Variable-frequency speed-adjusting three-phase asynchronous motor

Abstract

The invention discloses a variable-frequency speed-adjusting three-phase asynchronous motor. The motor comprises a machine base, the inner side of the rear end of the machine base is provided with a fixing ring used for fixing a stator iron core, the fixing ring is provided with a temperature sensor, the front side and the rear side of the machine base are provided with a front end cap and a rear end cap respectively, a rotor is fixed in the machine base, bearings are disposed at the two ends of a rotor shaft respectively, bearing supporting bases are arranged on the front and rear end caps respectively, ventilation holes are formed in the front end cap and in the rear end cap, the rear side of the rear end cap is provided with a fan and a fan cover, a wiring box is disposed on the machine base, the wiring box is provided with a warning device, the upper end of the wiring box is provided with a fixing groove, an insulation plastic fixing layer is disposed in the fixing groove, a display screen is fixed to the insulating plastic fixing layer, the temperature sensor, the warning device and the display screen are connected with a control device in the wiring box, and the control device is connected with a timing module. The motor is simple in structure and reasonable in design, a user can conveniently know the temperature in the motor and the use time of the motor in time, and the user can be reminded when the temperature is too high.

Description

technical field [0001] The invention relates to the field of motors, in particular to a three-phase asynchronous motor with frequency conversion and speed regulation. Background technique [0002] The motor in the prior art tends to increase in temperature when it is continuously used for a long time, and the aging of the motor will be accelerated at a higher temperature for a long time. The motor in the prior art cannot let the user know the internal temperature of the motor and the temperature reached The time spent at this temperature. Contents of the invention [0003] In order to solve the above problems, the present invention provides a three-phase asynchronous motor with frequency conversion and speed regulation capable of displaying the internal temperature of the motor and recording the use time. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: [0005] The invention is a three-phase asyn...
