Abstract

The invention relates to an efficient motor generator I. When the efficient motor generator is used as a motor, self-starting is achieved, torque is large, a power factor is high, and the range of stable operation is wide. When the efficient motor generator is used as a generator, output power is high, a voltage regulation factor is good, a voltage waveform deviation factor is small, a dynamic property is good, and dual functions are achieved. The efficient motor generator is small in resisting moment, light in weight, high in power density, high in efficiency, obvious in energy conservation, few in breakdown, long in service life, and low in manufacturing cost and operation maintenance cost, and is widely used for drive motors of new energy automobiles or used for replacing existing motors or generating equipment with high energy consumption.

Description

The efficient electric generator

Technical field

Efficient electric generator I of the present invention belongs to the environmental protection and energy saving machine field.

Background technology

Existing motor adopts electric energy to be converted to mechanical energy and produces power, apply conversely power to motor after, motor can not generate electricity.Equally, existing generator adopts mechanical energy to be converted to that electric energy generates electricity, apply conversely electric energy to generator after, generator can not produce power, only has simple function, does not possess invertibity.Moreover efficiency is low, energy consumption is large, fault is many, manufacturing cost and operation expense high.

Summary of the invention

The present invention relates to a kind of efficient electric generator I, but do self-starting for motor, moment of torsion is large, power factor is high, the smooth operation wide ranges.Make generator large by power output, voltage regulation is good, voltage-form distortion rate is little, dynamic property is good, a machine is difunctional.The moment of resistance is little, body weight is light and handy, power density is large, efficiency is high, energy-conservation obviously, few, the long service life of fault, manufacturing cost and operation expense low, be widely used in the new-energy automobile drive motors or substitute existing large motor and the generating equipment of energy consumption.

Compared with prior art, its advantage is technical solution of the present invention:

1, permanent magnetic material is done orthogonal permanent magnet [5] shape, and the permanent magnet magnet steel cost of comparable existing employing tile shape is low and power density is high.

2, efficient electric generator I is external stator [1], internal rotor [2] permanent magnet excitation structure, has wire casing [14] on external stator [1], the inner winding [15] that is embedded with of wire casing [14].Have axis hole [6] and location notch [7] on rotor core [3], rotor core [3] and bearing [10] are enclosed within rotating shaft [8].

3, rotor core [4] embeds above n equally distributed rectangular aperture groove [9] of formation of rotor core [3] key bar [7], and rectangle permanent magnet [5] embeds and cements in formation n in n equally distributed rectangular aperture groove [9] N-S utmost point internal rotor [2] is not waited to the air gap field structure.This structure can improve air gap flux density and power density, and efficiency is high, the moment of resistance is little, can make up the low little technological deficiency of power density that reaches of existing product air gap flux density.

4, on rotor core [4], short-circuited conducting sleeve [11] is housed, short-circuited conducting sleeve [11] is made by bus weldering riveting, but self-starting.Dynamic property is good, voltage-form distortion rate is little, the smooth operation wide ranges, can make up the technological deficiency of existing product bad dynamic performance.

5, in internal rotor [2] is packed external stator [1] inner circle into, end cap [13] is fixed on casing [12] seam, the center of internal rotor [2] in external stator [1] inner circle, location.
