This lesson covers the process of designing induction machines, focusing on the initial design data, sizing equations, and stator core design. It explains the importance of selecting the type of machine, rotor, and standards to follow, as well as the basic specifications such as output power, efficiency, torque, speed, and number of phases. The lesson also discusses how to calculate the main dimensions of a machine, including the inner diameter of the stator, length of the core, and outer diameter of the stator. It further delves into the selection of magnetic loading and electric loading values, the calculation of the number of slots, and the choice of winding type. An example of designing a high power machine is provided for better understanding.
