What is a drive motor resolver?

The drive motor resolver is an analytical tool for the operating principle of the motor. It is used to analyze the changing laws of the electromagnetic field when the motor is running. It consists of two parts: a stator and a rotor. The windings on the rotor and the windings on the stator have equal proportions of turns. Through the power supply of the AC power supply, the rotor magnetic field rotation caused by the AC electromagnetic field can be formed.

The role of the drive motor resolver

The drive motor resolver is mainly used for the research and analysis of the operating principles of the motor, and can help people understand the changing laws of the motor's magnetic field and the operating mechanism of the motor. At the same time, its existence also facilitates troubleshooting and maintenance of the motor.

The principle of the drive motor resolver

The principle of the drive motor resolver is relatively simple. A coil with N turns is passed through an external power supply with an alternating voltage U. The flow of magnetic flux in the electromagnet causes the current in the coil to change accordingly. Therefore, the magnitude of the current in the coil that changes with time t can be expressed as i(t), and the change in the magnetic flux in the magnet with time t can be expressed as is Φ(t).

Advantages of drive motor resolver

The drive motor resolver has the advantages of simple operation, strong analytical ability, and reliable data, and can realize objective and local perception of the analysis of the motor operating principle.

Application scope of drive motor resolver

Drive motor resolver can be used in the fields of research on motor operating principles, motor fault diagnosis and repair, motor performance optimization and other fields, and is widely used in electric power , machinery, metallurgy, chemical industry and other industrial fields.

Drive motors are one of the most widely used types of motors in modern industry, and drive motor resolvers are one of the effective ways to improve motor efficiency. The function of the drive motor resolver is to convert the DC power of the motor to be driven into AC power to cope with different load needs. This article explores the principles of drive motor resolvers and their advantages.

The principle of driving a motor resolver can be simply summarized as follows: when the motor is running, signals are transmitted through the resolver so that the motor can operate under different loads. The transformer itself uses a dense iron core, which can improve the electromagnetic induction effect and thereby improve the efficiency of the motor. By using a drive motor resolver, it can not only improve motor efficiency, but also extend the life of the motor, reduce the number of maintenance times, and reduce maintenance costs.

Not only that, the drive motor resolver can also effectively reduce the noise of the motor and improve the stability of the drive motor. Compared with the traditional motor drive method, the drive motor resolver is more convenient and flexible to use and can be adjusted according to different working environments and load requirements. This makes drive motor resolvers widely used in modern industrial production.

In short, the drive motor resolver is an extremely important way to drive the motor, which can improve motor efficiency, reduce noise, improve stability, extend life, and reduce maintenance costs. In modern industrial production, the use of drive motor resolvers has become an increasingly common choice.
