For electronlmobil, adopt the sinusoidal three plase alternating current of high efficiency high-frequency high-voltage electrical generator output high frequency in the utility model, behind three-phase commutation bridge, directly export high voltage direct current to high efficiency high potential permanent-magnet brushless DC electric machine powered vehicle.Because adopt the high potential scheme, the electric current in the car load driving circuit is less, can guarantee that electronlmobil adopts the stability of heavy-duty motor, has guaranteed the load-carrying ability and the acceleration capacity of electronlmobil.Drive motor adopts permasyn morot or brushless, permanently excited direct current motor, is a kind of performance-oriented electrical motor.Its maximum characteristics are exactly to have the total external characteristics of DC motor and the mechanical contact structure formed of brush.Simultaneously, it adopts permanent magnet rotor, does not have excitation loss, and heat-producing armature loop is contained in again on the stator of outside, and heat radiation is easy, and therefore, electrical motor does not have sparking on commutator, does not have radio interference, and the life-span is long, and is reliable, keeps in repair easy.
This scheme is made up by efficient power generator and high-efficiency electric motor, compares to have higher energy density and the efficient of Geng Gao.
For Electrical Bicycle (comprising battery-operated motor cycle), adopt the sinusoidal three plase alternating current of high efficiency high frequency low voltage electrical generator output high frequency in the utility model, behind three-phase commutation bridge, directly export low-voltage DC to low pressure permanent-magnet brushless DC electric machine powered vehicle (general in the market type voltage is 36V/48V).Owing to adopt the present general-duty permanent-magnet brushless DC electric machine of Electrical Bicycle, it is supporting easy to have guaranteed, use cost is low, safeguards simple.
In actual applications, energy supplement mode of the present utility model can adopt oil and electric dual mode.

Under normal conditions, available civil power (220V) charges a battery, storage battery (36V/48V dynamic lithium battery) but direct drive motor is advanced battery-driven car.Motor speed is changed by dc controller to be adjusted.
Under this pattern, can provide the energy consumption of most economical environmental protection.
2, pure generator for electricity generation drive pattern: turn on the change-over swith on the circuit behind the rectifier bridge, disconnect the change-over swith on the circuit behind the storage battery.
Under storage battery short of electricity situation, can start the high frequency generator generating, through three-phase commutation bridge output DC direct drive motor battery-driven car is advanced.Motor speed is changed by control electrical generator throttle size.
Under this pattern, use dynamical high frequency generator generating, cooperate dynamical permanent-magnet brushless DC electric machine to drive.Electrical generator is directly given the electrical motor powered operation, drives wheel and advances, and does not need mechanical variable speed device fully, compares the pattern of common driving engine by the drop-gear box transmission, and this scenario-frame is simpler, lighter, cost is lower, efficient is higher.
Because the electrical generator throttle under this pattern is variable, motor speed is changed by control electrical generator throttle size, controls aspect the sensation and regular fuel vehicle basically identical at vehicle power, and popularization is preferably arranged.More obvious fuel economy is arranged when low speed driving simultaneously.
3, battery and electrical generator parallel drive pattern: turn on the change-over swith on the circuit behind the rectifier bridge, also connect the change-over swith on the circuit behind the storage battery simultaneously.
Under the situation that the high-power running of needs charges a battery simultaneously, open the high frequency generator generating, through three-phase commutation bridge output DC rear drive motor in parallel with storage battery.Motor speed is changed by dc controller to be adjusted.
Under this pattern, the dc voltage of high frequency generator rectification output is within the specific limits a little more than battery tension, and battery-operated is under floating charge state.Because storage battery and electrical generator circuit are parallel-connected on the load circuit, its voltage is constant substantially, only a little more than the voltage of storage battery, by the electrical generator circuit the small amount of current of confession compensate the loss of storage battery local action, can make storage battery often be operated in charging and satisfy state and be unlikely to overcharge, storage battery can fluctuate up and down and discharges and recharges with the electrical generator voltage of system.When the light and power line voltage of load was higher, battery pack promptly charged, and heavier or power supply meets accident when interrupting when load, and battery pack then discharges, and shares part or all of load.Like this, battery pack just plays pressure stabilization function, and is in stand-by state.Also significantly prolonged simultaneously the service life of storage battery.
In the utility model, battery-driven car can be in the generating of startup spark ignition engine whenever of needs, and can supply fuel oil easily on demand.But realized not only chargeable, but also the multiple energy supplement mode of gas filed, do not worried the battery power electrically-charged nowhere multi-mode electric energy drive system battery-driven car that descends.
The beneficial effects of the utility model are:
1, this car is compared no mechanical transmission system of common fuel combustion vehicle and linked system, and is simple in structure.Cooperate dynamical brushless, permanently excited direct current motor to drive by dynamical high frequency generator and have more high energy efficiency.
2, this car can adopt fuel oil and two kinds of energy arbitrary way of electricity, replenishes more convenient.
3, adopt high frequency generator and permanent-magnet brushless DC electric machine in this scheme, have simple in structure, advantages such as volume is little, in light weight, efficient height.
4, because simple in structure, in light weight, can adopt the smaller power electrical generator can provide enough electric energy in order to drive, and can drive with pure storage battery, pure generator for electricity generation and storage battery and the multiple powering mode of electrical generator parallel powering, not only enough power can be provided but also can adapt to different use needs, energy savings.
5, the combustion engine of electrical generator partly carries electric starting system, need not to add in addition mechanically aided part, makes the electrical generator rotation to drive internal combustion engine start for the power supply of electrical generator short time with control circuit.
6, this electricity Starting mode is compared the dynamo-electric start-up mode of existing internal combustion, have simple in structure, volume is little, lightweight characteristics.
