摘要： A motor rotor has a resin-impregnated thread layer formed by winding a thread of a reinforced fiber material around a permanent magnet layer with a gap between an outer peripheral surface of the thread layer and an inner peripheral surface of a cylindrical body, and impregnating the thread layer with a curable resin. A subsequent thread layer is formed by leading a continuous thread into an annular passage through thread passing recesses, winding the continuous thread around a bottom portion of the passage, and impregnating the subsequent thread layer with a curable resin. A curable resin is injected into the gap between the outer peripheral surfaces of the thread layer and the subsequent thread layer and the inner peripheral surface of the cylindrical body through resin injection passages and/or the thread passing recesses before heating and curing.

摘要： A motor with an electromagnetic brake is provided that is capable of sufficiently reducing influence of leakage magnetic flux on a magnetic sensor. A second ball bearing that rotatably supports a shaft at a position in the vicinity of a non-load-side end portion is configured to be ferromagnetic. An inner circumferential surface of a bearing stopper member that faces an outer circumferential surface of the shaft is disposed in proximity to the outer circumferential surface of the shaft. The bearing stopper member, which is ferromagnetic, is fixed to the second bearing holder in order to prevent the second ball bearing from getting out of a bearing fitting portion. A magnetic shield member is fixed to a portion of the shaft between the bearing stopper member and a magnetic sensor. The magnetic shield member guides leakage magnetic flux, which has been generated by an electromagnetic coil and leaked through the shaft, from the shaft to the bearing stopper member, thereby reducing influence of the leakage magnetic flux on the magnetic sensor.

摘要： The present invention provides a permanent magnet rotary motor in which cogging torque can be reduced without largely reducing the torque. When an angle formed between two virtual lines respectively connecting a center of a rotary shaft and both ends of a first type connecting portion 21A is defined as a first angle θ1 and an angle formed between two virtual lines connecting the center of the rotary shaft and both ends of a second type connecting portion 21B is defined as a second angle θ2, the relationship between the first angle θ1 and the second angle θ2 is θ1>θ2. A through-hole H1 is formed in the first type connecting portion 21A, which extends from a center position of the first type connecting portion 21A as viewed in an axial direction of the rotary shaft toward both sides in the axial direction. A through-hole H2 is formed in the second type connecting portion 21B, which extends from a center position of the second type connecting portion 21B as viewed in the axial direction toward both sides in the axial direction. The length, in a circumferential direction, of the through-hole H2 formed in the first type connecting portion 21A is longer than the length, in the circumferential direction, of the through-hole H2 formed in the second type connecting portion 21B. The length, in the axial direction, of the through-hole H1 formed in the first type connecting portion 21A is shorter than a length, in the axial direction, of the through-hole H2 formed in the second type connecting portion 21B.

摘要： A projecting portion 23h is integrally provided at a first connecting portion 23e of a bobbin 23. The projecting portion 23h has a triangular cross-section taken in an orthogonal direction orthogonal to a laminating direction of the steel plates 21 and parallel to magnetic steel plates 21. The section of the projecting portion is geometrically similar in shape to a cross-section of a fitting recessed portion 7a taken in the orthogonal direction. The cross-section of the projecting portion 23h is substantially the same in size as or slightly smaller than the cross-section of the fitting recessed portion 7a. With this arrangement, when one ends of six magnetic columns 13 of a magnetic pole constituent member 9 are brought into engagement with six fitting recessed portions 7a, projecting portions 23h passes through the fitting recessed portions 7a and come out of the fitting recessed portions 7a.

摘要： The present invention provides a stator for motors in which a space volume occupied by the winding wire of an excitation winding section can be increased, thereby allowing magnetic flux to readily flow through the yoke. On an inner peripheral surface portion of the yoke 7, a pair of flat-surface portions 7b are respectively formed in the circumferential direction on either sides of six fitted recesses 7a so that the flat-surface portions are continuous with the inner surfaces of the fitted recesses 7a. The pair of flat-surface portions 7b are located on the same virtual plane and have a side of an identical dimension that extends in the circumferential direction. The inner surface of the fitted recess 7a is constituted by a pair of inclined flat surfaces 7c respectively continuous with the pair of flat-surface portions 7b. The first flange portion 23b of the bobbin 23, which is in contact with the inner peripheral surface of the yoke 7, includes a flat plate-like body 23d and a pair of ribs 23e. With the excitation winding section 5 being mounted onto the stator core 3, the pair of ribs 23e are fitted into a pair of spaces 19 formed between the yoke 7 and the magnetic pole constituent member 9.

A pair of end surfaces of each of permanent magnets used for a rotor are substantially parallel to a virtual plane that extends in the radial direction of a rotor core while passing through the centers of a stator core and an arc surface. Then, the length of the arc surface in the peripheral direction of a rotor core and inclinations of inclined surfaces are so determined that a pole arc ratio Ψ1 of the arc surface and a pole arc ratio Ψ2 of a magnetic pole surface in each permanent magnet satisfy the relation of P/2N≦Ψ2−Ψ1≦1.38×P/2N.
