Variable-speed electromechanical energy converter |
摘要 |
A variable-speed electromechanical energy converter includes a wound-type induction motor and a power rectifier connected to a secondary winding of the motor to convert AC power produced by the motor into DC power. A chopper is connected to an output of the power converter to control the output thereof according to a control signal and a capacitor is connected through a rectifier device to the chopper. A power inverter converts DC power stored in the capacitor into AC power which is fed back to an AC system connected to the motor. The motor includes a cage rotor disposed between a wound rotor and a rotor shaft, the cage rotor being separated from the rotor shaft by an inner gap and separated from the wound rotor by a middle gap so as to rotate independently of the rotor shaft.
