How To Control 3 Phase Induction Motors
Three phase induction motors are the workhorse of industry. It
has been estimated that 70% to 80% of all electricity in the world is
consumed by these motors. They are truly elegant machines in that
there are no moving parts except the rotor, and there are no brushes,
commutators, or slip rings to wear out.
This computer program on CD explains How To Control 3 Phase Induction Motors
in 23 screens of PowerPoint text,
graphics, and pictures. The program explains:
