Description

Technical Field

[0002] Asynchronous motors, as indispensable power equipment in modern industry, have operating efficiency and control performance that are directly related to the effectiveness and energy consumption of the entire production line. The operating principle of asynchronous motors is based on the law of electromagnetic induction. The rotating magnetic field generated by the stator interacts with the induced current in the rotor, generating torque to drive the motor to rotate. However, in actual applications, the magnetic flux (i.e., air gap flux) of asynchronous motors is easily affected by various factors, such as power supply voltage fluctuations, motor load changes, and changes in motor parameters (such as resistance and inductance) with temperature or time. These factors can lead to unstable magnetic flux, which in turn affects the motor's output torque, efficiency, and stability. Traditional asynchronous motor control methods mostly use controllers for regulation, which can, to a certain extent, cope with the impact of magnetic flux changes.

[0003] When an existing control device is in use, it is generally provided with a connecting wire for reading information. However, the connecting wires on the existing control device are too long and easily tangled together, affecting subsequent normal use. In addition, the display screen for displaying numerical values ​​lacks protection, and the display screen is easily affected by external forces, causing damage. Utility Model Content
