IE 140 - AC/DC Machines

Credit Hours: 3

Topics include: review of AC voltage and current phase relationship and computations of reactance and power; transformers and transformer applications; introduction to generators and motors; single-phase motors; three-phase alternators and motors; DC motors and generators and AC and DC motor control fundamentals. Experiments include: AC phasor computations, single-phase transformers, three-phase wye and delta connected transformers, single-phase AC motor characteristics, three-phase alternators, three-phase motors, DC motor and generator characteristics, simple motor starter and control circuits.
