The structure of the traction electric machine of hybrid power motor train unit as shown in Figure 1, the structure of the motor rotor punching sheet in traction electric machine as shown in Figure 2, the permanent-magnet structure of the V-arrangement radial magnetic circuit structure that motor rotor punching sheet adopts magnet steel groove narrower, because magnet steel groove is narrower, motor anti-degaussing ability is low, output voltage changes greatly with power of motor density little; The structure of rotor permanent magnet baffle plate trim ring as shown in Figure 3, rotor permanent magnet baffle plate trim ring adopts the circular configuration of steel plate machine-shaping, this structure only can play and compress permanent magnet baffle effect, because rotor exists magnetic and steel plate structure trim ring assembles difficulty during installation, and overall weight is larger; The structure of support as shown in Figure 4, motor is water-cooling structure, support adopts barrel soldering or single-screw copper pipe cast structure, and the general volume of welding frame is comparatively large, limited for railcar motor mounting space, mostly adopt cast structure at present, single-screw copper pipe cast structure is arranged in support wall by a copper pipe, this structural electromotor water resistance is comparatively large, and water speed is lower, inapplicable when this explicitly calls for electric machine temperature rise, water resistance etc.
Summary of the invention
The present invention, in order to solve existing totally-enclosed machine weak heat-dissipating, volume is large and weight is large problem, provides hybrid power motor train unit permanent magnet generator.
The present invention adopts following technical scheme to realize: hybrid power motor train unit permanent magnet generator, comprise support and end cap, the stator assembling containing stator coil and the assembling of the rotor containing rotating shaft, rotor core, permanent magnet baffle plate, permanent magnet baffle plate trim ring and permanent magnet is provided with in support, rotating shaft two ends are also provided with front internal sealed ring and rear internal sealed ring, support is cast aluminium support and adopts double spiral copper pipe cast structure in parallel, permanent magnet baffle plate trim ring is cast aluminum construction, and trim ring is evenly arranged alinco assembled removal hole.
Support is cast aluminium support and adopts double spiral copper pipe cast structure in parallel, under same volume, can effectively reduce motor weight, increase electric machine temperature rise nargin, meeting under motor strength conditions, double spiral copper pipe has the advantages such as motor water resistance is low, good heat dissipation simultaneously; Permanent magnet baffle plate trim ring is cast aluminum construction, and trim ring is evenly arranged alinco assembled removal hole, can effectively compress two ends permanent magnet and baffle plate thereof, reduce motor weight simultaneously, facilitate permanent magnet to assemble and dismounting, avoid permanent magnet to damage, thus attenuating motor cost, improve motor reliability.
The invention has the beneficial effects as follows:
1) cast aluminium permanent magnet baffle plate trim ring can reduce own wt, trim ring is evenly arranged alinco assembled removal hole, can ensure that motor assembles, and reduces design cost, improves operational reliability and life-span;
2) motor adopts totally-enclosed water air-cooled structure, and support is that cast aluminium support adopts double spiral copper pipe cast structure in parallel, under same volume, can effectively reduce motor weight, increase electric machine temperature rise nargin, meet motor to water resistance and temperature requirement;
3) research and development of this motor and operation, for mixing motor train unit industry research and development magneto alternator provides realistic basis.
