7.3.1.a. DC Motors

Try these first

1. 1.

   What type of motion do DC motors provide?

   Hint

   Think about how a wheel rotates.

2. 2.

   How can the speed of a DC motor be controlled?

   Hint

   What methods do we use to adjust speeds in devices?

3. 3.

   What type of motor provides continuous rotary motion?

   • AC Motors
   • DC Motors
   • Stepper Motors

   Hint

   Remember the types of electric motors we discussed.

4. 4.

   True or False: DC motors can only be used in robotic applications.

   • True
   • False

   Hint

   Consider other everyday devices that might use DC motors.

5. 5.

   Design a simple robotic vehicle that uses DC motors for navigation. Describe how you would control the speed and direction.

   Hint

   Consider how real robots navigate using their motors.

6. 6.

   Discuss the advantages of using DC motors in comparison to stepper motors for a specific application.

   Hint

   Compare continuous and discrete motions to understand the pros and cons.
