In this thesis the motor control with a Bedini Microcontroler เครื่องประกอบด้วย series, motor drive circuit 3 series, both 3 series. Controlled by micro controller. Use radius size and magnetic 10 cm have high 4 cm, wide, 2 cmThick 0.5 cm has the working principle by micro controller to create the frequency the frequency to pay with วงจรขับ motor. In order to control the speed of the magnetic disk). The micro controller can generate a frequency multiple values.Experiments found that if Microcontroler when paying high frequency into the coil drive circuit to make a magnetic rotating slowly. But if the fed low frequency to the motor driver circuit to make a magnetic rotating speed.The frequency 243 Hz gain faster around the 1800 rpm, the bit 0.279 N.m voltage obtained from the generator set 15 Vac current 600 mA. Magnetic spin and slowest frequency 1.016 KHz gain faster around the 480 rpm, the bit 0.074 N.m pressure electricity from the generator set 13 Vac. Current, 600 mA
