036. How Motors Work For Beginners (Ep 1): The DC Motor
- Video Outline
- Permanent magnet DC motor (the main discussion in video) - found in a hand drill
- - uses a permanent magnet (stater) and a coil of wire to carry the current
- - these motors have "brushes" that maintain an electrical connection (commutator)
- - Wikipedia: Brushed DC electric motor
- Universal motor - found in a blender or vacuum cleaner
- - these can run on both DC or AC input voltage and instead of having permanent magnets, they have 2 coils of wire.
- - [https://en.wikipedia.org/wiki/Universal_motor Wikipedia: Universal motor
- mini induction motor - found in a microwave (fan) or washing machine (water pump)
- mini brushless DC motor - found in a computer fan
- Induction motor (single phase or three phase)
037. How Motors Work for Beginners (Ep 2): The Generator and Universal Motor
- Video Outline
- - More about the permanent magnet DC motor
- - Intro to the universal motors
- universal motors are not generators since they do not have a permanent magnet.
- - Quick demo of inductance motors
038. How Motors Work for Beginners (Ep 3); Three Phase Induction Motors
- Video summary
- - Demo of induction motor
- - 3-phase motor (mainly)
- - then single phase.
039. How Motors Work For Beginners: Single Phase Induction and Shaded Pole Motors
- Video Summary
- - demo single phase induction motor
