AC Motors: Induction Motors

  • Online

Induction machine has been called the workhorse of the industry. Owing to their simple and rugged construction and low requirement for maintenance, this machine has been considered as a strong candidate for automotive traction. This module will present the fundamental concepts of induction motors. It will discuss the components of the machine, constructional details and control. Topics covered include: Components of an Induction Motor; Wound rotor and Squirrel Cage Induction Motors; Torque-speed characteristics and concept of slip; V/F Control Strategy and Field Oriented Control.
