Abstract
The utility model relates to a high-power high-speed permanent magnetmotor or generator. The laminated sheets of stator iron-core are evenly equipped with location fins at the outer edge, a lower trunking at the internal side. The magnetic steel of the rotor is composed of four sectorial magnetic steel along the circumferential direction and four sections along the axial direction. The stator winding is the three-phase and two polar, which appears symmetric distribution along the rotor axis, total 24 turns with 2 turns of each trunking and 12 trunkings for each phase. The N type magnet steel and the S type magnet steel are about 8 pieces respectively. The utility model has the advantages of easy starting, stable operation and working at below 36000rpm due to the low-voltage frequency inverter. The utility model not only operates as the motor but also the generator, if as the motor, it realizes the soft starting and operation of the motor with the power more than 100kW and the speed to 60000rpm, and forms the micro power generator by combined with micro gas turbine or other power machines.
Description
Technical field: the utility model relates to a kind of Large-power High-Speed permanent-magnet electric/generator.
Background technology: the permagnetic synchronous motor range of application is very extensive at present, almost spreads all over the every field of Aero-Space, national defence, industrial and agricultural production and daily life.In epitrochanterian position difference, traditional permanent-magnetic synchronous motor rotor magnetic structure is mainly built-in and Lundell according to permanent magnet.The built-in rotor magnetic structure, permanent magnet is positioned at internal rotor, between permanent magnet and the stator core pole shoe is arranged, and can prevent cast aluminium cage or copper bar cage in the pole shoe, is mainly used in the common Low speed electric motor with asynchronous starting.The claw-pole rotor magnetic structure is made up of ring flange and a round ring magnet of two band pawls usually, and this kind motor performance is lower, does not possess the asynchronous starting ability.Yet the higher power of motor of rotating speed is very little, and the rotating speed that power is bigger is lower again.
Summary of the invention: the purpose of this utility model provides a kind of rotating speed height, high-power high-speed permanent magnetic dynamoelectric machine.Technical solution of the present utility model is that the outer rim of the iron core laminate patch of stator is evenly distributed with the location fin, and is inboard for descending wire casing; Rotor magnetic steel is divided into four sections vertically along circumferentially being made up of 4 blocks of fan-shaped magnet steel.Stator winding is the three-phase two-stage, and every phase winding is symmetrically distributed with armature spindle, every groove 2 circles, and every phase 12 grooves are totally 24 circles.The N polar form magnet steel of rotor and S polar form magnet steel respectively are 8.Effect of the present utility model is that the utility model adopts surface-type radial rotor magnetic structure.In this structure, permanent magnet is tile shape, is positioned at the outer surface of rotor core, and the flow direction that permanent magnet provides is for radially.This kind structure is easy to realize that optimal design makes the motor gas-gap magnetic flux density waveforms trend towards sine wave, can realize high rotating speed, high-power characteristics.Compare 36 groove stators with non-groove stator, few groove stator in addition, air gap is less, although the field frequency of slot ripples is higher, amplitude is less.Because rotor adopts the magnet steel of sector structure, and segmentation is installed on the mandrel, and stator winding is the wye connection of no neutral lead, stator winding employing multiply and around, winding rolls off the production line by the three-phase two-stage, makes the class of insulation reach the F level.The utility model adopts the low voltage frequency converter starting easily, and is stable, can be operated in 36000r/min and following; Both can be as the motor operation, also can be used as generator operation,, reach the soft start and the operation of 60000r/min motor above 100kW, rotating speed to realize power as motor, supporting with miniature gas turbine or other dynamic power machines, can constitute the micro generation unit.
