2.2 Linear Generator

When cars pass the speed control hump, the speed control hump moves down because
of the gravity of the cars. Due to the movement of the motor rotor, the permanent
magnet fixed in the motor and coil fixed in the following take place relative
displacement, thereby cutting the lines of magnetic induction generate electricity. As
shown in Figure 3, when the car press the speed control hump, the front sloping
offsets part of horizontal force. So that when the cars passed the middle part of speed
control hump, the linear generator's mover moves downwards with the permanent
magnet. Detailed structure of the linear generator is showed in Figure 4, Figure 5 and
Figure 6.
