Practical Electronics & Circuits 101 – Electric Motors

The 13th video in the series Practical Electronics & Circuits 101, where I explain the fundamentals of circuits with a focus on using this knowledge for actual projects. The topic of this episode is electric motors and goes into detail on brushed DC motors, brushless DC motors (BLDC), 3 phase AC induction motors, steppers, and servos. I also go over PWM, motor drivers, and controller circuits. Stay tuned for a future video where I'll give an in-depth tutorial showing how to control some of these motors using hardware PWM with a Raspberry Pi and Python.

A few of the motor drivers (H-bridges) shown in this video:
