Wiper motor: work, change and price

The wiper motor drives the wiper blade mechanism. It is an electric motor powered by your vehicle's battery. This device is required and must have Windshield washer fluid... When this motor is not running, the brushes will no longer work and this will obstruct your visibility.

💧 How does the wiper motor work?

The wiper system consists of two main components: electric motor и transmission gear... The first consists of an anchor, magnetic inductors и brushes fixed at the level of the armature collector.

The second has a screw with an armature end that transfers rotation to a larger gear, which increases the rotation speed. The current goes through two brooms one positive and one massive... So this is magnetic field strength which allows you to act on the armature winding and measure its importance.

Thus, the wiper motor can operate at several speeds:

• At low speed : mainly used during light rainfall. The magnetic field is at its maximum, therefore the engine idling speed;
• At medium speed : set when waterfalls are more important. The magnetic field strength is at medium strength to increase the engine speed;
• High speed : This is useful when water pipes or even hail falls on the windshield. The power goes through a third brush, which is off-axis. The strength of the magnetic field is very small so that the motor can rotate at a very high speed.

You can control this speed using teams are present at your dashboard or on the steering wheel, depending on the car model.

In addition, on the most recent cars, the wipers are automatically activated thanks to a sensor that detects rain, whether light or heavy, and adjusts the cleaning speed.

💡 How to check the wiper motor?

There are several ways to check the wiper motor. The most common is direct connection multimeter in ohmmeter position on the wiper motor wires under the hood of your vehicle.

In particular, they must be related to mass broom to check that the electrical current is being supplied correctly.

There are several signs that can alert you to wiper motor failure when using wiper blades, for example:

1. The wiper blades move more slowly than usual;
2. The wiper blades do not move at all;
3. The wiper blades only operate at one speed, even if control is switched;
4. The wiper blades stop in the wrong position;

If the wiper motor no longer works, it is time to replace it. Rather contact a professional car maker for a change.
