Machines 1 introduces the fundamental principles of electrical machines, focusing on transformers, DC machines, and basic AC machines. It covers the working principles, construction, and operation of these machines, along with performance analysis and efficiency calculations. Students learn to analyze and design circuits involving electrical machines for practical applications.
1.Synchronous Motors: principle of operation, equivalent circuit and phasor diagram,
performance characteristics and pull-out torque, starting of synchronous motors, speed
control of synchronous motors, V-curves and applications in power factor correction, testing
of synchronous motors.
2. Three-Phase Induction (Asynchronous) Machines: types, construction and principle of
operation, development of equivalent circuit, testing and parameters determination, power
flow diagram and analysis, develop torque-speed characteristics, starting of 3-phase
induction motors, speed control of 3-phase induction motors.
3. Single-phase Induction Motor: construction of single–phase induction motor, principle of
operation. Equivalent circuit and its analysis. Starting single-phase induction motors:
capacitor-start motors. Torque speed characteristics, speed control of single-phase
induction motors. Capacitor-run motor.
4. Special Motors: reluctance motors, universal motors, brushless DC motors, stepper motors
