This training series is designed for engineers, procurement teams, maintenance professionals, and technical sales specialists.
Chapter 1
An electric motor is a machine that converts electrical energy into mechanical energy, almost always delivered as a rotating shaft. Electricity goes in; the shaft turns; the shaft runs a machine such as a pump, fan, compressor…

Chapter 2
This is the chapter that separates a salesperson from a sales engineer. Customers almost never say “I need a squirrel-cage induction motor.” They say “I need a motor for my compressor,” or “I need a replacement for this pump…

Chapter 3
This chapter looks at the physical parts of a common industrial three-phase squirrel-cage induction motor: what each part is, what it does, and — crucially for a seller — what it means in quotations, spare-parts lists, and…

Chapter 10
This is where you become a trusted sales engineer rather than someone who forwards quotations. Customers don't only ask “how much?” They ask “why TECO instead of WEG?”, “can ABB be replaced with TECO?”, “is this Chinese motor…
