Description
Technical field
This utility model is particularly to a kind of multiple stators heterogeneous direct-drive permanent-magnetism electromotor.
Background technology
The most conventional wind-driven generator is single stator permanent magnet direct wind-driven generator, and it there is problems of, according to electricity
The basic relational expression of machine key dimension, rated power and rotating speed, due to the slow-running characteristics of wind-driven generator, (rotating speed is tens
Turn even tens turns), cause generating set to need to take the special construction of multipole, multipole winding needs the stator circle at electromotor
Launch on week so that issuing motor diameter at equivalent capability relatively big, now the power density of motor is less, motor space availability ratio
The highest, thus limit motor output voltage.Therefore, large-scale direct-driving permanent-magnetic wind-driven is needed to study new motor
Structure sufficiently utilizes motor space, it is thus achieved that higher power density, it is thus achieved that higher output voltage, relatively low output electricity
Stream, improves generator operation efficiency.
In three-phase system, for improving generator capacity, people typically increase the voltage of electromotor or electric current carries
High power, but the increase of voltage or electric current improves the requirement of power electronic devices in inverter.Due to power electronics energy
The voltage or the electric current that bear are limited, therefore need the mode using series connection dividing potential drop to share each power electronics device under high-pressure situations
The voltage that part is born, then needs to carry out the electricity that parallel connection makes the power electronic devices in every branch road flow through under big current conditions
Flow in allowing tolerance range.Such control mode had both added the requirement to power electronic devices, improve again control system
System complexity, reduce system by reliability, need develop New-type electric machine to meet people's demand to energy.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of multiple stators heterogeneous direct-drive permanent-magnetism electromotor, and this is the most fixed
The heterogeneous direct-drive permanent-magnetism electric generator structure of son is simply unique, and reliability is high.
The technical solution of utility model is as follows:
A kind of multiple stators heterogeneous direct-drive permanent-magnetism electromotor, including M stator and M-1 rotor, M >=3；Each stator has
There is N phase winding；N≥3；M and N is integer；
Stator and rotor alternate intervals are arranged, and are followed successively by from inside to outside: the first stator, the first rotor, the second stator, second
Rotor ..., M-1 stator, M-1 rotor and M stator.
Stator winding it is provided with, corresponding phase winding series connection in each stator in stator.
Described N is 6,8 or 12.
Preferably, N=6, M=5；The position relationship of 5 stators and 4 rotors is:
Be followed successively by from inside to outside the first stator, the first rotor, the second stator, the second rotor, the 3rd stator, third trochanter,
4th stator, fourth trochanter and the 5th stator.
Winding uses polyphase windings, and the number of phases of motor is specifically chosen according to Principle of Electric Engine.Conventional has 6 phases, 8 phases, 12 phases
Winding etc..
Beneficial effect:
Multiple stators of the present utility model heterogeneous direct-drive permanent-magnetism electromotor, the every corresponding series connection of winding of multiple stators structure is even
Connecing, i.e. from the beginning of the 1st stator, the stator correspondence phase armature winding of each stator every phase armature winding and other correspondences is successively
Head and the tail are connected in series with each other, and constitute the series connection of multiple stator winding correspondence phase winding successively, and every phase winding draws two end points.
Thus can obtain more higher output voltage than conventional electric generators.Finally, the wind that frequency is changed by a total power converter is used
Electricity is transformed to power frequency electric and sends into electrical network.Owing to using heterogeneous structure so that the device parameters grade of current transformer reduces, current transformer
Control to become simple.Therefore, this multiple stators heterogeneous direct-drive permanent-magnetism electric generator structure is simple, it is easy to implement, it is easy to control, to control
Circuit processed (current transformer etc.) requires low, thus reliability is high.
