Abstract
The utility model discloses a stepping motor which includes a motor shaft, a housing, a rotor, a stator, and a stator coil. The rotor includes a magnet body. The stator coil is wound on the stator. The stepping motor is characterized in that the central part of the magnet body is provided with a shaft hole, and the motor shaft is arranged in the shaft hole. The stepping motor integrates an original magnet body with a shaft sleeve, thus effectively reducing the cost and optimizing the production technology.
Description
Technical field
The utility model relates to a kind of stepping motor, the stepping motor that specifically a kind of production technology is simple, cost is low.
Background technology
At present; Stepping motor is widely used in all trades and professions; Existing stepping motor mainly is made up of arbor, shell, rotor, stator, permanent magnet and stator coil, and rotor, stator, permanent magnet and stator coil are positioned at shell, and permanent magnet is arranged on the rotor; Rotor is installed on the motor shaft, and stator coil is wrapped on the stator.The magnetite body of existing stepping motor is installed on the motor shaft through axle sleeve, has the shortcoming of cost height, complex manufacturing.In addition, original stepping motor is restricted in some spaces and partly moment is required still can't satisfy performance requirement through changing other parts on the higher product, on product applications, is restricted.
Summary of the invention
The purpose of the utility model provides the stepping motor that a kind of production technology is simple, cost is low.
The purpose of the utility model realizes through following technical scheme.
A kind of stepping motor comprises motor shaft, shell, rotor, stator and stator coil, and rotor comprises the magnetite body, and stator coil is wrapped on the stator, it is characterized in that: the center of said magnetite body is provided with axis hole, and motor shaft is located in the axis hole.
The utility model compared with prior art has the following advantages.
It is integrated that the said stepping motor of the utility model makes original magnetite body and axle sleeve into the magnetite body, effectively reduces cost and optimization production technology.
Description of drawings
Fig. 1 is the structural representation of the utility model stepping motor rotor;
Fig. 2 is the structural representation of the utility model stepping motor flute profile;
Fig. 3 is the structural representation of the utility model stepping motor coil holder.
Embodiment
Below in conjunction with accompanying drawing the utility model stepping motor is described in further detail.
Like Fig. 1, Fig. 2 and shown in Figure 3; The main motor shaft of the described stepping motor of the utility model, shell, rotor, stator and stator coil are formed, and rotor comprises the magnetite body, and stator coil is wrapped on the stator; The center of magnetite body 1 is provided with axis hole, and motor shaft 2 is located in the axis hole.It is integrated to make original magnetite body and axle sleeve into magnetic magnetic, effectively reduces cost and optimization production technology.Utmost point tooth 3 areas are strengthened the utility model lengthening lengthening motor body length and coil holder 4 winding spaces strengthen; Thereby motor-field intensity is enhanced; Motor torsion can be increased more than 20% on existing like product, and it is not enough to substitute the application of original similar motor on some product.
