Magnetic Signature of Brushless Electric Motors
2006
Clarke, David
Brushless electric motors are used in a number of underwater vehicles. When these underwater vehicles are used for mine clearance operations the magnetic signature of the brushless motors is important. The magnetic signature of two models of brushless motor designed by the Kollmorgen Motion Technologies Group for use in submersible systems were examined. Magnetic mapping around the motors was performed so the influence of the individual elements of the motors could be isolated. The major component of the magnetic field was determined to be due to the shaft and rotor section of motor.
