INDUCTION GENERATORS

The Commander 400 utilizes a brushless Asynchronous Induction Generator to convert mechan- ical energy into electrical energy. The following is a brief description of an induction generator.

The induction generator is an induction motor driven above the synchronous speed. The rotor conductors pass through the magnetic field of the stator in a direc- tion that converts mechanical energy into electrical energy. Typical alternators (synchronous generators) are not self-excited. An induction generator must be connected in parallel with an electrical system that pro- vides out-of-phase current or reactive power for excita- tion. The capacitors used in the Commander 400 pro- vide the same reactive power that an induction motor would use for power factor correction. In fact, the amount of reactive power used by an induction gener- ator is equal to that used by an induction motor of the same size.

To summarize, the stand-alone induction generator used in the Commander 400 converts mechanical energy into electrical energy. The electrical energy supplied by the capacitors is transferred magnetically to the rotor. Mechanical energy is supplied to the mag- netized rotor in the form of torque and rotational speed. The majority of this energy is magnetically delivered to the stator weld coils.
