Yes.
According to information from Sohu.com, the motor was running with phase loss. This is a killer of the three-phase asynchronous motor. When the motor is running normally, the three-phase load is a symmetrical load, so the three-phase current is basically balanced and equal in size. If the motor loses a phase during operation, the vibration of the three-blade Roots blower will become larger and appear. Abnormal sound, reduced speed, and increased current will cause the motor temperature to rise sharply, causing the motor to burn out. A motor of average quality will burn out in at most ten minutes.
A wind blade is a device that can convert wind energy into mechanical energy. It usually consists of a series of blades. Its function is to convert the kinetic energy of the wind into rotational kinetic energy. Wind blades are widely used in wind power generation, air conditioning, ventilation and other fields. In wind power generation, blades are one of the core components.
Many people will hear a loud rattling sound from the air conditioner (mainly from the indoor unit) when using the air conditioner, especially when sleeping. There are many reasons for the loud sound of air conditioners. If you want to reduce the sound to a lower level, you need to analyze the specific situation. The following are specific instructions: 1. It may be that the air conditioner has turned on a larger blowing gear. The larger the gear, the louder the blowing noise. Therefore, the air conditioning blowing speed can be appropriately lowered. 2. It may be that the outer casing of the air conditioner indoor unit is not completely closed, causing the vibration generated by the fan during operation to form a greater resonance with the casing, thus producing noise. You can open the outer shell and reset it (check whether there are any protrusions and loose spots around the opening). 3. The noise may be caused by friction between the swing blade parts of the air conditioner and the fixed position. You can add lubricating oil to the fixed position of the swing blade to make it swing more smoothly (if there is dust on the swing blade, you can spray it with air conditioner cleaner to remove it).
