Resolver sensors are a type of position sensor that detect the angular position of an object. They are used in various applications, including robotics, aerospace, and industrial machinery. This article will explore the workings and benefits of resolver sensors, as well as their applications and market trends.
A resolver sensor is a type of rotary position sensor that detects the angular position of an object. It consists of a stator and a rotor, with the rotor mounted on a shaft that rotates within the stator. The stator has two winding sets, the primary and secondary, which are arranged at right angles to each other. As the rotor rotates, it generates a voltage that is proportional to its angular position.
The resolver sensor works on the principle of electromagnetic induction. When an AC voltage is applied to the primary winding, it generates a magnetic field that induces a voltage in the secondary winding. The amount of induced voltage depends on the angle of the rotor. By measuring the induced voltage, the angular position of the rotor can be determined.
There are two main types of resolver sensors: absolute and incremental. Absolute resolvers provide a unique output for each position, while incremental resolvers provide a change in output for each position. Absolute resolvers are used in applications where the position must be known at all times, while incremental resolvers are used in applications where the position can be determined by counting the number of increments.
Resolver sensors are known for their high accuracy and precision. They can detect angular position with an accuracy of up to 1 arcminute, which is much higher than other types of position sensors. This makes them ideal for applications where precise position control is required.
Resolver sensors are highly durable and reliable. They are designed to withstand harsh environmental conditions, such as extreme temperatures, humidity, and vibration. This makes them suitable for use in applications where other types of sensors may fail.
Resolver sensors are used in a wide range of applications, including robotics, aerospace, and industrial machinery. In robotics, they are used to detect the position of robot joints and control their movement. In aerospace, they are used to detect the position of aircraft control surfaces and ensure safe operation. In industrial machinery, they are used to detect the position of rotating parts and ensure accurate positioning.
The resolver sensor market is expected to grow significantly in the coming years. The increasing demand for high-precision position sensors in various industries, such as aerospace, automotive, and industrial automation, is driving the growth of the market. The rising adoption of resolver sensors in robotics and medical applications is also contributing to the market growth.
