Description

Technical Field

[0001] The utility model relates to the technical field of asynchronous motors, in particular to a three-phase asynchronous motor with a fault monitoring structure. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It has a wide range of uses, especially in industrial production, where it has an irreplaceable position. A three-phase asynchronous motor is a type of electric motor that is powered by a 380V three-phase AC power supply. Since the rotor and stator rotating magnetic fields of a three-phase asynchronous motor rotate in the same direction but at different speeds, there is a slip rate, so it is called a three-phase asynchronous motor.

[0003] The existing three-phase asynchronous motor does not have a fault monitoring structure function during use, such as the three-phase asynchronous motor disclosed in application number CN202122967031.2. The existing three-phase asynchronous motor of this type does not have a multi-faceted fault monitoring structure when in use. The motor lacks real-time detection and has no fault monitoring structure. It is impossible to monitor its operating status and abnormal conditions in the working environment in real time, such as humidity, temperature, vibration, etc. The abnormality of these parameters is often a precursor to motor failure. If it is not discovered in time, it may cause the fault to expand and even cause a serious accident. In the absence of fault monitoring, the operating status of the motor can only be discovered by manual inspection. This method is not only inefficient, but also easy to miss problems, and it is impossible to achieve comprehensive and timely fault detection. Therefore, when the fault occurs for too long and is not discovered in time, it will increase the difficulty of maintenance and require more time and resources to repair, resulting in a waste of resources and an increase in maintenance costs.

[0004] Therefore, it is necessary to invent a three-phase asynchronous motor with a fault monitoring structure to solve the above problems. Utility Model Content

[0007] Preferably, smoke sensors are installed on both sides of the inner part of the outer shell, and the smoke sensors are inductively connected to the external fault monitoring structure. Monitors are installed on both corners of the inner top surface of the outer shell, and the monitors are connected to the external PC in real time.

[0008] Preferably, two sliding doors are provided and are respectively located on both sides of the opening end of the outer shell.

[0009] Preferably, sliding blocks are installed on both sides of the surface of the sliding door that is in contact with the outer shell, and sliding grooves that are slidably matched with the sliding blocks are provided on the upper and lower sides of the front side of the outer shell.

[0010] Preferably, the fault monitoring structure includes a base, a moisture sensor and an alarm, the base is located above the rear side of the outer shell, a moisture sensor is installed below the front side of the base, and both ends of the base are inductively connected to the alarm.

[0013] Preferably, the induction plate is fixed to the bottom of the motor body, the bottom surface of the induction plate is mounted on the inner bottom surface of the outer shell, and a vibration sensor is arranged inside the induction plate.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0027] How this utility works:

[0028] Refer to the instruction manual Figure 1-5 For this type of three-phase asynchronous motor with a fault monitoring structure, when in use, the moisture sensor 402 is first installed at the front lower side of the base 401 to monitor the humidity in the motor operating environment in real time.
