Original Abstract
The contribution deals with a construction of a higher electric scooter with a low-voltage asynchronous drive. Basic electrical and mechanical parameters are mentioned. An attention is paid to the mechanical construction – batteries, inverter, motor, gears. Further used number of poles of the induction machine, its size and voltage-frequency relations are discussed. The digital control system of the power 3-phase inverter with MOS-FETs is briefly described. A control algorithm realising the torque control with a optimum efficiency in a wide range of torque and speed is proposed. Reached user parameters of the scooter are presented. Main problems and furhter developmentr tasks are noticed in the conclusions.
