Description

A high-efficiency spray atomization motor

technical field

The utility model relates to a motor, in particular to a high-efficiency spray atomization motor.

Background technique

High-efficiency atomizing motors have a wide range of applications, including humidification, dust removal, spraying, etc., which can be used in various industries, especially in the spray cooling environment. The first large-scale application was in the Aichi World Expo in Japan, and the most successful application was in the Shanghai World Expo. . There are several defects in the existing centrifugal atomizing motors on the market. Firstly, the motor magnets are exposed. Although there is a certain protection, the atomizing motors generally work outdoors, exposed to the sun and rain for a long time, and the magnets are severely cracked; secondly, the magnets are covered in On the rotor, since the material of the rotor is a plastic product, the coefficient of expansion at the same temperature is quite different, so the gap between the magnetic steel sleeve and the rotor becomes larger and larger after a long time, causing the magnetic steel sleeve to rotate while the rotor does not. If the rotor does not rotate, the atomizing disc does not rotate. The main shaft is the stator, and the atomizing disc is installed on the main shaft. Since the main shaft is made of ceramic material and the ceramic material is brittle and has no toughness, as long as there is a slight error in the concentricity of the rotor, the main shaft will break immediately.
