The Motors and Microcontrollers 101 that We Should All Know!

Motors are the general components that we’re normally used in many industries, such as electronic, electrical, automobile, engineering and much more. Electric motors are the main key of converting electrical power into mechanical power.


Since the electric motors are simple and reliable machines, hence they can be found all over the place, in whatever shapes and sizes you want it to be! Don’t believe it? Well, maybe some examples will convince you here:

  • The powerful starter motor

  • Alternating windshield wiper motors

  • Intermittent-use power windows and door locks

  • The blower fan that moves hot and cold air into the cabin

  • The Tiny motors inside the CD player

However, please stick in your mind that motors are slightly tricky loads to control. Their current can be totally varied with loading, starting and stopping, where it can causing a danger to other circuit components, if you didn’t handle it carefully!

Well, you might want to carry out the eight quick motor experiments and see the result by yourself, which as:

  1. Spinning the motor to make a voltage.

  2. The motor can be used to light an LED, if you’re spinning the motor properly.

  3. The inertia keeps the rotor spinning.

  4. The Winding resistance of the motor can be measured with a multimeter.

  5. The operating current under no load is relatively small.

  6. The current required when starting the motor is larger.

  7. The stall current, when the shaft is locked is very large.

  8. A spark can be seen, when the motor is switched on/off simultaneously.

Let’s go ahead and give it a shot right now…[nerdkits]
