In the vibrating motor of the present invention, the coil in two groups of coils of rotor winding is by the connected mode connection of the single wave winding of DC motor.During work, two groups of coils of rotor winding are all switched on and are produced torque.Two groups of coils of rotor winding are by its structure, and one group is distribution coil, and another group is a concentrating coil.In described distribution coil group, the radial section that adjacent two coils are adjacent is overlapping, and through being shaped at last, the excircle section and the medial segment of this distribution coil group outwards protrude, and form the semi-round ring shape groove.Do not have overlapping between adjacent two coils in the described concentrating coil group, be floor plan.
Flat permanent magnetic DC vibrating motor of the present invention has following outstanding characteristics and significant advantage:
(1) vibrating motor rotor winding of the present invention is divided into distribution coil group and concentrating coil group, and the single wave winding connected mode of DC motor is adopted in the connection of two groups of coils.Two groups of coils are all switched on and are produced torque during work, thereby have improved the space availability ratio of winding and the efficient of motor.
(2) the own centre-of gravity shift of motor rotor does not need other eccentric component and realizes the vibrating function of motor, makes designs simplification.
(3) flat commutator is inlaid in the rotor winding inner side end, does not increase the axial width of rotor.
(4) permanent magnetism magnetic pole of stator stretches in the semi-round ring shape groove of rotor end-face, has reduced the axial air-gap of permanent magnetism magnetic pole, has improved the efficient of motor, and can save the energy content of battery.
(5) rotor shaft, winding coil and flat commutator become one by plastic forming technology, and enough mechanical strengths are arranged.Stator cage two ends iron chains dress self-lubricating bearing had both made designs simplification in addition, and was also the same with plastic pressuring process, was convenient to produce in batches.
