摘要： One end of a shaft is fixed to a first portion of a housing. An eccentric rotor is located in the housing rotatably on the shaft. The other end of the shaft is fitted into a concave portion on a second portion of the housing, so the rotor may be assembled in the housing in a simple manner and radial movement of the shaft can be prevented without enlarging the fixing portion of the shaft. Even if the diameter of the shaft is small, the shaft can withstand an impact resulting from dropping of the motor.

摘要： A vibrator motor has a generally sector-shaped eccentric armature rotor that has a nonmagnetic body including core parts, around which armature coils are individually wound. The core parts are disposed at an even pitch angle, but within a 180.degree. angular range, about the rotational axis of the rotor. A rotor body of one embodiment consists of a first part and a second part that includes the core parts and the first part is made of a synthetic resin and the second part is made of a synthetic resin or a nonmagnetic but electrically-conductive metal. A rotor of an additional embodiment has a single-piece body of a synthetic resin that integrally has the core parts.

摘要： A small dc vibrator motor for use in a wireless alerting device includes a housing, a non-rotatable shaft fixed to the housing, a cylindrical magnet fixedly mounted on the shaft, and a rotor which is rotatably mounted on the shaft. The rotor includes a cylindrical coreless winding assembly between the magnet and the housing, and eccentric bearings, or combinations of concentric bearings and eccentric weights, on both ends of the winding assembly. The eccentric bearings, or the combinations of concentric bearings and eccentric weights, cause vibrations when the rotor rotates.

摘要： A flat coreless vibrator motor includes a casing for housing the motor, a shaft rotatably supported by the casing, a rotor mounted on the shaft and being generally in the shape of a sector, the shaft being disposed at the center of a circle, along which a generally arc-shaped outer periphery of the sector generally extends. At least three armature coils are provided on the rotor and are angularly arranged in such a manner that these armature coils do not overlap each other. A magnet is mounted on the casing so as to generate a magnetic flux. A commutator and brushes cooperate with each other to supply electric power to the armature coils. Since the rotor is eccentric, vibrations are produced during the rotation of the rotor.
