Electric Drives
The attempt to equip motor vehicles with electric motors dates back to the past century. Around the turn of century for example, 15,000 electric-passengers cars were already registered in the United States. The fundamental design of an electric powertrain is shown in the figure.
Energy electronics which guarantee the control of the drive is interconnected between the energy source, the battery and the energy converter, the electric motor. In electric vehicles, the Direct-Current (DC) drive is traditionally the most widely used standard drive. The energy supply for an electric vehicle is generally based on direct current. The possibility of simple adjustment by cost-efficient power electronics establishes the direct-current motor as an economically viable solution.
