This course provides learners with a solid guide to the principles and techniques of winding. Are you having difficulty understanding the construction of direct current (DC) generators? Do you want to be able to quickly identify the basic components and working principles of a DC machine? Then this course is for you! The types and circuit descriptions of DC generators will be discussed and you will also analyze the terminal identification of a DC compound motor in practical terms. Learn about some of the causes of damage to DC machines and the rewinding of field coils as a possible solution. Learners will be taught the key tools and materials as well as the procedures to rewind a DC motor field coil. Learn about the theory, application and two major types of armature winding. Study the procedures and methods for efficient rewinding of the armature coil of a DC machine. 

Furthermore, the material discusses the operating principle of induction motors and the double field revolving theory in developing running torque. The procedure to identify the terminals of a single-phase induction motor are outlined. Study the requirements and procedures used in rewinding a split-phase type motor. Learn about the requirements and procedures for rewinding ceiling and table fans. You will also explore the principles of operations of a three-phase induction motor and the production of rotating magnetic flux by three-phase currents. The identification of the terminals of a three-phase induction motor will be explained. See the procedures required to rewind a three-phase IM single layer wound motor and a three-phase IM double layer winding motor. Learn about the polarity test of the induction motor by the search coil and the unbalanced current test methods.

Lastly, the basic working principles and the terminal identification of a transformer are covered. If you want to master rewinding the coil of a small size transformer, this course is for you. Moreso, topics such as the working principles, advantages and the phasing-out test of a three-phase transformer will be analyzed extensively. You will learn about the different methods available for transforming three-phase voltage to higher or lower three-phase voltages. Taking this course gives you insight into the application of the dot convention with reference to the input voltage polarity in the primary winding. Learn about the additive and subtractive polarity including the application of the right-hand thumb rule. This course will greatly benefit electrical engineering students and electrical technicians who have an interest in motor winding principles and techniques.
