It is required
to design the DC motor dedicated to carry two wagons underground railway train.
Each wagon is supposed to carry a maximum of 20 persons. The power utility is
supplying the railway by 700 V DC source capable to deliver enough current. The
train should reach a full load speed of 100 Km per hour. The efficiency of the
motor must be between 85 to 90 percent. The motor shaft diameter range is (0.6
to 0.8 m)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.
Give all assumptions taken.
