摘要： A mounting member 72 is formed which is pushed by a base plate 3 on the side from which a rotation shaft of the motor main body projects, that is to say, on the side on which the counter weight is mounted. A mounting member 81 is provided which is pushed by the base plate on the bracket 80 mounted on the other face opposite to that from which the rotation shaft of the motor main body projects. A supply terminal 90 having a spring characteristic and which is mounted on the bracket and a terminal 31 which supplies electricity are pressed together. A peaked section 71 is formed in the flexible holder mounted on the outer periphery of the motor main body so that the supply terminal is tightly held against the supply terminal.

摘要： A compact motor capable of being reflow-soldered, which can solve a problem of thermal demagnetization of a magnet with a simple structure, has magnets in a housing. At least a part of a surface to which the magnet is attached is separated by an acrylic adhesive sheet and heat resistant resin from metal members, such as a bracket and shaft forming part of the housing. The shaft is stainless steel having a low heat conductivity or an additional cover is used for the shaft to withstand reflow-soldering.

摘要： A DC brushless vibration motor is disclosed to comprise of a stator, a rotor, a drive circuit and a casing. The stator has an upper magnetic pole piece, a lower magnetic pole piece and a stator field winding. The stator field winding is contained inside a ring-shaped space formed by the upper and lower magnetic pole pieces. The internal rotor has a center of mass offset from the center axis of rotation and comprises a ring magnet and an eccentric weight. The eccentric weight has a structural configuration of a ring body, and the ring magnet is securely fixed to the external peripheral surface of the eccentric weight. The drive circuit has a drive integrated circuit for controlling the rotation of the rotor by receiving an externally-supplied electric power. The casing securely encloses the stator and rotor while maintaining an air gap therebetween for generating mechanical vibration when the rotor is propelled to rotate by the stator.

摘要： A vibration-generating device having a weight that is formed semicircular in section and has a recess near an insertion hole of a shaft. The weight, after being inserted onto the shaft, is supported in an inclined position by a support member. A pressing member applies a pressure to the recess. Preferably, the pressure is offset from the rotational axis of the shaft.

摘要： A vibration generating device having a weight which is formed semicircular in section and provided with a recess in the vicinity of an insertion hole of a shaft. The weight, after insertion on the shaft, is supported in an inclined position on a support block. Then, a tapered pressing member is moved downwardly to apply the pressure to the recess. In this case, the direction of pressure application of the pressing member is deviated from the axis of the shaft.

摘要： A flat-shaped vibration motor is described. The vibration motor has a base plate at its bottom. A cover is mounted on the base plate so as to define a space for installing elements therein. A shaft is vertically and rotatably mounted between the center of the base plate and the center of the cover. A lower PCB is mounted on the upper surface of the base plate. A magnet is positioned outside the lower PCB and has poles of 2n (n: a positive integer). An upper plate is fitted around the shaft and unbalanced in weight. A commutator is positioned on the central lower portion of the upper PCB and consists of multiple segments. A pair of brushes are mounted between the lower PCB and the commutator with their lower ends respectively and electrically connected to the lower PCB and their upper ends in contact with the commutator, an interval angle between the brushes being greater than an electric angle of Π/2 and less than an electric angle of 3Π/2. A coil unit consists of multiple elemental armature coils, the armature coils being connected to each other into the coil unit at a neutral point and being orderly activated, and each having an electric phase difference increasing by Π/2 in the order of activation.
