Problems solved by technology

Its disadvantages are: in order to be able to accurately read the measured parameters at a certain moment, several people are often required to read the meter at the same time, the work efficiency is low, and the data obtained by playing around are the data in the same state
Not only that, due to the asynchrony of meter reading and various human errors in reading, recording, and calculation, the test data is scattered, the accuracy of the test results is low, and the repeatability is poor. Now this test method is basically eliminated.

Abstract

The invention discloses a smart self-starting permanent magnet motor, comprising a three-phase motor, wherein Y-delta type starting is employed by the three-phase motor; the three-phase motor comprises a shell, a front end cover, a rear end cover, a stator, a rotor, a fan and a fan cover; a master junction box is used for circuit wiring of the three-phase motor; a secondary junction box is arranged in the master junction box; and a test system is arranged in the secondary junction box and comprises a microcontroller, a temperature monitoring module, a vibration monitoring module, a noise monitoring module and a wireless transceiving module. According to the motor, the rotor is equipped with an asynchronous starting cast aluminium mouse cage winding and magnetic steel for synchronous operation; the motor can be started in a starting mode of a three-phase asynchronous motor and also can be operated in a working mode of a permanent magnet synchronous motor; the Y-delta type starting type is employed; compared with the existing permanent magnet synchronous motor, the motor has the advantage that the motor is simpler; the working efficiency is improved from 86% of the excising three-phase asynchronous motor to 95%; the thermal load of the stator is 70% that of the existing three-phase asynchronous motor; and the energy saving effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a self-starting permanent magnet motor. Background technique [0002] As the power of various equipment, electric motors are widely used in various industries such as steel, oil fields, coal, home appliances, and mechanical equipment. In our country, industrial power consumption accounts for 70% of the total power consumption, and the power consumption of the motor system accounts for 60% to 70% of the total industrial power consumption. With the increasing scarcity of energy, energy saving and consumption reduction has become an extremely urgent task facing the development of the international community, and the realization of energy saving and consumption reduction in the motor industry has a pivotal position in the entire work of energy conservation and consumption reduction. [0003] It has been hundreds of years since the electric motor came out. Scientists have invented and...
