Lesson 15 40 mins
MOTORS (10 mins)
Introduce motors and different types of motors in this topic |
Motors are machines which convert electrical energy to mechanical energy. Drones require motors to create a necessary thrust during flight.
HOMOPOLAR MOTOR EXPERIMENT (15 mins)
Use this experiment to show how a basic motor works. It uses neodymium magnets, a AAA battery and a copper coil. Watch the video to understand the working. |
➔ Build and show to explain how a motor basically works
➔ Refer: DIY: How To Make a Simple Homopolar Motor
WORKING OF MOTORS (15 mins)
After understanding basic homopolar motor, show the following video to understand how modern motors work. A suggestion would be to show the video till 2:36 only as it gets more complicated later. |
