A driving circuit of a brake disk grinder is provided to prevent overload of a DC motor by controlling an AC motor and the DC motor through a control part according to power supply to a processing unit. A brake disk(1) is rotated by an AC motor(220) installed in a body(200). A vice(431) is moved by a DC motor installed to a processing unit(400) to grind a surface of the brake disk. A control part(500) is installed on one side of the body to control the AC motor placed in the body and the DC motor mounted on a back and forth moving member(420) of the processing unit. A control part is installed on the control part by forming a circuit on a PCB(printed circuit board) to apply power to the AC and the DC motors, to output work completion sound, and to change the power supply. The control part includes a case(501), a power supply switch(510), a control switch(520), a switching unit(530), a power supply socket, a speaker, a supply socket, and a fuse. |
