Abstract

Various electric motor systems are provided to minimize irradiation of harmful (or first) electromagnetic waves. More particularly, an electric motor system is provided with one or more counter units which minimize irradiation of such harmful (or first) waves by suppressing such waves to (or toward) their sources and/or by emitting counter (or second) electromagnetic waves capable of canceling a desired portion of the harmful (or first) waves. Such counter units may then be incorporated into various locations for opposing magnetic poles of basic rotor units and/or basic stator units of the system. Various methods are also provided to minimize irradiation of such harmful (or first) waves by suppressing the harmful (or first) waves toward their sources and/or by canceling such harmful (or first) waves with the counter (or second) waves.
