ABSTRACT:
A motor which uses a permanent magnet is provided in which output thrust is improved by increasing a magnetic saturation limit and preventing reduction in magnetic flux and generation of heat is reduced by inhibiting generation of an eddy current in a magnetic pole. An N magnetic pole is formed such that its width increases as the distance from a stator increases on a side of an N pole magnetic yoke and an S magnetic pole is formed such that its width increases as the distance from the stator increases on a side of an S pole magnetic yoke. With this structure, a saturation limit of magnetic flux at an entrance of yoke which is a connection section between the N magnetic pole and the N pole magnetic yoke is increased and motor thrust is improved.
