Fundamentals
Foundational modules across electrical theory, control theory, and motor and drive systems. Each sub-group is independently navigable and the modules are short, outcome-focused, and cross-linked into design, implementation, and verification references.
Scope: Prerequisite concepts before doing design work or field engineering. For applied workflows see Design, Implementation, and Verification.
Sub-groups
Electrical Fundamentals
Electrical quantities, Kirchhoff's laws, series/parallel circuits, equivalent-circuit methods, passive components, diodes and transistors, conductor ampacity, IEC earthing systems.
Control Systems
Control theory overview, PID foundation/intuition/industrial, control loop architectures, machine state model, interlocks and permissives, multi-axis coordination, async faults in distributed systems, servo tuning, vibration and resonance, deterministic vs non-deterministic control.
Motors and Drives
AC vs DC motors, induction motor basics, DC motor basics, BLDC/EV/drone motors, motor nameplates/slip/torque, motor control methods, motor-VFD equations, motor family comparison, VFD fundamentals, servo drive fundamentals, servo feedback/inertia, VFD/servo architecture, motor efficiency and losses.
PLC Software
IEC 61131-3 languages (LD/FBD/ST/SFC/IL), program structure and POUs, state-machine design, and safety application patterns.
