Course content

4 sections • 26 lectures • 4h 25m total length

  • Introduction0:31
  • Introduction to AC motor4:54

    Explore the basics of alternating current motors, focusing on induction motors, their robust three-phase construction, wide industrial use, and common home appliance applications.

  • Introduction to Induction motor10:07

    Explore the induction motor, a three-phase asynchronous machine that powers fans, pumps, and conveyors; learn its brushless, low-maintenance design, speed control with variable-frequency inverters, and stator and rotor construction.

  • Construction of Induction motor16:56

    Explore the induction motor’s simple two-part rotor and stator, including three-phase stator windings, rotating magnetic field, and low maintenance design with a robust rotor and insulated cores.

  • Parts of Induction motor13:11
  • Parts of Induction motor_rotor and Stator6:48

    Explain how the induction motor uses a rotor conductor and a stator’s rotating magnetic field to produce rotation, reduce humming, prevent magnetic locking, and protect the rotor by managing resistance.

  • Summary4:16

    Induction motors convert three-phase ac power into mechanical energy via a rotating magnetic field created by the stator and rotor, with insulated windings, non-contact rotor, and rugged, low-maintenance design.

  • Three phase Induction motor construction8:21

    Explore the construction and working principle of three-phase induction motors, including the squirrel-cage rotor, stator, and transformer-like induction without external rotor connections.

  • Working Principle of Induction motor12:55
  • Working Principle of Induction motor12:11

    Explore the working principle of a three-phase induction motor, where a revolving magnetic field induces rotor currents to create torque; learn how swapping two supply lines reverses rotation.

  • Motor Slip2:32

    Analyze motor slip in an alternating current motor by comparing rotor speed with the rotating magnetic field at synchronous speed, and apply the slip formula to quantify the speed difference.

Requirements

Description

This course discuss alternating current motors construction and operation. At the present day the most widely used industrial motor is the induction motors. so that this course introduces a complete knowledge of three phase and single phase induction motors.

The induction motor is made up of the stator, or stationary windings, and the rotor. The stator consists of three units; outframe, stator core and a series of wire windings of very low resistance permanently attached to the motor frame. As a voltage and a current is applied to the stator winding terminals, a rotating magnetic field is developed in the stator, the rotating magnetic field induce current into the rotor bar conductor finally the rotor produce magnetic field. The interaction of the two magnetic field turn the motor to rotate in the direction of the rotating magnetic field.

The course will go into detail for the following key topics :-

  • Show  construction of induction motors

  • See how the three-phase induction motor operates and rotates

  • Discus types of induction motor parts and its function

  • Discus advantage of Induction motor

  • Discus types of induction motor rotor

  • Discus parts of induction motor stator units

  • Describe rotating magnetic field in induction motor

  • list application area of induction motor

The PowerPoint for the course, the assignment and  the unit quiz and test as well as the answer key, will be uploaded based on  trainees request.
