Description
Aerospace technology — in particular space flight — has encouraged and sometimes made necessary the development of new devices and the continual improvement of present devices. One new device which may offer distinct advantages over existing devices in the area of rotating machinery is a recently developed DC brushless motor. * Some of its advantages are the elimination of electronic interference, constant torque generation, simplicity of construction, and the maintenance of performance specifications over wide ranges of load, input, and environment. Notice that the elimination of EMI/RFI interference is especially desirable to on-board communication systems. Other system malfunctions have been traced to unintentionally generated stray signals. It is conceded that there were several types of DC brushless motors in existence prior to this one, but these motors all have the serious disadvantage that the rotor sensing mechanisms require more complicated circuitry.
