Electricar is the controller.
Electric car transmission system. First given mg torque power rpm characteristics they re perfect for transportation. These motors are typically geared down to produce plenty of torque and appropriately match road speed. For home built electric cars the exact types of motors used vary considerably.
An internal combustion vehicle has a multi speed gearbox with numerous. Of course this doesn t mean that electric cars couldn t have gears but they aren t necessary. Often the term 5 speed transmission refers simply to the gearbox that uses gears and gear trains to provide speed and torque conversions from a rotating power source to another device.
An electric controller was added to control the ac motor. I don t get it. One of the biggest differences between electric cars and their conventional counterparts has to do with the drivetrain.
This system is generally also called hydramatic transmission. Automatic transmission system is the most advanced system in which drives mechanical efforts are reduced very much and different speeds are obtained automatically. However they also tend to spin very fast.
A gear ration in the neighborhood of 10 1 is not uncommon. Commercially built electric cars use motors specifically designed for torque at a very wide range of speeds. The 50 kw controller takes in 300 volts dc and produces 240 volts ac three phase.
Everyone seems to be keeping the transmission in their electric car conversions. Power is necessary for cruising the most of which is developed at high rpm. A transmission is a machine in a power transmission system which provides controlled application of power.
Of course i would need to mount the motor where the tranny is now and get a part milled to connect the drive shaft to the motor. The box that says u s. If i upscale the motor why can t i lose the transmission and clutch etc.
It contain epicyclic gear arrangement fluid coupling and torque converter. At a bare minimum that at least means less shifting. In british english the term transmission refers to the whole drivetrain including clutch gearbox.
You may have the most powerful most fuel efficient engine in the world but if you don t have a transmission or gearbox then all that power will simply be for naught since there is no connection. The bmw i8 sports car for example uses a bmw two gear system and toyota s hybrids have a more conventional cvt transmission which uses a belt moving between two cones to make sure the engine. The transmission is one of the most important parts of any vehicle.
It is a series of components that actually receive power from the engine and transmit this power to the wheels of the car.
