of the resistor; and

    a driving circuit having a first input terminal, a second input terminal and at least one output terminal, the first input terminal of the driving circuit being in direct contact with the first terminal of the resistor, the second input terminal of the driving circuit being in direct contact with the second terminal of the capacitor, the output terminal of the driving circuit being in direct contact with a motor.
