Description
Technical field
The present invention relates to that a kind of " [" shape modular stator-sectional rotor switched reluctance motor belongs to the switched reluctance machines field of electric machinery.

The winding of switched reluctance machines is extremely gone up around stator core tooth, because winding space is less relatively, winding operation is difficult for automation, and the coiling quality is difficult for guaranteeing, thereby has limited motor properties.And the wind resistance when the salient-pole structure rotor makes high-speed cruising is big, oil cooling but under the condition resistance during high-speed cruising bigger.In order to reduce wind (oil) resistance, can increase rotor slot wedge or packing in rotor, though it is obvious to reduce the effect of wind (oil) resistance,, also increased the complexity of rotor structure to the requirement height of technology.
Three-phase 6/4 structure of present research in the world, the on-off reluctance motor with sectional rotor of three-phase 12/8 structure, rotor is a cylindrical structural, wind (oil) resistance in the time of can obviously reducing the rotor high-speed operation, but each winding of stator that full groove distributes must be crossed over a plurality of stator tooths, each winding overlaps at stator end, and the end of the whole winding of motor is very big, has reduced the utilance of winding and has increased the end benefit of motor, also reduce simultaneously the reliability of motor, made the overall performance of motor reduce.Barrie professor C.Mecrow of University of Newcastle has proposed a kind of monodentate winding sectional rotor switched reluctance motor (SRM) of three-phase 12/10 structure, its characteristics are that stator adopts big or small toothing, each winding of stator no longer adopts full groove distributed winding but directly on each stator canine tooth, make each winding no longer cross over a plurality of stator tooths, the end winding does not have overlapping, winding overhang is little, improved the utilance of winding, but the rotor number of poles that they are many relatively, not only make rotor strength reduce, and revolution step pitch number increases, and the power inverter switching frequency increases, thereby increased the cost of motor and controller.
Summary of the invention
It is big to the present invention seeks to propose a kind of winding winding space, is easy to the automation coiling, and wind during high-speed cruising (oil) resistance is little, the novel switched reluctance motor of low cost of manufacture.
The present invention adopts following technical scheme for achieving the above object:
" [" shape modular stator-sectional rotor switched reluctance motor of the present invention, the rotor core piece and the non-magnetic rotor cover that comprise modular stator core piece, stator winding, segmentation, it is characterized in that: modular stator core piece is " [" shape, stator winding is wrapped on the yoke of modular stator core piece, the rotor core piece of segmentation is embedded in the non-magnetic rotor cover, forms the cylindrical structural rotor.
Of the present invention " major advantage of [" shape modular stator-sectional rotor switched reluctance motor:
(1), stator winding is wrapped on the yoke of modular stator core piece, the winding winding space is big, more number of turns can improve the magnetomotive force of motor.
(2), each modular stator core piece winding separately, winding operation is easy to automation, and can guarantee the consistency of each winding of motor, thereby ensures motor properties.
(3), modular rotor core piece is embedded in the non-magnetic rotor cover, forms the cylindrical structural rotor, wind (oil) resistance during the rotor high-speed operation is little.
(4), saved the yoke part of regular tap reluctance motor radial stator, so of the present invention " [" shape modular stator-sectional rotor switched reluctance motor core material consumption is few, and stator core piece modularization, whole motor low cost of manufacture.
