Title:
ADAPTIVE CONTROL ARCHITECTURE FOR ELECTRIC MACHINES
Document Type and Number:
WIPO Patent Application WO2004073157
Kind Code:
A3
Abstract:
A distributed architecture for electric motors and generators. This distributed architecture motor can deliver high power at low voltage and low phase current. It works by distributing total current across several "phases," or electromagnetic circuits of the motor. That creates several advantages. These motors can deliver the high power needed by an electric car at 50 volts or less, which is safer for humans. They improve safety by allowing a motor to operate in an emergency even when one or more phases has a fault. Low voltage motors in electric vehicles allow batteries and fuel cells to have fewer cells. The low voltage and distributed current makes heat easier to handle. The distributed architecture lowers cost by allowing cheaper power electronics to be used. The distributed architecture allows smaller, lighter motors to be made with light wiring, switches and connectors. In addition, it opens the path to lower cost battery and fuel cell technologies, simplified battery and fuel cell management, and wider packaging options.
