摘要： A method and a system for determining deterioration of permanent magnets of an electric apparatus to be inspected that facilitate determination without the need to remove the electric apparatus from a facility where it is installed. If the electric apparatus to be inspected is a three-phase linear motor, a current detector is used to acquire currents. A three-phase/two-phase conversion section converts the acquired currents into an α-axis current command and a β-axis current command. A locus of a current vector is computed based on the α-axis current command and the β-axis current command. A comparing and determining section compares the computed locus with a standard upper limit value stored in a storage means. If the number of times that the locus of the current vector exceeds the standard upper limit value exceeds a predetermined value, it is determined that the permanent magnets have been deteriorated.

摘要： A linear motor in which the shape of magnetic pole surfaces of pole teeth located at both ends of a plurality of pole teeth can be easily formed to be suitable for reducing cogging force. Each of magnetic pole surfaces 19a of pole teeth 15A located at both ends of a plurality of pole teeth 15 is constituted by an arc-shaped curved surface that is curved so that a gap from a stator 1 increases with increasing distance from other adjacent pole tooth 15B. Through holes 23A and 23B that extend in the laminating direction of electromagnetic steel plates 10 are formed in the vicinity of the magnetic pole surfaces 19a of the pole teeth 15A. Inside the through holes 23A and 23B, magnetic pieces, which are shorter than the thickness of the electromagnetic steel plates in their laminating direction, are arranged so as to leave spaces at both ends of the through holes 23A and 23B.
