The structure of the permanent magnet wiper motor: electric drive (also called rotor), magnet (stator), brush, vortex rod, turbine, automatic return device (copper ring and contacts).
When the permanent magnet motor is working, a counter electromotive force is generated in the armature (rotor) at the same time, and its direction is opposite to the direction of the armature current. To make the motor rotate, the applied voltage must overcome the effect of the back electromotive force. When the motor speed increases, the back electromotive force increases. Only when the external voltage is equal to the back electromotive force, the armature speed can be stable.
When the switch is in the L position (low speed), the current flows in through the brush B1 and flows out through the brush B3. At this time, the effective number of windings through which the current passes is 4 + 4. The motor works at low speed. When the switch is in the H position (high speed), the effective number of current through The number of windings is 3+3, and the motor works at high speed.
Ordinary wipers have five and four wires, one positive pole, one negative pole, one return, two motor wires, one high speed, one low speed. The four wires are missing a negative pole, and the motor body is grounded.
There are two motor wires, one high speed and one low speed. The gap gear and low speed gear share the same wire. The remaining three wires are for the return plate. When the iron piece on the return plate is negative, the return line is the negative pole. When the iron piece is positive, the return line is the positive electrode, and when it is in the initial position, the return line is the negative electrode. As long as it does not return to the initial position, the iron piece is the positive electrode, and the return line is also the positive electrode. At this time, the positive electrode on the return line will pass by. The switch continues to supply the motor until it returns to the initial position and the return line becomes negative. At this time, the motor stops
