The principle of a motor in an electric fan.
The electric fan motor uses 220v single-phase motor.
Single-phase constant current winding motor alternating magnetic field strength and weak to make changes with the law of string fixed space position called magnetic field alternating pulse magnetic field alternating pulse magnetic field solution two-phase rotating speed, rotating direction opposite rotating magnetic field rotating static two rotating magnetic field rotating production two equal, opposite-phase Torque make the co-rotating torque zero the motor rotation I use external force to make the motor rotate in a certain direction clockwise rotation and clockwise rotation to rotate the rotating magnetic field cutting magnetic line change; Rotating and counter-rotating rotating rotating magnetic field between cutting magnetic line balance break the total electromagnetic torque produced by rotating then zero rotation along the direction of rotation. In order to make the single-phase motor rotate, I must add the windings, the windings, the windings and the main windings must have a space difference of 90 degrees, the windings must be connected in series with the proper capacitance, and the current phase difference between the main windings is approximately 90 degrees, that is, the so-called phase principle, the current difference between the two windings is 90 degrees, the current flows into the two space difference of 90 degrees, the windings generate a two-phase rotating magnetic field.
