  • Electric Motor
    Publication number: 20140312745
    Abstract: An asymmetric brushless direct current (DC) motor having a stator having a plurality of magnets and a rotor having a plurality of armatures where the vector sum of magnetic forces between each armature and each respective magnet is zero at every angular rotation position of the rotor with respect to the stator in the motor's non-energized state.
