Background technique
Permanent magnet synchronous motor is the synchronous motor that synchronous rotary magnetic field is generated by permanent magnet excitation, and permanent magnet is produced as rotor
Raw rotating excitation field, threephase stator winding, by armature-reaction, incude three-phase symmetrical electric current under rotating excitation field effect.
Rotor kinetic energy is converted into electric energy at this time, and permanent magnet synchronous motor is used as generator (generator)；In addition, working as stator
Side is passed through three-phase symmetrical electric current, since threephase stator differs 120 on spatial position, so threephase stator electric current produces in space
Rotating excitation field is given birth to, is moved in rotor rotating excitation field by electromagnetic force, electric energy is converted into kinetic energy at this time, and permanent magnet synchronous motor is made
Motor is used.
Sealing can be divided into static seal and dynamic sealing two major classes.Static seal mainly has pad sealing, sealant sealing and directly connects
Touching sealing three categories.According to operating pressure, static seal can be divided into mesolow static seal and high pressure static seal again.Mesolow static seal
The pad of the softer wider width of common material seals, the metal gasket that high pressure static seal then uses the harder contact width of material very narrow.It is dynamic
Sealing can be divided into two kinds of fundamental types of rotatory sealing and reciprocation sealing.Other components performed relative motion by sealing element with it
Whether contact, contact seal and non-contacting seal can be divided into；Can be divided into again by sealing element and contact position circumferential sealing and
End face seal, end face seal are also known as mechanical seal.Centrifugal seal and helixseal in dynamic sealing, when being by machine run
It is sealed to medium with power, therefore sometimes referred to as dynamic seal.
Traditional permanent magnet synchronous motor sealing structure is still leaky, and waterproof effect is bad, if being used for wet environment, on motor
Lid one end easily intakes, into silt, and service life greatly reduces, it would therefore be highly desirable to which a kind of improved technology solves the prior art
In the presence of this problem.
