摘要： An electric motor has an armature rotatably accommodated inside a motor housing and a pair of magnets fixed to an inner surface of the motor housing so as to face the armature. The armature has an armature core 17 fixed to a rotating shaft 16, and ten slots S1 to S10 formed on the armature core accommodate coils. These slots S1 to S10 are of four types that are different in shape, thereby enhancing a lamination factor of each coil. Also, these slots S1 to S10 are formed so as to be tilted in a rotating direction with respect to an axial direction of the rotating shaft 16. Therefore, a magnetic imbalance caused by the slots S1 to S10 being formed in varying shapes is uniformized.

摘要： An electric motor comprises a stator and a rotor rotatably mounted confronting the stator. The rotor has a rotor core which comprises at least a first tooth, a second tooth and a third tooth which are adjacent. Each of the teeth comprises a rib section radially and outwardly extending from a core and a tooth section located at an outer end of the rib section. The angle between the first tooth and the second tooth is n degrees, wherein when the rotor core is rotated n degrees to move the first tooth towards the second tooth, the rotated second tooth does not coincide with the pre-rotated third tooth.

摘要： In order to provide a vibration motor which can make a starting force strong with maintaining saving electric power and increase a vibration force, in the vibration motor, a facing gap between a central salient pole and a pair of auxiliary salient poles are shifted and arranged around a rotating shaft with non-centrosymmetry and a facing gap between the central salient pole and the field magnet is formed narrower than facing magnets between the auxiliary salient poles and the field magnet. Further, an exciting force of the central salient pole is greater than that of the auxiliary salient poles and in starting, the same magnetic pole as the magnetic pole of the field magnet generates in a facing surface of the central salient pole and a repulsive force occurs so that the armature core is urged to rotate.

摘要： A small-sized motor includes a rotor, which, in turn, includes a shaft, a laminated core forming salient magnetic poles an odd number and mounted on the shaft, windings, each being wound around a plurality of salient magnetic poles, and a commutator mounted on the shaft. Each salient magnetic pole includes an arm portion and wing portions, which are integrated with ends of the arm portion and circumferentially extends symmetrically with respect to the arm portion. When core laminations of the laminated core each has a thickness u, the laminated core has a diameter D, and the wing portion has a thickness t as measured at its root in a radial direction, the thickness t falls within the range from 5.5% the core diameter D as an upper limit to the core-lamination thickness u as a lower limit. Thus, it becomes possible to solve a problem of a rotor having an odd number of poles in that vibration is likely to arise, to thereby suppress vibration, while maintaining a feature of the rotor that a large torque can be produced.
