Can AC motors use direct current?
DC motor is also on the brush structure changing direction of manufacturing power changing magnetic field, electromagnetic force and drag on the rotor, the AC motor for AC power supply design, no directional structure, once the direct current, stator winding equivalent inductance and resistance, inductance in the DC power supply and the equivalent circuit, the resistance heating to a certain extent possible burn.
Ordinary asynchronous AC motors are not allowed.But some live brush AC motors are slightly modified and can be powered by direct current.
Only stepper motors with drivers can use DC for special purposes. But it hurts motors very much. The rest can not, junior high school common sense.
AC motors use direct current, because the motor will not rotate, it will burn the coil in a short time.
The DC motor is divided into two exciting modes: series excitation and shunt excitation. The series excited DC motor can be used in both DC and DC as long as the voltage is suitable. Shunt excited DC motors can only be powered by dc.
