Wheel Speed Sensor: Description and Operation
Consists of a sensor and a rotor. The sensor is attached to the knuckle on the front wheels and to the axle shaft bearing holder on the rear wheels. The
rotor is press-fit in the axle shaft. The flux generated from electrodes magnetized by a magnet in the sensor varies due to rotation of the rotor, and the
electromagnetic induction generates alternating voltage in the coil. This voltage draws a "sine curve" with the frequency proportional to rotor speed and
it allows detection of wheel speed.
