In this work a design and selection methodology for seamless integration of different components of the powertrain based on Multicriteria Decision Making is proposed. This paper describes powertrain selection process involved with electric city bus. First, all possible drivetrain classification are done based on number of motors used, their position and energy sources. For each of drivetrain obtained,...
In most conventional EV applications, a central high speed electric motor is mechanically coupled to the wheels by a single speed reduction gearbox and a mechanical differential. An innovative alternative utilizes low speed, high torque, gearless, electric motors, mounted completely inside the rim of the wheels, to provide instantaneous torque and eliminate driveline transmission losses. These in-wheel...
This paper describes the development of a basic permanent magnet disc motor (PMDM) simulation model for MATLAB/SIMULINK transient analysis. The PMDM model consists of SIMULINK blocks that can be easily implemented in a real-time test environment in order to investigate all different transient regimes of the motor. The simulation drive model is consisted of a PMDM model and a pulse width modulated...
Electric motor is key part in electric vehicles including hybrid electric vehicle, fuel cell electric vehicle and battery electric vehicle. Wide torque-speed range and high reliability are needed of the motor applied in electric vehicles. Novel hybrid switched reluctance motor is developed. It combines features of robust as switched reluctance motor and that of high efficiency of permanent magnet...
