Abstract
The utility model discloses a kind of magnetite device for micro motor, comprise stator, and be located at the ferro-gum on stator inner wall; Described ferro-gum is strip, comprises the first doping region of rectangle, nonpolar district, the second doping region successively, and connects the bonding pad of three; First doping region is identical with the second doping region width, is greater than the width in nonpolar district, and bonding pad is the region of the width gradual change between doping region and nonpolar district; Ferro-gum is curled into cylindrical shape and is located at stator inner wall, and second doping region at two ends links together, relative with the first doping region; Be provided with V v notch v in the first doping region and the second edge, doping region, be provided with projection at nonpolar area edge.The beneficial effects of the utility model are, firmly can be connected with stator, save material, and can improve the cogging torque of motor.
Description
Technical field
the utility model relates to a kind of magnetite device for micro motor.
Background technology
in micro motor, stator needs arrange magnetite device to drive rotor turns, existing magnet, firm not with the connection of stator, and also material consumption is serious, and effect is also good not.
Utility model content
the purpose of this utility model is, overcomes the deficiencies in the prior art, provides a kind of magnetite device for micro motor.
for realizing this technical purpose, scheme of the present utility model is: a kind of magnetite device for micro motor, comprises stator, and be located at the ferro-gum on stator inner wall; Described ferro-gum is strip, comprises the first doping region of rectangle, nonpolar district, the second doping region successively, and connects the bonding pad of three; First doping region is identical with the second doping region width, is greater than the width in nonpolar district, and bonding pad is the region of the width gradual change between doping region and nonpolar district; Ferro-gum is curled into cylindrical shape and is located at stator inner wall, and second doping region at two ends links together, relative with the first doping region; Be provided with V-notch in the first doping region and the second edge, doping region, be provided with projection at nonpolar area edge.
the beneficial effects of the utility model are, firmly can be connected with stator, save material, and can improve the cogging torque of motor.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model;
fig. 2 is the structural representation of the utility model ferro-gum.
Embodiment
below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
as shown in Figure 1 and Figure 2, a kind of magnetite device for micro motor, comprises stator 1, and is located at the ferro-gum 2 on stator inner wall; Described ferro-gum is strip, comprises the first doping region 21 of rectangle, polarity 23 district of nonpolar district 22, second successively, and connects the bonding pad 24 of three; First doping region is identical with the second doping region width, is greater than the width in nonpolar district, and bonding pad is the region of the width gradual change between doping region and nonpolar district; Ferro-gum is curled into cylindrical shape and is located at stator inner wall, and second doping region at two ends links together, relative with the first doping region; Be provided with V-notch 25 in the first doping region and the second edge, doping region, be provided with projection 26 at nonpolar area edge.The setting of breach and projection, can improve the cogging torque of motor.The structural design of ferro-gum, is conducive on the flat thin magnet of a monoblock rectangle, do not waste material and makes maximum ferro-gums.
the above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection range that all should be included in technical solutions of the utility model.
