General Concepts (Updated Spring 2023)

1. 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.
2. 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
3. Control (MCU)
   • Low-Side (N) vs High-Side (P) Switching
   • On/Off
   • Speed
   • Direction (DPDT Switch/Relays, H-Bridge)
4. ACES' Electromechanical Devices Explored
   • Solenoid (Linear) (Sparkfun ROB-11015)
   • 5V Relay ()
   • DC Motor (Rotational) (Sparkfun ROB-11696)
   • Servo (Angular) (Standard (FS5103B) vs Continuous)
   • Stepper (Incremental) (MOT-28BYJ48)
