Description

Technical Field

[0001] The utility model belongs to the technical field of motor equipment, in particular to an AC motor with noise reduction and dust prevention. Background Art

[0002] AC motor is a machine used to realize the mutual conversion between mechanical energy and AC electrical energy. Due to the tremendous development of AC power systems, AC motor has become the most commonly used motor. Compared with DC motor, AC motor has no commutator, so it has a simple structure, is easy to manufacture, is relatively strong, and can be easily made into a high-speed, high-voltage, high-current, and large-capacity motor. The power coverage of AC motor is very large, from a few watts to hundreds of thousands of kilowatts, or even millions of kilowatts.

[0003] Existing noise-reducing and dust-proof AC motors generate a lot of heat when working. In the related art, the motors are generally equipped with fans to increase the air flow, thereby dissipating the heat of the AC motor. However, as the air flows, dust in the outside air will enter the motor with the airflow, which will cause great damage to the motor. The motor will also generate a lot of noise during operation. If the noise of the motor is further reduced, part of the heat dissipation must be sacrificed. It is difficult to take both into account. Therefore, a noise-reducing and dust-proof AC motor is proposed. Utility Model Content
