Radial magnetizing vacuum cleaning motor

Abstract

The invention provides a radial magnetizing vacuum cleaning motor, and belongs to the technical field of vacuum cleaning motor. A first motor rotor yoke and a second motor rotor yoke form a set, the outer side of the first motor rotor yoke and the outer side of the second motor rotor yoke are each provided with a rotor body retainer ring, and a rotor spacer ring is arranged between adjacent two rotor body retainer rings of the two sets of the motor rotor yokes. A rotor shaft snap spring is arranged on the rear portion of a rotor shaft of the motor, motor rotor yoke positioning pins are arranged on the third motor rotor yoke, the fourth motor rotor yoke, the first motor rotor yoke and the second motor rotor yoke, and rotor permanent magnet embedding ports are formed in the third motor rotor yoke, the fourth motor rotor yoke, the first motor rotor yoke and the second motor rotor yoke. Rotor permanent magnets are embedded in the rotor permanent magnet embedding ports. A bearing spring pad is arranged between a ceramic deep groove ball bearing at the rear end of the motor rotor shaft and a rear end cap of the motor, stator punching sheets are arranged between the motor rotor yokes and a motor casing, and stator punching sheet rivets are arranged on the stator punching sheets. The radial magnetizing vacuum cleaning motor is especially applicable to the aerospace field.

Description

technical field [0001] The invention relates to a vacuum clean motor with radial magnetization, and belongs to the technical field of vacuum clean motors. Background technique [0002] Vacuum clean motors refer to motors that can work under vacuum conditions and meet high cleanliness requirements. [0003] Vacuum clean motors mainly meet the requirements of two aspects, namely vacuum and cleanliness. Vacuum mainly refers to the use environment of the motor to meet a certain degree of vacuum, in which the motor can work normally, and the motor itself will not affect the vacuum environment. The cleanliness here means that in a vacuum environment, certain cleanliness requirements must be met, including not only dust, but also organic molecules. The motor will not affect the cleanliness of the environment during normal use, and can also meet normal work requirements. [0004] Therefore, the requirements for the use of vacuum clean motors are that they can work stably in ultra...

AI Technical Summary

Problems solved by technology

As far as the current domestic and foreign markets are concerned, the German Phytron vacuum motor is widely used and the technology is relatively mature, but the cost is quite expensive, and the vacuum motor produced in China has not really reached the standard of vacuum products. The relevant research results are in the structure optimization , low temperature rise, high stability and cleanliness compared with foreign countries still have a certain gap, especially the design and use characteristics of motors in strong radiation, high vacuum and ultra-clean working environments are rarely studied

And the existing vacuum motors rarely follow the requirements of high cleanliness, and the occasions with cleanliness requirements are generally not used in vacuum environments, and high cleanliness and high vacuum are often not considered at the same time
