Two-phase excitation linear motor

A two-phase excitation linear motor, comprising:

• two single coils forming one pole to continuously generate magnetic forces time a predetermined phase interval thereon, said two single coils being placed separately, the magnetic forces linearly driving a moving body, wherein
• said single coils individually comprise two sub-single coils formed as an approximately rectangular ring-like shape where two sides of said rectangle opposing to each other function as a pair of effective conductors for contributing to generating a thrust force for the moving body of the linear motor, and the other two sides opposing to each other function as a pair of connecting conductors for connecting between said effective conductors,
• each of the single coils comprises two sub-single coils each formed as an approximately rectangular ring-like shape where two sides of the rectangle opposing to each other function as a pair of effective conductors for contributing to generating a thrust force for the moving body of the linear motor, and the other two sides opposing to each other function as a pair of connecting conductors for connecting between the effective conductors, and
• the two sub-single coils are integrated into one body such that one of the pair of effective conductors of one sub-single coil is interposed between the pair of effective conductors of the other sub-single coil, while the two sub-single coils are connected to each other in series to form one connected-single coil and the two connected-single coils are separately arranged as said single coil for forming one pole.
