What Is The Working Principle Of Electric Fan Motor?

The starting torque of the electric fan is 0, so a rotating magnetic field must be generated inside it to make the motor turn. Generally, a starting winding should be placed at the same time as the working winding. The distribution of these two windings in the motor should be spatially There is an angle. In this way, when currents of different phases are passed into the motor, a rotating magnetic field can be generated, so that the motor can be rotated. Generally, capacitor start or resistance split-phase start is used. It works according to the principle of electromagnetic induction. The current-carrying conductor moves under the action of force in the magnetic field. The coil is made of enameled wire with copper core or aluminum core. When a symmetrical current is passed into the stator coil, a rotating magnetic field is generated, and the rotor conductor cuts the rotating magnetic field. Under the action of the potential, the rotor conductor flows through the current, and the rotor current interacts with the rotating magnetic field, so that the rotor is driven by the electromagnetic torque generated by the electromagnetic force and rotates.
