These handwritten notes explain the fundamentals of electrical machines in clear, simple language — perfect for diploma and engineering students. The PDF covers the difference between motors and generators, Fleming’s left/right hand rules, Faraday’s laws, motor working principle, power flow diagrams and detailed construction and working of DC machines (pole core, armature, commutator, brushes). It also includes ladder-style diagrams, important formulas, types of DC motors (series, shunt, compound) and basic speed control methods.
- Key Topics Included:
- DC Generators & Motors: Working principles, construction (Yoke, Armature, Commutator) and the significance of Back EMF.
- Speed Control: Methods to control speed like flux control, armature control and the field diverter method.
- Transformers: Principle of operation, EMF equation, construction (core, windings) and cooling accessories like the conservator tank and Buchholz relay
