The AC/DC Motor Theory course was specifically developed for electricians and electronic technicians as well as for the multi-craft training needs of process and manufacturing facilities. This course consists of 11 interactive, on-line lessons that address AC and DC motor theory.
The first lesson identifies the components of an AC motor and explains their functions. Basic magnetic principles, sine waves, methods of increasing magnetic flux in a conductor, and how a rotating field is created in an AC Motor are presented.
The second lesson explains synchronous speed and how to calculate it. The lesson demonstrates the relationship between phased current and rotor spin and induction and its effect on a rotor. Slip and how to calculate slip using its formula are also covered.
The third lesson defines and explains the components and functions of various three-phase motors. The lesson also defines torque and explains its role in motor operation.
The fourth lesson defines and explains the components and functions of externally excited motors, starters, and variable speed drives. There is also a review topic to reinforce the information covered in the lesson, Three-Phase Motors – Part 1.
The fifth lesson trains the participants to distinguish single-phase motors from three-phase motors. Split-phase motors and capacitance start motors are discussed.
The sixth lesson introduces the learner to DC Motors and their basic components.
The seventh lesson introduces participants to DC motor theory.
The eighth lesson demonstrates armature reaction, compensation, and induced voltage.
The ninth lesson instructs the participant in the design of series wound, shunt wound, and compound DC motors and how they work.
The tenth lesson instructs the student in the design of permanent magnet, universal, and brushless DC motors and how they work.
The final lesson trains participants in starters, rotation direction, speed control, and drive controls of DC motors.
