General Description

The Modular Application (AC Motors), "AEL-AI12", has been designed by EDIBON in order to instruct the students about the most important operations of alternating current motors.

This application consists of several elements which allows the user realize logic control circuits in order to manage the motors included in this unit: three-phase induction motor of squirrel cage, single-phase induction motor with starting and running capacitor and Dahlander motor.

At first, the student gets theory knowledge about how the motors described before work. After that, the student will be ready to wire logic control circuits to start the motors by different ways, working in forward and reverse speed of the machine, breaking the motors and study several protections.

Optionally several AC electrical machines are offered in this application such as three-phase induction motor with wound rotor, three-phase induction motor of squirrel cage with two speeds, single-phase induction motor with starting capacitor, single-phase motor with split shift, three-phase reluctance motor and single-phase shaded pole motor.
