Description
Technical field
The utility model relates to a kind of motor, is specifically related to a kind of industrial sewing machine servomotor.
Background technology
Existing industrial sewing machine servomotor comprises stators and rotators two parts, and its rotor generally all comprises rotating shaft and is coated at the bearing of rotating shaft, viewed from version, mainly there is following defect:
1, the use of bearing generally needs bearings mounted support and position, support and generally need front and rear cover bearing chamber, the precision of bearing chamber processing is relatively high, and processing cost is relatively high, leave position and also need certain space, the relative increase of motor volume can be caused;
2, the conventional mounting arrangements of motor and sewing machine adds a shaft coupling at motor-shaft extending place, this mounting means is higher to motor-shaft extending requirement of beating, also require higher to sewing machine shell motor installed surface perpendicularity, and the cooperation of shaft coupling also needs relatively high machining accuracy, the particularly control of both axialities; In three, the bad sewing machine moment that all can make of control increases, and noise during operation increases, and the performance affecting machine shortens the useful life of sewing machine.
Summary of the invention
The purpose of this utility model is to provide a kind of industrial sewing machine servomotor reducing difficulty of processing, reduce costs, improve motor performance.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of industrial sewing machine servomotor, is characterized in that: comprise stator module and be arranged on the rotor assembly on head of sewing machine main shaft, described stator module comprises motor casing, motor stator, electric motor end cap, bearing, grating seat, rubber ring, lenticular lenses, collar cover, detector and dust cover, described motor casing and motor stator fix and be set on rotor assembly with its formation matched in clearance, one end of motor casing is fixed on sewing machine casing, its other end is provided with electric motor end cap, described bearing is arranged in electric motor end cap, grating seat is connected with end cap by bearing, lenticular lenses is fixed on grating seat end by collar cover, detector is connected with electric motor end cap by the bearing pin be positioned on electric motor end cap, dust cover is arranged on motor casing.
Rubber ring is provided with between described lenticular lenses and grating seat.
Compared with prior art, it has following advantage:
1, the utility model is easy for installation, and location is reliable: do not need shaft coupling between motor and head of sewing machine, can control coordinating between motor with sewing machine well, operationally noise is less to make sewing machine, extends the useful life of sewing machine;
2, the utility model compact conformation, the small and exquisite cost of outward appearance is cheaper: compare conventional motor, and this electric machine structure is simple, volume is little, low cost of manufacture, is conducive to reducing noise, improves the reliability of work, also makes sewing machine complete machine cost decline.
