Motor is the common name of motor. Its working principle is based on the principle of electromagnetic induction. The current-carrying conductor moves under the action of force in the magnetic field. The coils you mentioned are made of enameled wires with copper or aluminium cores. They are called stator coils. They are basically enameled wires with copper cores and are symmetrically arranged in the stator slot. The rotating part is called rotor and some aluminium is used. Rotor windings are made up of strips. When three-phase symmetrical current is introduced into the stator coil, a rotating magnetic field is generated. Rotor conductor cuts the rotating magnetic field to generate induced potential. Under the action of electric potential, the rotor conductor flows through the current and the rotor current interacts with the rotating magnetic field, so that the rotor is rotated by the electromagnetic torque generated by the electromagnetic force. Here I am talking about the three-phase motor. Since the starting moment of a phase motor is 0, a rotating magnetic field must be generated inside the motor to make the motor turn up. Generally, a starting winding should be installed at the same time as the working winding is installed. The distribution of the two windings in the motor should have an angle in space. In this way, the rotating magnetic field can be generated by introducing different phases of current into the motor, so that the motor can turn up. Come on. Start with capacitor or resistor separately.
