<P>PROBLEM TO BE SOLVED: To realize an electric motor that rotates under a state where a rotator generates a magnetic force, is capable of generating a stable support force for floating the rotator to produce a certain gap, is easy to control, is small in size, and is low in cost and to realize a stator of the electric motor and an electric motor system equipped with the electric motor. <P>SOLUTION: A stator 11 of an electric motor, which rotates under a state where a rotator generates a magnetic force, includes: first terminals U<SB POS="POST">m</SB>, V<SB POS="POST">m</SB>, and W<SB POS="POST">m</SB>for connection of an electric motor current generation part 13 for generating an electric motor current for generating a rotation torque of the rotator; second terminals U<SB POS="POST">s</SB>, V<SB POS="POST">s</SB>, and W<SB POS="POST">s</SB>for connection of a support current generation part 14 for generating a support current for generating a magnetic force in a radial direction of the rotator; first windings U<SB POS="POST">ms</SB>, V<SB POS="POST">ms</SB>, and W<SB POS="POST">ms</SB>whose one ends are connected to the first terminals U<SB POS="POST">m</SB>, V<SB POS="POST">m</SB>, and W<SB POS="POST">m</SB>and the other ends are connected to the second terminals U<SB POS="POST">s</SB>, V<SB POS="POST">s</SB>, and W<SB POS="POST">s</SB>; and second windings U<SB POS="POST">mn</SB>, V<SB POS="POST">mn</SB>, and W<SB POS="POST">mn</SB>whose one ends are connected to the first terminals U<SB POS="POST">m</SB>, V<SB POS="POST">m</SB>, and W<SB POS="POST">m</SB>and the other ends are connected to a neutral point N of the electric motor. <P>COPYRIGHT: (C)2013,JPO&INPIT |
