Background technology
At present, hollow-cup motor is widely used on mobile phone vibrating motor, electronic toy motor, medicine equipment motor and electric toothbrush, Mature Audiences.But due to conventional drag cup motor, magnetic gap in the motor indoor design is large, magnetic circuit is long, thereby cause the moment of torsion of motor output less, and the limited space promoted, the output performance of this motor of occasion that therefore at some, has high torque to require can not reach instructions for use.
China Patent Publication No. CN2706946, open day is on June 29th, 2005, name is called in the scheme of " a kind of hollow cup vibration motor " and discloses a kind of hollow cup vibration motor, it has cylindrical housing, an end at shell is provided with by brush, base, the brush combination that terminal forms, characteristics are, it is provided with by shell, be fixed on the central shaft at shell center, be fixed on the stator that the permanent magnetic iron on central shaft forms, by centre frame, be fixed on the coil of centre frame one end, be fixed on the commutator of the centre frame other end, be fixed on bearing holder (housing, cover) and the bearing at centre frame center, be fixed on the rotor of the eccentric wheel composition of coil outside, central shaft is plugged in bearing, commutator is connected with brush.Weak point is, this drag cup motor, and the magnetic gap of its indoor design is large, magnetic circuit is long, thereby causes the moment of torsion of motor output less.
The utility model content
The utility model is that the magnetic gap in order to solve existing drag cup motor indoor design is large, magnetic circuit is long, thereby cause the less deficiency of moment of torsion of motor output, provide a kind of firmness good, moment stability is high, the moment of hollow-cup motor can be improved, a kind of high moment of torsion drag cup motor in the starting reaction time of hollow-cup motor can be shortened.
To achieve these goals, the utility model is by the following technical solutions:
A kind of high moment of torsion drag cup motor, comprise: the drag cup motor body, described drag cup motor body comprises drag cup and is located at the interior magnet steel in drag cup, also comprise that cross section is the outer steel of annular, and drag cup is arranged in the endoporus of outer steel, the N utmost point of outer steel and the S utmost point of interior magnet steel are arranged on the same end of drag cup.This programme is in order to improve the moment of hollow-cup motor, increase again by a ring outer steel on the basis of magnet steel in original monocycle, like this, in area of space, the magnetic direction of outer steel and the magnetic direction of interior magnet steel are on all four, make the magnetic induction of the drag cup motor of this programme will be twice left and right than the magnetic induction of existing drag cup motor.So, from long-range navigation magnetic force formula, the coil of this programme drag cup motor will be subject to being twice than current drag cup motor the moment of left and right in the process of cutting magnetic induction, thereby has improved moment of torsion.Not only can improve the density in magnetic field like this, can also shorten magnetic gap and field circuit, therefore can significantly improve the moment of hollow-cup motor, can greatly shorten the starting reaction time of hollow-cup motor.
As preferably, the lateral wall of described outer steel is fixed on the casing of described drag cup motor body.Firmness is good, and moment stability is high, is swift in response.
As preferably, the length of described outer steel and described interior magnet steel equal in length.Moment stability is high, is swift in response.
As preferably, the clearance distance of the madial wall of described outer steel and the lateral wall of described drag cup is less than 2 millimeters.This Stability Analysis of Structures is reliable, and moment stability is high.
The utility model can reach following effect:
This programme is simple in structure, and firmness is good, and moment stability is high, be swift in response, improve the magnetic density of hollow-cup motor, and shorten magnetic gap and field circuit, and significantly improved the moment of hollow-cup motor, greatly shortened the starting reaction time of hollow-cup motor.
