摘要： A turntable device includes a disc base on the circumference thereof, and the disc base has a hardness more than a given level. The surface of the disc base is roughened at a given level in order to prevent the disc from slipping and adhesion to the disc base. The disc base can compensate surface wobble caused by the disc base. A manufacturing method of the turntable device includes the steps of: a) dripping liquid resin mixed with fine particles on the circumference of the turntable; and b) hardening the resin to form the disc base. The turntable device is good for e.g. CD players, optical disc driving apparatuses.

摘要： A structure of a rotor used in a synchronous motor employing both of permanent magnets and a stator using concentrated windings is disclosed. Slits (13) provided in a section of a rotor laminated in a direction of a rotary shaft are shaped like an arc or a bow, and the shape protrudes toward an outside rim of rotor (12). Permanent magnets (14) are inserted into slits (13). This structure produces less magnetic salient poles than a conventional rotor, so that a magnetic flux density can be lowered, and an efficient motor with less loss is obtainable.

摘要： In a motor control apparatus, a current control section (1) controls the motor current by judging whether the current value detected by the current detecting unit (4, 7, 14) is of an overcurrent level exceeding an admissible value (Tmax) or a normal level which is equal to or smaller than the admissible value. When the current value detected by the current detecting unit is of an overcurrent level, the current control section restrains the current value to be supplied to the motor irrespective of the external motor torque or speed command, and when the current value detected by the current detecting unit becomes to be the normal level, the current value to be supplied to the motor is restored to an original non-restraint level.

摘要： A discrete rotor position estimation method for a synchronized reluctance motor is provided. A d.c.-link voltage Vdc and a phase current Iph are sensed. A flux-linkage λph of an active phase is calculated from the sensed d.c.-link voltage Vdc and the sensed phase current Iph. The calculated flux-linkage λph is compared with a reference flux-linkage λr. The reference flux-linkage λr corresponds to a reference angle θr which lies between angles corresponding to aligned rotor position and non-aligned rotor position in the synchronized reluctance motor. An estimated rotor position θcal is obtained only once when the calculated flux-linkage λph is greater than the reference flux-linkage λr.
