Description
Technical field
The present invention relates to a kind of semi-open formula permanent magnet motors, belong to motor technology field.
Background technique
Rail traffic generallys use air-cooled, liquid cooling the type of cooling with traction motor, including closed forced air cooling, opens
Formula is opened from fanning wind cooling, casing liquid cooling etc..Wherein, closed forced air cooling is the cooling wind of motor interior by outside motor one
The individual blower supply of platform, meanwhile, the revolving speed of blower is not influenced by motor speed, i.e., motor is run under any state
Air quantity is constant.Open-type is that fan is mounted on motor reel from the characteristics of fanning wind cooling, and fan is coaxial with motor rotor, revolving speed
Identical, the power of fan consumption is provided by the mechanical output of shaft.The structure of liquid cooling is base using double-walled construction, and coolant liquid is circuitous
The modes such as dynamic that flow back flow through base, to cool down stator core.
In the prior art, since permanent magnet synchronous traction motor is not necessarily to rotor field electrical excitation, excitation mode is encouraged for permanent magnetism
Magnetic, simultaneously as the particularity of permanent magnet, motor need to prevent the foreign matters such as dust, moisture, soda acid from entering motor interior, break
Bad permanent magnet, it is electronic especially for preventing the metal powder that wheel and rail friction generate when the operation of rail locomotive vehicle from entering
Inside machine and it is adsorbed on permanent-magnet motor rotor surface, so that motor stator, rotor airgap be caused to become smaller, or even sweeps thorax, therefore,
Permanent magnet synchronous traction motor generallys use full-closed structure.And according to permanent magnet synchronous traction motor running environment condition, with
And permanent magnet synchronous traction motor rotor has the characteristics that magnetic easy absorption iron impurities, permanent magnet synchronous traction motor is usual
Using the totally enclosed air-cooled type of cooling.As shown in Figure 1, totally enclosed air-cooled cooling scheme be cooling medium in outer fan or
Under the action of included fan, motor heat is taken away by motor outer circulating air duct, that is, passes through the ventilation hole in stator module 1
11 (as shown in Figure 2) take away the heat of motor interior.Wherein, arrow show cooling wind fluid flow direction in Fig. 1.But
It is that the main problem of totally enclosed air-cooled cooling scheme is that the heat of motor interior especially winding overhang can only be by electronic
Air transmitted inside machine is to outer circulating air duct wall, not only conducting pathway path length, but also inner air flowing property is poor, for high torque (HT)
For the motor of density, the heat-sinking capability of the totally enclosed air-cooled type of cooling is limited, and motor temperature is higher, especially will cause
The temperature of stator winding 12 (as shown in Figure 1) end is excessively high.If permanent magnet synchronous traction motor uses liquid cooling mode, still
Problem is applied there are a series of, liquid cooling mode is not only high to the sealing requirements of cooling system, needs to solve coolant liquid to metal
Corrosion and operating temperature be cooled liquid solidify, the limitation of vapourizing temperature, and it is also required to provide liquid cooling system.However, due to
In field of track traffic major part vehicle, the liquid cooling system for cooling down motor, therefore the liquid cooling system meeting are not set specially but
The cost for increasing trailer system, causes less economical.If permanent magnet synchronous traction motor is cold using traditional open-type ventilation
But structure, then equally exist it is a series of using problem, due to the absorption of rotor permanent magnet, iron powder and iron filings in cooling air etc.
It is readily adsorbed in rotor surface, so that air gap blocking, rotor be caused to sweep the failures such as thorax, is brought to the normal operation of motor hidden
Suffer from.
