A Magnetic Suspension Bearing Disc Type Precision Air Conditioning Fan

Abstract

The invention discloses a magnetic bearing disc type precise air-conditioner fan, comprising fan blades, a motor and at least one magnetic bearing, wherein the motor comprises a motor stator, a motor rotor and a stator shaft fixedly arranged on the motor stator; the magnetic bearing comprises a magnetic bearing rotor arranged on the stator shaft and a magnetic bearing stator with an E-shaped section and arranged in a fan blade sleeve; and six stator teeth are axially arranged on the motor stator, a winding is wound on the stator teeth, and the motor rotor comprises four salient pole mechanism arranged on the fan blade sleeve. The magnetic bearing disc type precise air-conditioner fan has the beneficial effects that no mechanical friction is generated between the stator and the rotor, the mechanical noise and vibration are eliminated, the noise and vibration of the air-conditioner fan are greatly reduced, no cooling system and lubricating system are needed, meanwhile the size and weight of the fan are also reduced, and the effects of energy conservation and emission reduction are realized.

Description

technical field [0001] The invention relates to a fan, in particular to a disc-type precision air-conditioning fan with a magnetic suspension bearing. Background technique [0002] The fan blade motors of precision air conditioners include AC motors and DC motors, and the fan blade motors are the power source for driving the fan blades. According to the working nature of the precision air conditioner, the fan motor should have the following characteristics: [0003] 1. Long-term continuous operation with high load: Most special occasions require precision air conditioners to operate 24 hours a day, 365 days a year. Therefore, the dedicated motors for precision air conditioner fans should work in a high-load long-term continuous operation system. [0004] 2. Large flow rate: According to different application occasions, the air supply mode of precision air conditioners generally adopts upward air supply or downward air supply. In order for the air conditioner to radiate the...
