The electric car differs in operation from the regular gasoline car in many ways. First there is no internal combustion engine, there is no exhaust pipe, there is no fuel tank and the batteries are charged by the motor and not the alternator. There is another major difference in the design as well. This is in the area of the transmission.
In a conventional car, the transmission system is based on the gasoline engine. This means that power transfer from the engine to the back axle or the front axle will go though a series of mechanical gears till the wheel move from one speed to the other. In the electric car it is different. As the electric car uses batteries and motors for motive power, the engine would not be available to provide the force needed for the car to move.
There is a device called the adapter plate instead. This component will mount the electric motor of the electric car to the transmission of the old car and the clutch of the electric car. The purpose is to transfer power from the gears to the wheel in a smooth and uninterrupted manner. To achieve this, the adapter would have to be precisely made from a set of patterns. Actually, what we call the adapter plate is a combination of four main parts – It is made fro aluminum so it can resist heat and the will fit into the space that was originally meant for the flywheel in conventional cars.
The hub for the plate is made from steel fro extra strength. It is so made so that it can provide high torque for the car to carry more load or move uphill easily.
Adapter plates are made by highly specialized mechanical workshops due to the need for extra precision.
