Concept Sequence (Updated Spring 2023)
- Electromagnetic Fields
- The presence of current in a wire results in an electric field surrounding the wire.
- The electric field in 1 possesses a polarity
- If the electric field exists within a magnetic field, the polarity of both can result in push-pull behaviour.
- Commutators can be strategically positioned to rapidly and continuously reverse rotational polarity in support of perpetual push/pull action.
- Drive (Power)
- Current and Voltage
- BJTs, MOSFET (IRF520), Darlington Pair (TIP120)
- Collapsing EM Fields: Flyback (Snubber, Shunt) Diodes
- Common Ground uniting Drive and Control Supplies
- Control (MCU)
- Low-Side (N) vs High-Side (P) Switching
- On/Off
- Speed
- Direction (DPDT Switch/Relays, H-Bridge)
