摘要： A variable reluctance position sensor and a method for determining a position of a rotating body are provided. The variable reluctance position sensor includes a rotatable member configured to be operably coupled to the rotating body. The rotatable member (192) has a first non-magnetic body portion (212) and a plurality o magnets (194, 196, 198, 200) disposed equidistant from one another around an exterior region of the first non-magnetic body portion (212). The variable reluctance position sensor further includes a stator assembly (210) having a second non-magnetic body portion with an aperture extending therethrough for receiving the rotatable member therein. The stator assembly further includes a plurality of coils (230, 232, 234) and a plurality of coil brackets (214, 216, 218). Each coil of the pluralit of coils is attached to a respective coil bracket of the plurality of coil brackets. The plurality of coil brackets (214, 216, 218) is fixedly attached equidistant from one another to the second non-magnetic body portion. Rotation of the rotatable member induces the plurality of coils (230, 232, 234) to generate voltage signals indicative of position of the rotatable member.

摘要： The invention relates to a separately excited electric machine with a rotor (2) and a stator (1) and a device for detecting the rotational position of the rotor with respect to the stator. According to the invention, the position detection device is provided to determine the rotational position of the rotor by evaluating a marked signal which can be detected by a pole winding switch by means of rotational dependency on pole winding inductance. The invention provides the mutual position of the rotor and stator in one such electric machine without mounted sensors, whereby no interfering influence of the excited magnetic field inside the machine occurs.

摘要： Pour détecter la position angulaire du rotor (13) à aimant permanent d'un moteur sans balais, on connecte des moyens de mesure aux enroulements du stator de façon à former un circuit oscillant et l'on mesure les variations de la fréquence de résonance en fonction de la position du rotor. Afin d'augmenter ces variations, le rotor comporte autour de l'aimant (14) une structure amagnétique (26) qui présente des zones d'épaisseurs différentes ou de perméabilités différentes. Cette structure peut être formée par une douille métallique, par exemple en laiton, ayant des ouvertures ou évidements (44) qui peuvent être remplis d'une matière diélectrique.

摘要： In a brushless motor which includes a stator (26) and a rotor (1) rotatably supported inside the stator and wherein the rotor has a yoke (2) formed by laminating a large number of steel sheets (4), the yoke has an even number of magnetic poles (5) protruding outward, and a permanent magnet (3) for a field is inserted into each, or every other, magnetic poles, the permanent magnet rotor of the present invention has a structure in which the permanent magnet for the field is inserted into a slot (6) formed in the magnetic pole, and protuberances (9) striking the side surfaces of the permanent magnet for the field are disposed at the right and left portions of the slot. Further, in the present invention, in the brushless motor of this kind, engagement pawls (12) engaging with the permanent magnet for the field are so disposed as to protrude, reliefs (13) for absorbing a bend of the engagement pawl are formed in those of the steel sheets laminated to form the yoke which correspond to the engagement pawl. The steel sheets of the yoke are deviated on one or both ends sequentially in the rotating direction. A bridge width at both ends of the slot is set to be greater than the greater one of a width capable of being punched out and a width allowed from a mechanical strength due to a centrifugal force between the width capable of being punched out, a width allowed from the number of passing magnetic fluxes and the width allowed from the mechanical strength due to the centrifugal force. Further, at least one connecting portion of gap is provided to each magnetic pole so as to laminate the steel sheets. The bridge width at both end of the slot is set to be smaller than a width from the outside portion of the permanent magnet for the field to the outside edge of the magnetic pole.

摘要： The stator core 2A of stator 1A has slots 3A with closed inner ends 3a which are tapered to form prism-shaped chambers. The stator core 2A can thus be cooled by passing cooling gas through chambers 3a. This configuration also causes the magnetic flux from permanent magnets 6 of the rotor 5 to pass through retaining ring 8 and air gap 9 and then to pass the inner ends 3a of the slots of stator core 2A. This helps to prevent oscillation of magnetic flux density in the peripheral direction, reduces the eddy currents in retaining ring 8 which accompany this oscillation, and prevents temperature rise.

摘要： An electric motor, method of manufacturing and operating the motor is described. The motor comprises a stator (82) and rotor (74) made from an amorphous material thereby reducing grain boundaries and allowing smaller poles to be etched. The rotor (74) is spaced from the stator (82) by means of an air cushion as dictated by Bernoulli's principle. The rotor (74) is supported by means of a bearing assembly (70) centralized by means of a magnet that magnetically couples with an annular ring formed on the rotor.
