Abstract
The utility model relates to a stepper motor, and especially relates to a stepper motor having a housing which is formed by overall stamping. The stepper motor includes the housing, a spool stand disposed at the front end inside of the housing, a rotor which penetrates through spool stand, and a Hall sensor which is disposed at the rear end inside of the housing of the stepper motor and is used for counting the rotation turns of the rotor. The stepper motor is characterized in that the housing is formed by overall stamping and is in the shape of a cylinder; the Hall sensor is built inside the motor; and the conventional separate design of the motor body and signal parts is replaced. A rear cover is disposed at the tail end of the housing and is sealed and connected with the housing. Four leads of a coil on the spool stand are lead out from the tail end of the housing. The stepper motor is characterized by good sealing performance, long service life, low production cost and small size.
Description
Technical field
The utility model relates to a kind of stepping motor, and particularly a kind of shell adopts whole stamping forming stepping motor.
Background technology
Stepping motor is that first stepping motor part is controlled in the open loop that changes electric impulse signal into angular displacement or displacement of the lines.The in the situation that of non-overload, frequency and the umber of pulse of pulse signal only depended in the rotating speed of motor, the position stopping, and be not subject to the impact of load variations, when step actuator receives a pulse signal, it rotates a fixing angle with regard to Driving Stepping Motor by the direction of setting, be called " step angle ", its rotation is that the angle of fixing is moved step by step.Can carry out pilot angle displacement by control impuls number, thereby reach the object of accurate location; Can control by control impuls frequency speed and the acceleration of electric machine rotation, thereby reach the object of speed governing simultaneously.So the wide range of stepping motor application, in the communications field, can adjust by stepping motor the angle of antenna for base station, thereby can control signal of communication very easily.
For the control of stepping motor, not only require stepping motor can take the angle rotation of discrete magnitude, also require the angle of rotation to monitor, so transducer need to be set at the tail end of stepping motor in order to monitor the anglec of rotation of stepping motor.This transducer is only just used in special field, and common stepping motor is not possess transducer, this transducer all can adopt directly the shell of the shell of transducer and stepping motor is welded together when manufacturing for this reason, poor sealing due to welding, cause these stepping motors of working out of doors to damage because leak, affect the life-span of stepping motor.
Utility model content
The purpose of this utility model is exactly in order to solve the problem of the stepping motor poor sealing of said structure in prior art, the stepping motor that the utility model provides a kind of novel shell to adopt whole punching press to form.
Concrete technical scheme of the present utility model is as follows:
The utility model provides a kind of stepping motor, this stepping motor comprises shell, is arranged at the drum stand of shell Inner Front End, through the rotor in drum stand, in described stepping motor shell, rear end is provided with the Hall element that rotates the number of turns for calculating rotor, it is characterized in that, described shell is for adopting the whole cylindrical shape being stamped to form.
Described shell end is provided with a bonnet, and described bonnet is connected with body seal.
Four lead-in wires of the coil on described drum stand are drawn from the end of shell.
Described Hall element comprise one be positioned at drum stand end be pressed into pin, fixed cover be located at epitrochanterian lifting magnet, with the pcb board that lifting magnet is oppositely arranged, described pcb board is fixedly connected with four lead-in wires of coil on drum stand by pin hole.Described lifting magnet is circular, is oppositely arranged two magnet on this circular magnet dish.
Compared to prior art, the shell of the utility model stepping motor adopts integrated punch forming, without welding, has avoided the seepy question that causes because the weld seam of welding is poorly sealed, long service life, and adopt integrated punching moulding production cost cheaper.
In addition, the lead-in wire of stepping motor of the present utility model is drawn from end, compared to stepping motor in prior art, from side, draw, can reduce the diameter of stepping motor, on equipment in same space, adopt the diameter of stepping motor of the present utility model larger, the outputting torsion of generation is also larger.
accompanying drawing explanation
Fig. 1 is the stereo unfolding schematic diagram of the utility model stepping motor;
Fig. 2 is the stereogram of the utility model stepping motor.
embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the utility model, is not used for limiting the utility model.
Embodiment
The utility model provides a kind of stepping motor, this stepping motor comprises a columnar shell 11, this columnar shell 11 adopts integrated being stamped to form, in the inside of shell 11, be provided with rotor 12, drum stand 13, lifting magnet 14 and pcb board 15, described rotor 12 is located in described drum stand 13, the front end 121 of described rotor 12 stretches out from the front end of shell 11, described drum stand 13 is positioned at shell 11 Inner Front Ends, the end 131 of drum stand 13 is provided with and is pressed into pin 132, on pin 132, be connected with pcb board 15 being pressed into, on described drum stand 13, four lead-in wires of coil are connected with four pin holes 151 on pcb board 15 respectively, be provided with lifting magnet 14 being pressed between pin 132 and pcb board 15, described lifting magnet fixed cover is located at the end (not shown) of described rotor 12, in the rear end of described shell 11, be connected with a bonnet 16, described bonnet 16 is tightly connected with shell 11, the end of described bonnet is provided with line hole 161, four power lines are drawn from described line hole 161.
The shell of the utility model stepping motor adopts integrated punch forming, without welding, avoided the seepy question that causes because the weld seam of welding is poorly sealed, long service life, and adopt integrated punching moulding production cost cheaper.Hall element is built in motor internal; Substitute traditional motor body and signal part separate design.
In addition, the lead-in wire of stepping motor of the present utility model is drawn from end, compared to stepping motor in prior art, from side, draws, can reduce the diameter of stepping motor, on equipment in same space, adopt the diameter of stepping motor of the present utility model larger, the torsion of generation is also larger.
It should be noted that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
