Driving Train, Motor, and Control Systems - Coursework Example

For the electric skateboard, it is expected that the front pad will be used for acceleration while the rear pad shall be used in the braking system. Both pads will be connected at the center that shall comprise an electric circuit board to be used in powering the system, as shown in the figure below.

This shall be wrapped together in a box with the batteries and connected to the front and rear wheels.

            Normally, the controller will control the voltage coming from the batteries to the motors, except for when batteries are dead. Therefore, the regenerative power shall be used in controlling the voltage flow which will allow for the recharging of the batteries in a vice versa way without needing to plug the batteries into an external power source. The regenerative technique to be employed in this design shall work through a rotational basis of its mechanical energy; hence, re-populating the batteries.

            During the rotational process of the motor wheels, there is mechanical energy is released. Through the regenerative technique, this energy shall be channeled back into the battery system and into the motor through the axles. Therefore, as the mechanical energy goes through the axle and motor again, it causes a rotational movement inside of the motor; thus, forming an electrical field in the motor. The created electric field will then push back the mechanical energy to the batteries through the controller. In this stage, since the controller was responsible for gauging the electric flow out of the batteries, it would also regulate the inflow of the mechanical energy caused by the rolling of the wheels during skating, into the battery system, by raising the level to feed the batteries again.

            Taking on the form of a PID system, the controller can further take on the form of a remote sensor gadget clutched in the hands of the user to apply the start of the board, acceleration, and deceleration speeds of the board. The standard recharging time for the batteries would be approximated as 20 minutes, although being a continuous process, it would occur intermittently with each drop in battery power. Additionally, the controller is essential in this electrical skateboard given that it would be a replacement to the regular movement of the feet on the ground by skaters when required to propel their boards. Extra-ordinarily, this skateboard and its component of having a remote controller would be essential in its marketing perspectives as such kind of a board would be used to spy on hostile grounds, when mounted with remote cameras (Hoena 102-106).

This controller shall apply a regenerative technique that shall apply an automatic braking system to allow for an easy stoppage of the board in case of imminent dangers. Given that the rear pad shall be used for braking, while the front for acceleration, a user of the board would be able to enjoy usage due to the automatic transmission of the controller into the weight sensor system.

The technique for the weight sensors shall determine the weight of the skater and use the same in controlling the motors, depending on the ends of the skate to which the heaviest force is applied. For this, the potential meter shall be used in making the paddles so that by pressing on the front paddle (for acceleration), one would be able to upsurge the speediness of the skateboard (Hoena 122-126). Alternatively, when the rear paddle is pressed, the weight sensor shall relay to the controller system that shall subjectively lower the motor system, hence, repelling further forward movements of the skateboard; thus, acting to break the board. By pressing on the front paddle, the resistor in the main electric circuit board shall open and allow more flow of the voltage from the batteries; thus, causing the speeding up.

To avoid complexities in control, the rear paddle used for braking shall be connected to another circuit so that it regulates the outflow of voltage so that motor speed is reduced causing the skateboard to halt. Hence, the control system will boost the motor power in conjunction with the weight sensors.
