Abstract

The invention relates to a reversible motor generator capable of realizing self starting. The reversible motor generator can be used as an electric motor and a generator, thereby having dual functions. The reversible motor generator has the advantages of light-weight structure, large power density, obvious energy-saving effect, high efficiency, low failure rate, low operating maintenance cost, high load-carrying capacity and high impulse force resistance to sudden loading and unloading. The invention solves the technical problems that toroidal damped starting windings can not be mounted onto the traditional product due to the structural restriction and permanent-magnet steel is breakable in the operating process, and makes up the technical defects of high rotor structure flux leakage, poor voltage regulation factor, low air-gap induction, low power density and the like of the traditional product. The reversible motor generator can replace the traditional synchronous motor, induction type asynchronous motor and synchronous generator and asynchronous generator. The reversible motor generator is especially suitable for being mounted on an automobile chassis, and can be driven by an automobile engine to generate electricity, thereby having broad application prospects.

Description

The reversible motor generator

Technical field:

Reversible motor generator of the present invention belongs to the energy-saving electric machine field.

Technical background:

Existing motor adopts electric energy to be converted to mechanical energy and produces power, and after applying power conversely and giving motor, motor can not generate electricity.Equally, existing generator adopts mechanical energy to be converted to that electric energy generates electricity, and after applying electric energy conversely and giving generator, generator can not produce power.Have only single function, do not possess invertibity.

Summary of the invention:

The object of the present invention is to provide the self-running reversible motor generator of a kind of energy, not only can do motor with but also can do generator usefulness, a machine is difunctional.Structure is light and handy, power density is big, energy-conservation obviously the efficient height, fault is few, operation expense is low, and it is strong to drive load capacity impact resistance strong and the sudden unloading process load.

The technical solution used in the present invention:

The present invention compared with prior art, its advantage is:

1, adopt permanent-magnet steel to make the rectangle permanent-magnet steel, comparable existing employing tile shape permanent-magnet steel constructed products has higher power density and lower cost.

2, to adopt the segmental rotor punching of n group five equilibrium to be stacked on n the key bar of rotor axle sleeve assembly unit synthetic in rotor core, and rotor axle sleeve is fixed in the rotating shaft, constitutes the individual equally distributed damping hole of n equally distributed polygon location notch and n.

3, the rectangle permanent-magnet steel is installed in the polygon location notch in the rotor core, be arranged in n in order to the N utmost point and S utmost point field structure, improve the air gap flux density and the power density of complete machine greatly, remedied the low and low technological deficiency of power density of existing product air gap flux density.

4, damp type is started sliver and pack in the damping hole, damp type starting lead ring is installed on the two ends of damp type starting sliver, constitute ring-like damp type starting winding.But make motor with self-starting, make generator, remedied existing product and be subjected to the restriction on the self structure that technological deficiencies such as ring-like damp type starting winding can not be installed with improving impact resistance and running stability.

5, adopt rotor end ring fixed rotor iron core and rotor axle sleeve, improved the installation effectiveness and the mechanical strength of rotor assembly greatly.

6, adopt the full-closed water-proof structure, be installed on the automobile chassis, drive generating with car engine, it is light and handy to have structure, characteristics such as generating efficiency height.
