Abstract
The utility model discloses an electro-motive automobile with ac driving and adjustable-speed by frequency changing, which is characterized in that the direct current motor of an existing electromobile is replaced by an ac motor; the direct current of a storage battery is converted to alternating current through a commonly known speed control assembly with adjustable frequency, and the frequency conversion method is adopted to adjust rotation speed of the ac motor. The electro-motive automobile has the advantages of small maintenance load, and the energy converting efficiency of the electro-motive automobile can reach 80%; the electro-motive automobile can continuously run for 200 kilometers for one time charging, and the electro-motive automobile is very suitable for the requirement of intra cities and suburbs. When the electro-motive automobile runs downhill and brakes, the potential energy and dynamic energy of the electro-motive automobile can be converted to electric energy which is feeding back to the storage battery, and braking loss is reduced.
Description
The utility model relates to a kind of transportation and communication, is a kind of AC driving electrical variable frequency adjustable speed automobile specifically.
Known electric automobile claims battery vehicle again, adopts direct current machine to drive, and the pulse-width modulation speed governing is by storage battery power supply.This electric automobile is because ring fire appears in the commutator of direct current machine easily, and maintenance load is big, and the energy in the time of can not be descending, braking is sent storage battery back to.
The AC driving electrical variable frequency adjustable speed automobile that the purpose of this utility model is that a kind of maintenance load of design is little, energy conversion efficiency is high, can send the potential energy in descending, when braking or kinetic energy back to storage battery.
Alternating current machine and RHVC are used for traditional electric automobile, replace direct current machine and pulse wide modulation device and just can reach the purpose of this utility model.The utility model is the same with traditional electric automobile, comprise storage battery, speed regulator, motor, reduction box-clutch, wheel-car body, direction machine and brake apparatus, it is characterized in that motor adopts alternating current machine, speed regulator is made up of RHVC, alternating current steady voltage plug and control power supply, alternating current steady voltage plug is supplied with the needed operating voltage of RHVC, the rotating speed of RHVC control alternating current machine.
The utility model has following accompanying drawing:
Fig. 1 AC driving electrical variable frequency adjustable speed automobile theory diagram.
Fig. 2 inverter schematic diagram.
Fig. 3 voltage stabilizing transformer schematic diagram.
Fig. 4 regulated inverter schematic diagram.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model theory diagram.The basic composition of this AC driving electrical variable frequency adjustable speed automobile is the same with known electric automobile, comprises storage battery ［ 1 ］, speed regulator ［ 2 ］, motor ［ 3 ］, reduction box-clutch ［ 4 ］, wheel-car body ［ 5 ］, direction machine ［ 6 ］ and brake apparatus ［ 7 ］.Feature of the present utility model is that motor ［ 3 ］ is an alternating current motor, as y series motor, YL serial motors, JO
2Serial motors all can; Speed regulating device ［ 8 ］ are RHVC, as BP-6-380V-12kW RHVC, BP-6-220V-7.5kW RHVC, the difference of these two kinds of RHVC is the output AC voltage difference, is respectively 380V and 220V, and the two is three-phase electricity; Also can be single-phase electricity, but electric efficiency is lower.The voltage of storage battery ［ 1 ］ is chosen as 300V or 500V.If select the storage battery of 300V for use, can with the RHVC of 220V, the supporting use of alternating current machine of 220V; If select the storage battery of 500V for use, can with the RHVC of 380V, the supporting use of alternating current machine of 380V.The needed 220V alternating current steady voltage plug of RHVC ［ 9 ］ is also powered by storage battery ［ 1 ］, one of adoptable technical scheme is UPS, it is uninterrupted power supply (comprising control power supply ［ 11 ］), storage battery ［ 1 ］ links with UPS, the output of UPS and RHVC ［ 8 ］ link, and can guarantee RHVC ［ 8 ］ operate as normal, regulate the potentiometer knob of RHVC, the rotating speed of scalable alternating current machine ［ 3 ］ reaches the purpose of speed governing.Two of the adoptable technical scheme of alternating current steady voltage plug is by inverter (as Merck Mo Laishi inverter) direct current of storage battery to be become alternating current, then by the AC voltage regulator voltage stabilizing.The formation of Merck Mo Laishi inverter is referring to Fig. 2, and the formation of AC voltage regulator is referring to Fig. 3.Three of technical scheme is to adopt custom-designed regulated inverter (referring to Fig. 4), it is actually known Merck Mo Laishi inverter and known AC voltage regulator is united two into one, the two has common main magnetic circuit, promptly use same group of iron core, like this can weight reduction and volume, save raw material.The needed control power supply of inverter ［ 11 ］ can be selected known flip and flop generator for use, and its voltage pulse output is chosen as+5V, pulsewidth 200 μ s, frequency 50Hz.
Alternating current machine ［ 3 ］ is the same with known battery vehicle with the connected mode of reduction box, and wheel-car body ［ 5 ］, direction machine ［ 6 ］ and brake apparatus all need not changed.
Owing to adopted alternating current machine, so the utlity model has the advantage that maintenance load is little, energy conversion efficiency is high.Energy conversion efficiency when adopting direct current machine is about 60%, and the utility model then can reach 80%.When the speed of a motor vehicle in descending, when braking surpasses RHVC at that time during the pairing synchronous speed of output frequency, alternating current machine ［ 3 ］ just is operated in generating state, motor ［ 3 ］ electricity to storage battery ［ 1 ］ charging, produces braking moment by speed regulator ［ 2 ］ simultaneously.Like this, originally consume the portion of energy in brake block, be stored into storage battery ［ 1 ］ lining again and go.
Once charge about 120 kilometers of rear wheeleds of existing battery truck can travel 200 kilometers after electric automobile of the present utility model once charges continuously, can adapt to the needs of city and city effect transportation.
