Rotary connector with steering angle verification function for car's steering wheel

摘要

The rotary connector has a rotor core (12) rotating synchronously with the steering wheel (10), an annular winding (13) mounted on the rotor core, a stator core lying opposite the rotor core via an air gap, and an annular winding (6) located on the stator core. Along the coils, a surface of the rotor core and stator core stands opposite one another, are alternating projections and recesses around the periphery. Two or more pairs of windings are located on the rotor and stator cores. A tooth element having projections and recesses is located along the winding pair.
