We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Electrical Machines - II

This learning track covers a comprehensive understanding of electrical machines, focusing on inductance, single conductor motors and generators, operation of electrical rotating machines, rotating machines and coils, coil distribution, three-phase balanced winding, rotating magnetic fields and motors, three-phase induction motors, cage type induction motors and circle diagram, operation of three-phase induction motor and introduction to single phase induction motor, understanding single phase induction motors and synchronous machines, and understanding operation of synchronous machines. For instance, learners will delve into the principles and operations of three-phase induction motors, single-phase induction motors, and synchronous motors. They will explore the concept of self and mutual inductances of coupled coils, the operations of a single conductor motor, the construction of electrical rotating machines, the role of coils in rotating machines, the concept of coil distribution in electrical machines, the concept of double-layer three-phase balanced winding, the application of rotating magnetic fields in motors, the workings of a three-phase induction motor, the study of cage type induction motors, the process of drawing the circle diagram of a three-phase induction motor, the analysis of single phase induction motors, and the operations of synchronous machines. This learning track provides a detailed understanding of the fundamental principles and operations of electrical machines.
