摘要： PURPOSE: A magnetic encoder is provided to generate the magnetic flux of a sinusoidal wave shape simply that the transmission of waveform is little. CONSTITUTION: A magnetic encoder comprises permanent magnet rows(15,17), a magnetic piece row(9), and magnetic force detectors(19,21). The permanent magnet rows are formed of a plurality of permanent magnets which is aligned that magnetic poles of identical polarity are faced or the magnetic poles of different polarity are faced by interposing a non-magnetic material. The magnetic piece row includes a plurality of magnetic pieces aligned separately along the permanent magnetic rows. The magnetic force detectors detect leaked magnetic flux generated when the displacement of a relative position is generated between the permanent magnetic rows and the magnetic piece row. Pitches of the permanent magnets and pitches of the magnetic pieces are set to form a magnetic path that the magnetic flux generated by one of the permanent magnets of the permanent magnet rows when the displacement of the relative position between the permanent magnetic rows and the magnetic piece row is consecutively generated is returned to the permanent magnetic row via the permanent magnet next to the permanent magnet or one of the magnetic piece facing the non-magnetic material.

摘要： PURPOSE: A degradation determination method and an apparatus thereof are provided to determine the degradation of a permanent magnet by comparing with a standard upper limit stored in a storage device. CONSTITUTION: A three-phase linear motor acquires a current using a current detector(9).

The three-phase to two-phase converter calculates a trajectory of a current vector based on the α-axis reference current and the β-axis reference current. A comparison-determination part compares a result with a standard upper limit stored in a storage device. The comparison-determination part determines degradation generated in a permanent magnet(19).
