You wish to create an automated cart that can be easily programmed to move back and forth precise distances across the factory you work in. Which type of DC motor would be best used to drive the cart\'s wheels for this application? Explain. A DC servo motor A pulsewidth modulated standard DC motor A DC stepper motor

Solution

A DC stepper motor is used as drive to cart wheels because no other feedback or sensor is required to find the precise distance.

A DC servo motor with H-bridge control can be move back and forth but cannot be stop precise distance with this simple circuit it requires another controller to trace distance where to stop.

A pulsewidth modulated standard DC motor is used to control speed of card which required another sensor circuit to measure distance where to stop.

DC stepper motor can be programmed easily and can be stopped at precise distance as it moves in steps, if were given steps required to reach a certain distance , it will automatically stops at required distance.
