Abstract
The utility model discloses a direct driving type permanent magnetic alternating current numerical control motor without a brush which is directly connected with a machine head and is used for an industrial sewingmachine. A belt wheel is changed as the direct driving type that a motor rotating shaft and a principal axis of the machine head are linked directly. The utility model consists of two parts of an electromotor body and a numerical control timing device, comprises a stator assembly, a rotator assembly, a front end cover, a back end cover, a wind impeller, an output shaft and a coupling bolt and is characterized in that a rotator shaft is the output shaft which is a hollow tubular shaft cover which is directly mounted outside the principal axis of the sewingmachine head to be fixedly connected, so as to form the direct driving state. After the industrial sewingmachine and in particular a high-speed flat sewingmachine is matched with the product, the direct driving of 0 to 5000 circles per minute can be realized, and a programme can be set in advance, which can actually realize the numerical control. The stepless timing ensures no influence of inertia when the machine is stopped, which saves sewing threads; at the same time, because the motor is connected with the sewingmachine head directly, the structure is simple, and the appearance is nice; the utility model has little noise and low energy consumption and is the ideal matched motor of the new generation of the industrial sewingmachine.
Description
Technical field
The utility model relates to the manufacturing technology field of miniature motor, specifically refers to a kind of industrial sewing machine direct drive permanent magnetic alternating-current brushless numerical-control motor.
Background technology
At present, be used for the drive motors of industrial sewing machine, ac synchronous motor, variable-frequency motor arranged and the permanent magnet AC brushless motor that occurs in recent years etc., but the kind of drive of they and head all is belt transmission usually.This kind of drive no doubt has its superiority, can suitably regulate as belt pulley and the spacing between the head belt pulley and the tightness of belt etc. of motor; Sometimes have only the needlework of three or five pins also can stir belt pulley by hand and carry out work etc.But drive disk assembly is many after all for it, and mechanism's relative complex also will be wasted some sewing threads greatly because of the inertia of belt pulley sometimes.At these defectives, the someone proposes the mode that drives with directly, but because the speed change problem does not have fine solution always, so also there is not directly supporting drive motors of main shaft that a kind of and worker stitch machine till settled the present.
The utility model content
Technical problem to be solved in the utility model is: overcome the deficiency of the motor driven mode that existing industrial sewing machine uses, replace belt transmission with directly driving, make the handpiece structure of industrial sewing machine compact more, succinctly, use convenient.
The technical scheme of the utility model technical solution problem is: make belt pulley into direct-drive type that machine shaft and head spindle directly link.The utility model is made up of motor body and numerical control speed regulator two parts, and described motor body is made up of field frame assembly, rotor assembly, front end housing, rear end cap, fan blade, output shaft, shaft link bolt.Described front end housing, rear end cap connect into open motor housing with trip bolt, between front and rear cover clamping by being embedded the field frame assembly that winding constitutes; Being provided with in the middle of field frame assembly can be with respect to its axial rotor rotated assembly.
Described rotor assembly is that output shaft is formed by connecting by the rotor and the armature spindle of permanent magnetic material, described armature spindle is the tubular sleeve of hollow, directly being enclosed within the worker stitches outside the main shaft of machine head, the fixed cover that links to each other with armature spindle is provided with location hole, make armature spindle and head spindle positioning and fixing with the dog screw screw-in, thereby form direct driving condition.
Described shaft link bolt passes behind axis hole in the middle of the fan blade and the armature spindle center to screw with the default internal thread in the outer end of head spindle and is connected.
The winding lead-out wire of described field frame assembly coil is connected with plug, and plug inserts in the socket of numerical control speed regulator.
Described numerical control speed regulator is a box body, and its shell is provided with socket and speed governing knob, and inside is provided with chip and electronic circuit board.
Behind industrial sewing machine, especially high speed parallel sewing machine adapted the utility model, can realize the direct driving of 0-5000 commentaries on classics/min, and can preestablish working procedure, realize truly digital control.It can realize stepless speed regulation, and sewing the end of a thread is saved in noninertia influence during parking, simultaneously because of directly linking together with sewing machine head, thereby simple for structure, elegant in appearance, and noise is little, energy consumption is low, is the ideal matching motor of industrial sewing machine of new generation.
