Abstract
The utility model relates to a motor, in particular to a permanent magnetic DC stepless speed variable motor for an industrial sewer, which comprises a rotor, a permanent magnetic stator, a brush, an output shaft (3) and a casing (1). The utility model is characterized in that between a rotor shaft (2) and the output shaft (3), a gear reducer is arranged. The gear reducer is placed in a cavity (12) at the output end of the casing (1), and constitutes an integrated body with the cavity. The gear reducer on the permanent magnetic DC speed variable motor changes a prior brush DC speed variable motor from the outputting of high speed and small torque into low-speed high-torque outputting, meets the sewing for shoes, bags, back cushions for automobiles, canvas products, etc., and is of simple structure and low cost.
Description
Technical field
The utility model relates to a kind of motor, especially for the DC stepless time adjustment motor of industrial sewing machine.
Background technology
But the permanent magnet brush direct current machine has hard mechanical property bringing onto load starting, can directly drive the sewing machine starting operation with motor shaft when therefore being used for the industrial sewing machine equipment, and not as common asynchronous moter, turn round continuously by the driven by motor flying wheel, drive sewing machine by clutch by output shaft again, therefore on the very low equipment of this load factor of industrial sewing machine, use obvious energy conservation, used in a large number.In making industry, except that clothes with the flat seam machine, shoemaking, case and bag, Car Cushion, need on the sewing devices such as canvas work with the slow-speed of revolution, high pulling torque motor, and the DC buncher is relevant with the magnetic pole area because of output torque, as makes the low-speed big motor, volume and weight is very big, and cost is very high simultaneously; Asynchronous machine need be made 4 extremely above pole motor could realize low speed, needs to increase the flying wheel quality simultaneously because of speed is low and could guarantee starting torque, and same volume and weight is very big, and cost is very high.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, low rotation speed large torque DC buncher that cost is low for the deficiency that overcomes existing product.
To achieve these goals, the technical solution that the utility model adopted is as follows: low rotation speed large torque DC buncher comprises rotor, permanent-magnet stator, brush, output shaft and housing, be provided with gear reduction between armature spindle and output shaft, described gear reduction is arranged on and forms an integral body in the die cavity of housing output one side.
Further be provided with as the utility model, housing output one side is provided with boss, raised head face is provided with sagging die cavity and the end cap that matches, armature spindle penetrates and is provided with rotor bearing from cavity bottom and supports, armature spindle is provided with pinion, output shaft penetrates die cavity and is supported on end cap and cavity bottom respectively by bearing from end cap, and output shaft is provided with gear wheel and pinion constitutes reducing gear.
The beneficial effects of the utility model: the gear reduction on the DC buncher will have the output of brush dc speed-regulating motor by high rotating speed, little moment of torsion originally, be converted to low-speed big output, satisfied shoemaking, case and bag, Car Cushion, canvas work etc. and made requirement, and cost simple in structure is low.
The utility model is described in further detail below in conjunction with drawings and Examples.
