Components and Configuration
The stator is typically fixed to the motor's end housing, while the rotor is attached to the motor's output shaft.
The stator windings usually have six terminals, with two dedicated to the excitation signal input, which is a sinusoidal electrical signal (10 kHz) provided by a control unit to supply the excitation current.
The remaining terminals serve as the return windings, generating induced electromotive force as the motor rotates, typically producing a sine and cosine signal envelope.
Working Principle
Similar to conventional transformers, the variable reluctance resolver operates based on electromagnetic induction. The key difference lies in the variable relative position of the primary and secondary windings with respect to the rotor's angular displacement. This results in an output voltage that changes in accordance with the rotor's angle, maintaining a specific functional relationship.
Applications in Electric Vehicles
Variable reluctance resolvers are widely used in electric vehicles for position and speed sensing in various components, such as:
Position sensors for drive motors and generators.
Position sensors for electric power steering motors.
Measurement of fuel valve angles.
Advantages
Excellent processability and large relative displacement.
High reliability and low cost.
These attributes make them particularly suitable for electric vehicles.
