because they are easy to be control on speed and torque. The example of using DC
motor in transportation is electric train.
By giving DC electric voltage in directly will cause the speed of electric
train shock suddenly because of that it needs speed control machine to control the
speed automatically.
The basic structure of this machine is base on the clip voltage control at
the motor. By processing the voltage control by step will make the speed of the
motor increase smoothly. The voltage change is control by the computer until the
speed matches from we want.
From the research, the motor speed can spin more smoothly.
