Description
Technical field
The utility model relates to a kind of traction electric machine, especially relates to a kind of hybrid power car permanent-magnet synchronous traction electric machine that is suitable for.
Background technology
The most outstanding advantage of permanent-magnet synchronous traction electric machine is that specific power is big, and electric automobile requirement traction electric machine size is little and power is big, and the permanent-magnet synchronous traction electric machine just in time adapts to this requirement.But existing permanent-magnet synchronous traction electric machine adopts the natural wind cooling, because interior space is narrow and small, ventilated environment is poor, flowing gas produces the vortex flow loss in the car, thereby cooling effect is not good enough, and motor temperature raises easily, and temperature rise is too high, can cause the permanent magnet demagnetization to lose efficacy the motor premature damage.
The utility model content
The purpose of this utility model is to overcome the existing existing above-mentioned defective of permanent-magnet synchronous traction electric machine, provides in a kind of running temperature rise little, the water-cooling permanent magnet sync pulling motor of long service life.
The purpose of this utility model is achieved by the following technical solution: it includes support, stator, rotor, rotor field spider, electrical equipment coupling, welding point, shielding webmaster, resolver, it is characterized in that, be fixedly connected with welded cover plate on the support, the inner ring of described welded cover plate and stator cylindrical interference fit, have water-cooling channel on the welded cover plate, and be provided with water inlet and delivery port, water inlet and water tank link, delivery port and water pump link, also be provided with the seal suitable, form the water-cooled circulation canal with water-cooling channel.
Preferred version: the magnetic pole in the rotor is made up of at least two blocks of magnet steel.
The utility model compact conformation, power density is big, adopts water-cooling structure, and cooling water flow can be taken away a large amount of heats, and good cooling results can effectively reduce electric machine temperature rise, prevents that the permanent magnet magnet steel lost efficacy because of the too high demagnetization of temperature rise; Magnet steel is cut into less magnetic patch, be assembled into a magnetic pole again, also can reduce demagnetization, prolong the useful life of magnetic pole.
The utility model is particularly suitable for the traction electric machine as the parallel type hybrid dynamic car.
