“…Some of these proposals use computers and simulation packages [2,3], whilst most of the work which advocates the use of purpose build hardware teaches only DC motors [4,5]. Indeed there seems to be a complete absence of experiment based teaching material for three phase inverters driving a three-phase induction motor.…”

The hazards associated with high voltage three phase inverters ond the rotating sha@s of large electrical machines have resulted in most of the engineering courses covering these topics to be predominantly theoretical. This paper describes a set of purpose built, low voltage and low cost teaching equipment which allows the "hands on I' instruction of three phase inverters and rotating machines. By using low voltages, the student can experiment freely with the motors and inverter and can access all of the current and voltage waveforms, which until now could only be studied in text books or observed as part of laboratory demonstrations. Both the motor and the inverter designs are optimized for teaching purposes, cost around $25 and can be made with minimal effort.
