SYSTEM AND METHOD FOR INCREASING OUTPUT HORSEPOWER AND EFFICIENCY IN A MOTOR

摘要

A system and method are provided to increase the horsepower of an induction motor 106. One technique for increasing the horsepower of a motor 106 is to connect the motor 106 to a variable speed drive 104 that is providing an output voltage and frequency greater than the standard line voltage and frequency. The connection of the variable speed drive 104 to the induction motor 106 enables the motor 106 to be operated in constant flux or constant volts/Hz mode and provide a greater output horsepower. Another technique for increasing the horsepower of a motor 106 is to use a dual voltage motor configured for lower voltage operation and then provide the motor 106 with the corresponding voltage and frequency for higher voltage operation.
