摘要: A single-phase PWM converter system in accordance with the present invention employs a sample-and-hold circuit which samples and holds a direct current in the state wherein one of two-phase gate signals of a positive or negative side arm is ON and the other phase is OFF, determines the sign of an output of the sample-and-hold circuit according to the two-phase gate condition, detects a phase current at the input side of the converter, and controls a voltage at the input side of the converter so that the detected current value agrees with a power supply current command. Further, a three-phase PWM converter system in accordance with the present invention detects the effective current and the ineffective current of the power supply current from the direct current, and based on the values, controls the PWM converter so that the sine wave power supply current whose power supply power factor is 1 is provided.

摘要: A drive apparatus overcomes the problems of ensuring accurate mounting of a plurality of armature coils relative to a plurality of magnetic pole position detectors, limitations concerning the location for mounting, and the extension of primary-side length. The drive apparatus comprises a primary side including an arrangement of a plurality of armatures each having a core made of a magnetic material with coil windings. It also comprises a secondary side including a permanent magnet movably supported relative to the armatures via a gap. A magnetic pole position detector is disposed between adjacent armatures.

摘要: Disclosed herewith a compact linear motor provided with a plurality of magnetic pole teeth and used to increase the thrust force by canceling a magnetic attractive force working between the primary member and the secondary member. The linear motor comprises a primary member and a secondary member. The primary member includes cores formed with a magnetic material and an electromagnetic coil wound on the cores while the secondary member supported so as to be capable of moving relatively with respect to the primary member with a gap therebetween. In the linear motor, the coil that is wound commonly on the cores is also disposed between adjacent magnetic pole teeth.
