Working Principle
The variable reluctance resolver operates on the principle of electromagnetic induction, similar to conventional transformers. However, the distinctive feature is the variable reluctance that changes with the relative position of the primary and secondary windings in response to the rotor's angular displacement. This change in reluctance induces a voltage in the secondary winding that varies with the rotor's angle, maintaining a specific functional relationship with the angle.
Applications in Electric Vehicles
Variable reluctance resolvers play a crucial role in electric vehicles for precise position and speed sensing in several key components:
Position sensors for drive motors and generators: They provide accurate feedback on the angular position of the motor shafts, which is vital for efficient motor control and power management.
Position sensors for electric power steering motors: These sensors ensure precise steering by accurately sensing the steering wheel's position and assisting the driver with the appropriate level of power assistance.
Measurement of fuel valve angles: In hybrid electric vehicles, resolvers can be used to measure the angles of fuel valves, contributing to optimal fuel injection and combustion.
Advantages
Variable reluctance resolvers offer several advantages that make them well-suited for use in electric vehicles:
Excellent processability and large relative displacement: They can handle large angular displacements and are easy to integrate into various systems within the vehicle.
High reliability and low cost: Known for their robustness and cost-effectiveness, these resolvers provide a reliable solution for position and speed sensing with minimal maintenance requirements.
