The calculation and the choice technique of an electric bolid motor according to the "Formula student" regulations
The calculation and the choice technique of an electric bolid motor according to the “Formula student” regulations has been developed. The calculation procedure of electric bolid motor power and its peak torque is given. The conditions of a motor choice according to its reliability, the correctness of motion parameters from the given figures, the speed, the quality of transients and the energy efficiency are determined. The computer model allowing to calculate the dependencies of the electric drive basic parameters on time has been shown and described. The article presents the calculation and the choice example of the electric bolid motor. Its results showed that the engine power was 42.5 kW, and the value of peak torque was 151,9 Nm. Using the characteristics of the chosen motor and the designed computer model under a certain configuration of a racing track, the dependencies of the speed and the acceleration of an electric bolid, the consumed electric power and energy can be calculated
