Abstract

The invention provides a compact low-noise three-phase induction motor which comprises a motor base. A stator is sleeved in the motor base in a heating mode. Front and rear end covers are installed atthe two ends of the motor base respectively, and a rotating shaft is installed in the motor base and supported and fixed through front and rear bearings. A rotor and an inner fan are sleeved on therotating shaft, andan outer fan is arranged at the tail end of the rotating shaft. A fan cover is installed at the rear end of the motor base. The compact low-noise three-phase induction motor is characterized in that the motor base is provided with novel heat dissipation ribs; the front end cover is provided with a novel guide plate; and rotor short-circuit ring blades and the inner fan form a novel inner fan device. Heat dissipation ribs are arranged on the surface of the fan cover, and a special air guide cylinder is installed in the 2P motor. The motor is compact in structure, low in noise, attractive in appearance, small in vibration and low in cost.

Description

technical field [0001] The invention relates to the technical field of induction motors, in particular to a compact low-noise three-phase induction motor. Background technique [0002] Three-phase induction motors are simple in structure and easy to maintain, and are widely used in compressors, water pumps, steel, crushers, papermaking and other industries. The existing electric motor has a large volume and high noise. The size is not conducive to the installation of the motor in confined spaces. High noise seriously affects people's work, life and health. [0003] At present, the market demand for compact low-noise motors is increasing, the market potential is huge, and the economic benefits are also considerable. [0004] Based on the above reasons, it is necessary to improve the current induction motors with high noise and large volume. Contents of the invention [0005] The object of the present invention is to provide a compact low-noise three-phase induction moto...
