Core Materials
Magnetic Core Material: The heart of the transformer, typically made from ferrites, known for high magnetic permeability, low hysteresis loss, high saturation magnetic flux density, and excellent stability and longevity. Common materials include silicon steel sheets and aluminum-nickel-cobalt magnets.
Winding Material: Crucial for the performance of the transformer, winding materials should have good electrical insulation, high conductivity, thermal stability, and corrosion resistance. Commonly used materials are copper wires and aluminum oxide ceramics.
Rotor Material: As the moving part, rotor materials should be hard, wear-resistant, and have good electrical and magnetic conductivity with a low coefficient of friction. Common rotor materials include copper and aluminum.
Working Principle
The operation of a variable reluctance resolver is governed by simple magnetic laws. The rotation of the rotor generates a magnetic field, inducing a change in the magnetic flux through the reluctance rings, which in turn induces a varying electromotive force (EMF). This EMF generates a current that is transformed into an output potential, the characteristics of which are determined by the rotor's speed and position.
Application Scenarios
Power Systems: They convert high voltages to lower voltages for the safe operation of other equipment.
Control Systems: Used for feedback control to regulate and optimize system performance.
Sensors: Convert physical quantities such as angle, position, and velocity into electrical signals.
Advantages in Motion Control
Reliability: Unmatched in harsh environmental conditions, offering excellent durability.
High-Speed Operation: Capable of operating at very high speeds, compared to optical encoders limited to 3,000 rpm due to the frequency response of photoelectric devices.
Absolute Value Signal Output: Convenient for direct angle measurement without the need for initialization.
Use in Electric Vehicles
Modern electric vehicles often use permanent magnet synchronous motors, where the "position sensor" is vital for detecting the exact instantaneous position of the motor rotor, which is crucial for the motor's power supply system.The electric vehicle's drive control circuit, including the inverter controlled by the vehicle's ECU, relies heavily on precise signals from the position sensor, commonly a variable reluctance resolver.
