The accuracy, reliability, and durability of motor control systems are crucial in industries such as industrial automation, automotive, aerospace, and medical equipment. Resolvers play a vital role in achieving these characteristics by measuring the position and speed of the rotor. By providing continuous analog feedback, resolvers improve the accuracy, reliability, and durability of the system, enabling smoother and more precise control of motor speed and position.
Advantages:
1. Simple structure, sensitive operation, and reliable performance: It has low requirements for environmental conditions and can work normally even in high-temperature and dusty environments.
2. Large output signal amplitude and strong anti-interference ability: It can operate stably in complex electromagnetic environments.
3. Can completely replace photoelectric encoders: It has wide applications in angle and position detection systems.
Application Areas
1. Servo Control Systems: Used to measure the angular displacement and angular velocity of rotating objects, enabling precise position control.
2. Robotic Systems: Provides precise angle feedback for robot joints, ensuring the accuracy of robot movement.
3. Automotive Industry: In electric vehicles, rotary transformers are used as position and speed sensors, providing critical information for motor control. Furthermore, in hybrid vehicles, rotary transformers also play an important role in detecting the rotational speed of the electric motor.
4. Industrial Automation: In equipment such as CNC machine tools, injection molding machines, elevators, and robotic arms, rotary transformers are used to achieve precise measurement of angular velocity and position.
5. Transportation Sector: Rotary transformers are also widely used in areas such as railway transportation, agricultural and construction equipment, buses and heavy trucks, golf carts, and low-speed electric vehicles.
6. Aerospace and Military Fields: Due to their high reliability and precision, rotary transformers are widely used in angle and position detection systems in the aerospace and military fields.
How to choose RESOLVER
Based on the functional relationship between the output voltage and the rotor angle, rotary transformers are mainly divided into the following three categories:
1. Sine or cosine rotary transformers: The functional relationship between their output voltage and rotor angle is a sine or cosine function.
2. Linear rotary transformers: The output voltage is linearly related to the rotor angle. Linear rotary transformers are further divided into salient-pole and non-salient-pole types based on their rotor structure.
3. Proportional rotary transformers: The output voltage is proportional to the rotor angle.
According to other classification methods
• By application: Rotary transformers can be divided into computational rotary transformers and data transmission rotary transformers.
• By their relative position and specific function in the angular calculation, related transformation, and signal transmission systems they constitute: Rotary transformer transmitters, resolver differential transmitters, and resolver transformers, etc.
• By structure: Rotary transformers can be divided into contact type and contactless type (with or without slip ring brushes).
• By rotor rotation angle limitation: Rotary transformers can be divided into finite angle and infinite angle types.
• By number of pole pairs: Rotary transformers can be divided into single-pole and multi-pole types.
