In previous articles we have observed how to decide on a motor and a Variable Velocity Push (VSD) for an electrical automobile. In خرید الکترو موتور داکت اسپلیت will explain how to select a automobile for your electric motor. You may possibly be wanting to:
1.Transform an current auto to electric operation, employing a battery, or
2.Change an present auto to electric procedure, making use of the Talbot Electrical grid connection, or
3.Construct a auto from scratch for electric operation, utilizing a battery, or
four.Construct a auto from scratch for electrical procedure, connecting to the electricity source grid.
Whichever it is, we will display you how to go about it. Assuming that your decision is 1, you could have an outdated auto with a worn out gasoline motor that you would like to convert to electric powered, or you may be hunting to obtain an previous automobile from a breaker’s property. If the latter, bear in mind that more mature technological innovation vehicles are simpler to operate on. Consider to locate a vehicle that is fairly seem except for the motor, which latter will be discarded. If it seems a little bit shabby you can easily have it reupholstered and repainted right after conversion. Then you will have a good-looking electrical automobile that could last you a life time. If you want it as a nearby runabout select a little vehicle. You can use a smaller sized battery and motor. Make a decision on the best velocity that you want. That will establish the measurement of motor. The typical gentle auto requires only 5kW to maintain a pace of 60km/h (37.3 mph) on a degree highway. If you want to do 100km/h (62.1mph) you will want a motor of 15kW. On my web site you will locate a list of appropriate 400Hz motors ranging from five.6kW up to 150kW. My company does not market these. If you send out me an electronic mail from my web site I will explain to you exactly where you can get them.
If your option is two you will not require a big lithium-ion battery. Your power will occur from the grid. In an emergency, your regular twelve volt battery will be ample. Whichever case you pick, the very first issue is to eliminate the gasoline engine from the vehicle. The gearbox (“transmission”) might be retained. On a 400Hz supply these motors rotate at speeds of eleven 400r/m to twelve 000r/m, relying on load. Several of the motors are available with a reduction equipment. Various ratios are accessible. Choose one particular that offers a reduction of between 2:1 (for a high best velocity) and 4:1 (for a decrease best velocity). Retaining the car’s unique transmission will permit outstanding acceleration and the potential to climb steep hills. Some of the motors are water cooled. Need to you use a single of these, keep the car’s radiator. Be part of hoses among the radiator and the motor, with an electric drinking water pump in amongst. This will offer exceptional cooling and let the rated energy of the motor to be exceeded. It is a good idea to place thermistors in speak to with the stator windings to alert of excessive heat construct-up. A a few-period induction motor has an efficiency of 90% or much better. Thus only 10%, at most, of the input vitality is manifested as heat. Evaluate this with a gasoline engine, which at 60km/h has an efficiency of around 14%, which means that 86% of the energy of combustion of the gas has to be taken out by the radiator and exhaust system. This kind of successful cooling will permit the motor to be operated continuously nicely previously mentioned its rated energy.
If you intend building a vehicle from scratch, think about creating the entire body of spheroidal form, like that of the product “69zulu.” Make it in two halves in fiberglass reinforced epoxy resin and be part of them. This will give you a quite light automobile with a minimal drag coefficient. A 5kW motor in every wheel fairing will give a lot more than adequate efficiency. A 5.6kW motor is only 6 inches (150mm) in diameter and nine.5 inches (241mm) extended and weighs only six.8kg (fifteen lb). Making use of individual motors on every wheel eradicates the require for a differential.
In order to be ready to manage the speed of your automobile you will want a VSD. If you are an electronic whizkid you can make your personal. Or else there are many types available commercially. However, most of the latter are for 50 or sixty hertz. If you plan to use a battery, you will require one particular of about 280 volts in get to get two hundred volts three-stage right after inversion.
