Electric Kart

This is a teaching and extension project which the purpose of studying the efficiency of the electrical energy’s use to support a Kart and it also includes the analysis of Electromagnetic interferences and the relations of generated forces by an electric motor to a mechanic energy transference.

Structure

A structural base and an electric propulsion compose the electric kart. To make the structural base several analysis and simulations were carried out to ensure the stability and rigidity. Whilst the electric porpulsion area of the system contains a batteries bank, a frequency inverter and a brush-type DC motor.

Energy supply

All vehicle needs a system to receive the energy and then transform it in movement. Nowadays, the most common way is transforming the Thermal energy (combustion) into mechanical energy but in this project studies was used the electric one where the batteries bank is supplied by an voltage source.

Electromagnetic Compatibility

When there are devices in electrical and electronics systems is safe if they do not make interference in the operation of the others with electricmagnetic noise that they will emit. This process calls electomagnetic compatibility because there is acceptance among the components. The operation can be affected for many reasons such as the electromegnetic noises can unleash any wrong operation that would not be activated at that time because it is really sensitive and the noise can make incorrect data readings by the system and the interference would prevent some important operation. For that reason it is necessary that the system has the electromagnetic compatibility.

In this project it can be very dangerous because there is a brush in the motor of the system which is very common in DC motors and it produces a plenty of electromagnetic noises what can affect the embedded electronics of the vehicle.
