It is required to design the DC motor to run a small size electric vehicle to beused inside an airport building to help the transportation of old people. Thevehicle is supposed to carry a maximum of 4 persons at the highest speed of 60Km/hour. The engine is driven by a 200 V battery capable to energize the motorfor 120 Km before being recharged. The efficiency of the motor must bebetween 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 displayall the power flow diagram results including efficiency and speed regulation ofthe motor. Give all assumptions taken
