Scholarcy highlights

  • The induction motor is known as the workhorse of industry and is a great invention of Nikola Tesla
  • This chapter aims to develop the basic mathematics behind the rotating magnetic field generated by the stator winding
  • It introduces a squirrel-cage rotor construction, which results in the generation of torque within the machine
  • The machine is operating on the principle of induction of voltages and currents onto the rotor by the spinning magnetic field of the stator — essentially, it is a transformer with a spinning secondary winding
  • The steady-state operation of the machine is analyzed using the equivalent circuit in order to generate the electromechanical characteristics of the machine
  • The induction machine is characterized using the no-load and locked-rotor tests to determine its equivalent circuit parameters
