Selecting optimum voltages for high-power electric machines for hybrid and electric aerospace
Recently, electric motors and generators rated from 200kW to 1MW with DC voltages ranging from 500V DC to 4,000V DC have become one of the key technologies supporting the goals of hybrid electric propulsion, such as driving overall system efficiencies as high as possible while reducing system weight by increasing the power density and system simplicity. This presentation compares the advantages and disadvantages of different high voltage DC levels used in electric generators and motors and distribution equipment. Honeywell has an unparalleled generator and motor range for aerospace, based on more than 100 years of innovation and product development, ranging from hundreds of watts to 1MW.
