Drive circuit of magnetic coil to slowly rotate
.But if the fed low frequency to the motor driver circuit to make a magnetic rotating speed. From the experiment if magnetic rotating cutting electrical coils at top speed is the frequency 243 Hz gain speed should bake 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
