Description
Technical field
The present invention relates to the variable speed constant frequency constant voltage brushless three-phase generator of power taking in a kind of the advancing.
Background technology
As everyone knows, when synchronous generator changed when the hauling machine rotating speed, the generating frequency of generator also changed synchronously.The field boundary that changes at prime mover rotating speed closes, and for constant frequency generation, generally is to regulate the control rotating speed by special mechanical device, and making rotating speed is a steady state value.
Patent No. ZL02279031.4 integral type variable speed constant frequency constant voltage brushless generator group is exactly by a kind of electromagnetic coupler the pace of change of prime mover to be become constant speed output.Constant thus rotating speed drives synchronous generator, reaches constant frequency generation.
But this structure is owing to must increase electromagnetic coupler or Vulcan coupling, increased an intermediate link, this intermediate link will transmitted the energy greater than the generator rated capacity, this middle device volume is big, this vscf generator group volume is increased greatly, in the limited space of automobile, be difficult to large-scale popularization.Another way is behind the variable speed generation inversion after the AC rectification to be exported the alternating current of constant frequency, this inverter capacity is compatible with generator capacity, cost is also more expensive than generator itself, and the application field boundary that the electric energy quality of inversion simultaneously can't adapt to some special requirement closes.
Summary of the invention
The variable speed constant frequency constant voltage brushless three-phase generator that the purpose of this invention is to provide power taking in a kind of the advancing, the volume of its motor dwindles greatly, provide the power inverter capacity of constant frequency to reduce greatly, only need the slip power control inverter that capacity is much smaller, like this cost reduce greatly and electrical property also more excellent.
The present invention is achieved like this, generator is by power motor, the control motor, three electronic coaxial-type motors of multipole magneto are formed, it is characterized in that being connected with in the power motor stator of generator two covers, three phase windings, one cover is the three-phase main winding, one cover is a three-phase triple-frequency harmonics winding, one cover, three phase windings are arranged in the control motor stator, one cover, three phase windings are arranged in the multipole permanent magnet motor stator, wherein power motor three-phase main winding is externally exported the constant frequency and constant voltage alternating current, and three-phase triple-frequency harmonics winding, three phase windings of control motor and three phase windings of multipole magneto all link to each other with frequency converter, settle permanent magnet in the rotor of multipole magneto, all settle five phase windings in the rotor of power motor and control motor, this two kind of five phase winding is direct-connected mutually, frequency converter also is connected to the mechanical separator speed signal of power motor output voltage measuring-signal and power taking machinery, frequency converter is according to these signals, regulate the alternating current of the variable-size of output variable frequency and make excitation usefulness, reach generating function variable speed constant frequency supplied with constant voltage alternating current for the stator winding of control motor.
Advantage of the present invention is: (1) volume is significantly smaller than existing integral type variable speed constant frequency constant voltage brushless three-phase generator group; (2) provide the power inverter capacity of constant frequency to reduce greatly; (3) the cost cost reduces and electrical property is more excellent.
