The working principle of three-phase asynchronous motors is based on the principle of electromagnetic induction. When the stator winding passes through three-phase symmetrical alternating current, a rotating magnetic field is generated between the stator and rotor. This rotating magnetic field cuts through the rotor winding, generating induced electromotive force and current in the rotor circuit. The current of the rotor conductor is subjected to force under the action of the rotating magnetic field, causing the rotor to rotate.

AC motor is currently the most commonly used type of motor in coal mines. It is mainly divided into two categories: induction motors and synchronous motors. Induction motors are commonly used in low-power compensation equipment, ventilation equipment, conveying machinery, and other occasions. They have the characteristics of high starting torque, simple structure, and high reliability. Synchronous motors are mainly used in heavy-duty equipment such as electric pumps, fans, and compressors in coal mines. Their characteristics are stable operation, good speed regulation performance, and high power factor.

A three-phase asynchronous motor is a type of induction motor that relies on simultaneously connecting a 380V three-phase AC current (phase difference of 120 degrees) for power supply. Due to the fact that the rotor and stator of a three-phase asynchronous motor rotate in the same direction and at different speeds, there is a slip rate, so it is called a three-phase asynchronous motor. Next, the Yongzhuan editor will take you to learn about the relevant knowledge of three-phase asynchronous motors.

When it comes to intelligent manufacturing, it is necessary to mention the core of industrial automation equipment - servo systems. What is a servo system? A servo system is a general term for equipment that enables machines to perform movements such as displacement, speed, and torque based on instructions. It consists of a controller, servo drive, servo motor, and an encoder. Simply put, "servo" is synonymous with "precise control" of machines, which determines the accuracy and response speed of automated machinery.

1. The starting equipment of the motor should be cleaned of external dust and dirt in a timely manner, the contacts should be wiped, and all wiring parts should be checked for burn marks and the grounding wire should be in good condition.

Electric motors, a widely used power conversion device in industry and daily life, are now undergoing a revolution. The emergence of new motor materials has opened up new doors for energy efficiency improvement, while also providing strong technical support for reducing energy consumption.
