- ▶Motor Fundamentals CheckQuiz on motor basics, efficiency classes, and selection.5 min
02Variable-Speed Drives & Control
- ▶Why Variable-Speed Drives (VFDs)?How VFDs reduce energy by matching load to speed (not just on/off or dampers).10 min
- ▶VFD Applications & SavingsPumps, fans, compressors: where VFDs save the most, and typical payback.10 min

03Electrical Energy Management
- ▶Power Factor ManagementWhy poor power factor costs money, and how to improve it (capacitors, right-sizing).10 min
- ▶Managing Electrical Demand & PeaksDemand charges, load shifting, soft starters, and reducing peak draw.10 min
- ▶System-Wide Motor OptimizationOversized systems, poor load matching, and practical retrofit strategies.9 min
- ▶Capstone: Motors & Drives DiagnosticsHands-on: work out load factor, affinity-law savings, power factor and payback, then diagnose and decide on eight real motor call-outs.25 min
- ▶Electrical Management CheckQuiz on power factor, demand management, and system optimization.5 min
