Description
Technical field
The present invention relates to technical field of motor manufacture, and in particular to a kind of adjustable speed motor.
Background technique
Motor has been used widely in the production of the mankind and life at present, small to arrive electronic toy, train is arrived greatly, from work
Factory to rural area, from public institution to business unit etc..
What is developed first in the development of motor is direct current generator, because what is obtained and promote at first is direct current.Direct current
The development of motor can substantially be divided into four-stage.(1) it is stage using permanent magnet as magnetic field, this is initial direct current drive
The common feature of machine.(2) using electromagnet as the stage of magnetic pole.(3) phase III is the stage for changing excitation mode.(4) straight
The fourth stage of galvanic electricity machine development is exactly to advance on practical road towards the direction of improvement, is mainly reflected in armature rotor
Improvement on.Dentation armature is invented within 1865；Cyclic annular armature is invented within 1870；Invent a kind of drum type rotor within 1872,
The cost of motor production technology is reduced, the epoch that motor obtains practical application come finally.But with DC generation skill
The limitation of art especially HVDC Transmission Technology, alternating current generator start to receive the attention of engineers again.Italy in 1885
Physicist, electrician scholar add sharp leo Roberto Ferraris, American physicist Ni Gula tesla in 1886 independent
Rotating excitation field is invented, several coils are lined up a circle with radial by them, are accessed alternating current, are made the alternating current in each coil
Frequency is identical, but its voltage, electric current have a phase shift, and the space in this way between coil forms a rotating excitation field, and this
Magnetic field will drive hot-wire coil rotation, they succeed in developing two-phase alternating current motor in this way.Russia engineer Du Liefu-Du in 1889
Wave Lip river Wals base has invented squirrel-cage three-phase motor, this is the three phase alternating current motor that First can be practical, and so far motor is sent out
The stage that can enter industrial application is opened up, the type motor is industrially applied because not being adjustable its speed, and cannot be obtained
It is promoted to extensive, therefore occurs adjustable speed auxiliary equipment on the basis of motor, developed novel adjustable speed motor.
Adjustable speed motor currently on the market have electromagnetism it is adjustable with adjustable two kinds of frequency conversion, the speed regulation of two kinds of motors needs are matched
The parameter of motor is closed, such as motor, power, revolving speed, voltage, electric current combine, both modes of speed regulation can only be in original motor
Revolving speed on the basis of adjust the speed downwards, be unidirectional speed regulating motor, it is related to reduce motor power downwards, be allowed to be short of power, adjust
Fast inconvenient, use is also inconvenient.
