Motorcycle Speedometer Work

Eddy-Current Speedometers

As the solenoid spins, it creates rotating electronic currents called eddy currents in the speedometer Mug. As the eddy currents proceeding, they constitute a Attractive universe in the Mug.

How it Works

The Attractive field in the cup is attracted to the field in the magnet. A inconsiderable Mug called the speedometer Mug surrounds the electromagnet. The Mug is attached to the speedometer rotate, which is attached to a spring.

Eddy Currents

When the rotate spins, it makes the cable spin, which makes the magnetite spin.Eddy-current speedometers keep been used in cars, trucks and motorcycles in that the early 20th century. In motorcycles, a Supple cable runs up from the rotate to the speedometer. At the speedometer, it is attached to a electromagnet.

As the magnet spins, it pulls on the cup. The faster the magnet spins, the greater the pull. The spring attached to the cup pulls back. When the cup is resting, the spring holds the speedometer in place at zero. As the wheel makes the magnet spin faster, it turns the dial further and further, overcoming the resistance of the spring. As the car motorcycle slows down, the spring pulls the needle back toward zero.
