(1) technical field
The utility model relates to permagnetic synchronous motor, is specially a kind of duplex permanent magnetic synchronous electric machine.
(2) background technology
Because energy scarcity, oil price is constantly soaring, pure fuel engines drive oil consumption big, pollute and become focus greatly, reason and its engine inconvenience are adjusted working point, efficient and are hanged down relevantly, each state has all accelerated the research of electric motor car.
Years of researches find that there are a lot of problems in pure electric vehicle, mainly are the requirements that present accumulator property can not satisfy powered vehicle.The energy product of storage battery is compared than with gasoline and is differed greatly, and weight is that one ton the energy that storage battery had that is full of electricity is big no more than the energy of 30 kilograms of gasoline outputs of engine combustion, so the flying power of pure electric vehicle is all very limited.Be that the charging interval is long in addition, conversion efficiency is low, and 100 joules electric flux charges into storage battery, and the electric flux that storage battery can be released is less than 40 joules.Though the quick charge time spent is short, battery efficiency reduces more.Particularly the number of times that charges repeatedly of storage battery is limited, and service time is long more, and its capacity is low more, has generally scrapped soon, and a large amount of old and useless batterys will cause environmental pollution again.
Studies show that at present oil and electricity hybrid vehicle is the feasible energy-conservation car of comparison reality, therefore the emphasis of research is transferred to oil and electricity hybrid vehicle.This car has been equipped with fuel engines and storage battery, also has generator and motor simultaneously.Design principle is the working point that participates in regulating engine by engine, electric generator/electric motor, storage battery, the rotating speed and the moment of torsion of engine are mated on its optimum efficiency curve, obtain bigger kinetic energy with realization consumption equivalent fuel oil thereby make fuel engines intermittence or continue efficient operation.Usual way is the needs according to traveling state of vehicle, the mechanical kinetic energy part of the generation of fuel engines is exported to driving shaft, made it to obtain certain torque and rotating speed, remaining kinetic energy then is used to drive generator for electricity generation and is stored in storage battery, when specific location or accumulator electric-quantity were saturated, storage battery drove the motor driven vehicle '.Also can make the fuel engines intermittent duty in the high efficiency state, its kinetic energy transfers electric energy to by generator and is directly passed to motor or is stored in storage battery, the motor driven automobilism.Like this, the operational efficiency of fuel engines increases.
The dynamic structure scheme of existing oil and electricity hybrid vehicle has tandem, parallel and series and parallel combined.Though realized in various degree energy-conservation, all there is certain limitation in the available dynamic structure, directly influence car load manufacturing cost and energy-saving effect.The dynamic structure of present oil and electricity hybrid vehicle is difficult to satisfy the requirement that further improves performance and practicality.
The characteristics of permanent magnet synchronous servo motor are that efficient height, volume are little, the efficient of motor under 100% load factor about 20KW can reach 93%, efficient under 20% load factor reaches 81%, and can switch to generating or electronic different operating state by four-quadrant drive control, if it is made up, transforms, with the engine fit applications in oil and electricity hybrid vehicle, might reach and both be convenient to adjust engine working point, improve transmission efficiency, be convenient to simplified structure again and reduce weight, realize further purpose of energy saving.
