Magnetic field control system for alternating current synchronous motor and control method thereof

Abstract

The invention discloses a magnetic field control system for an AC synchronous motor and a control method thereof, relates to the technical field of motor magnetic field control, solves the technical problem that motor parameters cannot be accurately analyzed before the motor magnetic field is controlled in the prior art, analyzes the magnetic field of the surrounding environment of the motor, improves the accuracy of magnetic field detection in the motor, and improves the reliability of the motor. Meanwhile, the running state of the motor can be accurately analyzed, the situation that the control of the motor is reduced due to the fact that the peripheral magnetic field influences the magnetic field of the motor is prevented, the running cost of the motor is indirectly improved, and the running efficiency of the motor is reduced; by analyzing the state of the magnet in the motor, whether the magnetism of the magnet is saturated is judged, whether the specification of the motor is suitable for the current scene is detected, the working efficiency of the motor is improved, and the problems that the service life of the motor is shortened and the working efficiency of the motor is reduced due to unreasonable matching of the motor are prevented; the magnetic field is controlled according to the operation requirement of the motor, and the high efficiency of motor operation is improved.

Description

technical field [0001] The invention relates to the technical field of motor magnetic field control, in particular to a magnetic field control system for an AC synchronous motor and a control method thereof. Background technique [0002] Synchronous motors, like induction motors (ie asynchronous motors), are a commonly used AC motor. Synchronous motor is the heart of the power system. It is a component that integrates rotation and static, electromagnetic change and mechanical motion, and realizes the transformation of electrical energy and mechanical energy. Performance has a huge impact. Motors are also critical in the field of device control, where the control of the magnetic field within the motor is also increasingly important. [0003] However, in the prior art, it is impossible to determine the influence of the surrounding magnetic field on the motor, resulting in low and inaccurate magnetic field control; before the magnetic field control, it is impossible to accura...
