Alternator
This magnet wire-wrapped piece of equipment is constantly working to generate electricity as the engine is running. The belt-driven system spins stators and rotors so diodes can convert AC to DC current.
Power Mirrors
There are two DC motors, wrapped with magnet wire, built into a single housing, controlling this operation. One is designed to control the up/down motion, the other controls left/right -- while both are connected to the relays.
Relays
The communication system relies on magnet wire to help the car use electrical power in automating circuits on and off when activated.
Air Conditioning
Magnet wire allows motors in a belt-driven compressor to liquify freon. A control panel relay tells additional motors driving the blower fans to push the air back into the cabin.
Windshield Wipers
Wiper arms are moved by the unidirectional rotation of a motor -- wound with magnet wire –that controls a wiper transmission. Its motion moves the affixed blades to clean the windshield.
Power Seats
Using a motor -- wound with magnet wire controlled by a button -- a current along additional magnet wire in the electrical system relays a message to turn and move the seat.
Power Sunroof
Magnet wire is built into a small motor that either mechanically opens or closes the sunroof. The motor spins to push or retract rods that are connected to the roof.
Power Liftgate
Magnet wire links the control panel to activation sensors forcing the cylinder to fire its piston automatically lifting or closing when operated
Power Windows
A small motor that is attached to a worm gear operates the windows by turning its interlinking teeth inside a spiral, moving the window up or down depending on the relay.
Power Doors
A small electric motor turns a series of spur gears that drives a rack-and-pinion gearset on an actuator rod. The rack converts rotational motion to linear motion and operates the lock.
Steer Assist
Electric motors wound with magnet wire have replaced hydraulic steering controls recently. A study by Chevrolet has shown this shift has improved fuel economy by 2.5%.
ABS
Controlled electronically through an actuator, ABS systems rapidly activate the brakes to keep the car from skidding. Sensors also detect skid conditions and communicate back to the car through its relays and computer systems.
Starter
Starter motors are powered by the battery and require a high electric current to pass through magnet wire in order to turn over the engine.
Traction / Stability Control
Magnet wire is connecting the accelerator, brakes, and wheels to the on-board computer. It communicates electrically to limit the power delivery and help eliminate wheel slippage.
Horn
Operating off a three-wire wire connection to a single solenoid with a metal diaphragm, the horn sounds when positive voltage through the relay is applied. Pressing the steering wheel short-circuits a grounded wire allowing the voltage to pass.
Ignition Coil
Inside the coils are thousands of tiny copper windings that receive a 12V charge before converting and providing between 20,000 to 30,000 volts and sending it to the distributor.
Essex Solutions is the largest global manufacturer of magnet/winding wire that supplies the major automotive and non-automotive original equipment manufacturers (OEMs) and Tier 1 suppliers that are building electric motors, transformers, motion devices, and more.
