It is required to design a DC motor to run a small size electric vehicle to be
used inside an airport building to help the transportation of needy people.
The vehicle is supposed to carry a maximum of 4 persons at the full load
speed of 60 Km/hour. The engine is driven by a 200 V battery system
capable to energize the motor for 120 Km before being recharged. The
efficiency of the motor must be between 85 to 90 percent. The motor shaft
diameter is expected to be within (0.2 to 0.4 m). Give the size of the
battery required in AH (Ampere Hour). Choose and estimate all the design
characteristics of the motor. Finally display all the power flow diagram
results including efficiency and speed regulation of the motor. State all
assumptions taken.
