Q:Is the motor of an electric tool the alternating current motor or the direct current motor?

The series motor is usually used. The series motor is connected in series because the stator and rotor windings are connected together, so when the current is reversed, the magnetic field is reversed, so the torque direction remains the same. However, according to this principle, the motor works at 180 degrees after the torque is gone, so even the AC motor, but also need to reverse, in order to work like a DC motor.The rectifier also needs to be rectified if it is operated under the direct current. The rectifier bridge is very small. On the circuit board, there are four diodes close together, mostly rectifier bridge
