摘要： PROBLEM TO BE SOLVED: To provide a slip-out preventing means, which prevents a rotor part from slip-out in a normal state and enables attachment/detachment of the rotor part easily, when necessary. SOLUTION: A motor 1 has a rotary shaft 41, a rotor part 4, a bearing part 23, a stator part 2 and a slip-out preventing means. The slip-out preventing means is composed of a retaining part (annular protruding part) 451 and a slip-out preventive part 81, which is provided on the stator part 2 and can be retained with the retaining part 451. The slip-out preventive part 81 maintains the retaining state with the retaining part 451 or the retainable state with the retaining part 451 and exhibits a slip-out preventive function within the predetermined limit of an unmating force applied in the longitudinal direction of the rotary shaft 41. When the construction of the motor 1 with the slip-out preventing means such as this is employed, even if an optical disc put on a turntable 42 is removed from the turntable 42, for instance, the slip-out of the rotor part 4 can be avoided through the function of the slip-out preventing means.

摘要： PROBLEM TO BE SOLVED: To provide a motor provided with a removal preventive means which usually prevents a rotor part from being removed and which can attach and remove the rotor part simply as required. SOLUTION: The motor 1 is provided with a removal preventive means consisting of a shaft groove (a coupling and stopping part) 412 which is formed on a shaft 41 and of a removal preventive member 81 which is installed at a stator part 2 and which can be coupled to, and stopped by, the shaft groove 412. The removal preventive member 81 maintains a state which is coupled to, or can be coupled to, the shaft groove 412 within the limit of a prescribed removal force acting in the length direction of the shaft 41, and it displays a removal preventive function. By the constitution of the motor 1 comprising the removal preventive means, it is possible to prevent a rotor part 4 from being removed by means of the action of the removal preventive means even when, e.g., an optical disk placed on a turntable 42 is separated and removed from the turntable 42.

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of an adhesion failure by preventing an adhesive that adheres a stator coil and a stator yoke from leaking out of a center hole, in a face-to-face type brushless motor. SOLUTION: A vertical cylinder 15 is arranged at the center of the bottom of this face-to-face type brushless motor holder 11. The adhesive A is injected on the stator yoke 13 on the bottom, and the stator coil 17 and the stator yoke 13 are adhered by placing a stator coil board 16 on a board receiving part 14 at the upper end of the face-to-face type brushless motor holder. By the arrangement of the cylinder 15, the adhesive A is prevented from leaking out of the center hole 18 of the stator yoke, and the adhesion failure can be prevented. Furthermore, since the cylinder 15 supports the center of the stator coil board 16, the warp of the stator coil board is prevented, thus generating an effect that stabilizes motor performance.

摘要： PROBLEM TO BE SOLVED: To provide a Hall element soldered to a substrate by a solder reflow method, wherein the Hall element is prevented from being buckled due to a compression stress of the substrate.
SOLUTION: A circular hole 5 is formed at the center of four lands 4 for soldering the Hall element of a glass epoxy substrate 3. Since, when the substrate is heated in a solder reflow process, a hole portion operates as an escape, the pitch change of the lands is reduced and a pitch difference relative to an electrode terminal 2 of the Hall element 1 having a small coefficient of thermal expansion is reduced. Further, as a constant as the spring of the substrate is lowered, when the substrate shrinks after soldering, compression stress applied to the Hall element is reduced, and a degree of buckling or a degree of deformation of the Hall element is reduced.

摘要： PROBLEM TO BE SOLVED: To improve the strength of fixing a rotor yoke to a shaft in the direction of rotation without increasing the height of a motor.
SOLUTION: A D-shaped mounting protrusion 32 of a shaft 30 includes a flat portion 36. The flat portion 36 is formed using a cutter cut to an end face 31 thereof, and is extended into a slit 37 beyond the end face 31 thereof. A D-shaped mounting hole 22 in the rotor yoke 20 is formed by punching out a top plate portion 21 from the back face side. An edge of the mounting hole 22 in the back face of the top plate portion 21 is a burr-free face 26. The mounting hole 22 in the rotor yoke 20 is fit onto the mounting protrusion 32 of the shaft 30 without being influenced by burrs, and the flat portion 36 is abutted against the entire thickness of the top plate portion 21.
