About Wiper Motors

The windscreen wiper mechanism is powered by a BMW wiper motor. Wipers are a standard safety feature in cars and can be positioned on both the front and rear windscreen of the car. Most cars have two wipers on the front windscreen, one on the driverside and one on the passengerside. The driver needs to look through the front windscreen to see the road ahead, and through the back windscreen to see the traffic behind, so it's imperative that the windscreens are in perfect, clean condition.  The BMW wiper motor provides the power needed to make the windscreen wipers move, so it has an important role to play in keeping the windscreen in a safe, clean condition. The wiper consists of a wiper arm and a wiper blade. The wiper blade is made from rubber and as the arm is powered by the wiper motor to move across the windscreen, the rubber blade moves the water and debris from the surface of the windscreen, clearing the screen to enable a clear vision of sight for the driver.  

The wiper motor and linkage mechanism is located beneath the bonnet, generally concealed by a plastic scuttle panel. 

The electric wiper motor consists of a cylinder referred to as the rotor or armature. This is the rotating part of the motor and it houses all of the components that work together to make up the motor. Surrounding the rotor are copper coils of wire which act as the conductors. When the wiper motor switch is activated by the driver via the controls on the wiper stalk switch, this sends an electric current to the motor, and the copper winding picks up this current causing the electricity to move through the wiring. The electricity moving through the copper wire creates a circular magnetic field. It's this magnetic energy which generates the force to power the cylinder and makes it spin. The spinning cylinder creates the energy needed to power the motor which in turn powers the wiper mechanism. Driven by the BMW wiper motor, the wiper linkage is moved back and forth by cams. The wiper motor sources its electrical power through direct current from the car's battery. Often an electric motor will contain carbon brushes that work to move the electricity from outside the motor to the rotating copper winding housed in the centre of the motor. 

Common failures with the wiper motor occur when the winding becomes shorted. These copper conductors can overheat causing the winding to short circuit. The carbon brushes in the motor are also put under a great deal of friction, and will eventually burn out causing the wiper motor to malfunction. When the windscreen wiper motor needs replacing, buying the BMW wiper motor will ensure you get a part that's completely compatible with the make and model of your car.

BMW trivia

• The BMW 3.0CSL was sold in the 70s and had the unusual addition of a spoiler that was kept in the boot. The owner could install it if they wanted to, but BMW couldn't sell the car with the spoiler attached because of road laws!
• The BMW company was founded way back in 1916 and originally manufactured engines for planes. High demand for plane engines during WWI was good news for BMW, but they carried on making plane engines right up until 1945.
• The main headquarters for BMW in Munich is designed and shaped to look like car parts. There was a whole new 'four-cylinder' building added on in 1973, and there's definitely the look of an engine about the architecture.
• The famous German pilot, the Red Baron, called BMW engines the 'greatest in the world' and ‘the best engine in the war’.
• One of the reasons older BMWs keep their value is because it's easy to get spare parts for even the oldest models. That's because BMW has carried on making car parts, even for cars that were built in WWII.
