Description
Technical field
The utility model relates to the compatible motor of a kind of DC permanent magnet, belongs to technical field of motors.
Background technology
At present, existing motor can only meet that rotating speed is high, moment of torsion is little or rotating speed is low, moment of torsion is large.Above phenomenon is that the characteristic curve due to motor itself determines, for example existing permanent-magnet brushless DC electric machine characteristic is that electric current increases, and motor speed is accelerated, when motor reaches certain rotating speed, even if add large electric current, motor speed does not have too large variation (motor magnetic saturation) yet again.And moment of torsion will decline when rotating speed improves.Just there is the defect that existing motor speed is high, moment of torsion is little or rotating speed is low, moment of torsion is large in this.
Summary of the invention
The purpose of this utility model is to provide a kind of DC permanent magnet compatible motor, and it changes original structure, has solved the deficiency of motor in the past; Increased Motor torque, had the advantages that rotating speed is high, moment of torsion large, save space and the energy, made motor in the situation that rotating speed is high, moment of torsion is still very large.
The technical solution of the utility model is achieved in that the compatible motor of a kind of DC permanent magnet, motor left end cap, left motor for preventing protecting cover bolt, motor right end cap, right motor for preventing protecting cover bolt, motor casing, consist of, left motor for preventing protecting cover, right motor for preventing protecting cover and left oil sealing, right oil sealing are equipped with respectively in its two ends at motor casing; Left motor for preventing protecting cover by left motor for preventing protecting cover be bolted on motor left end cap, right motor for preventing protecting cover is bolted on motor right end cap by right motor for preventing protecting cover; It is characterized in that: motor shaft runs through motor internal by left bearing and right bearing, the inside of the compatible motor of DC permanent magnet is comprised of stator coil, rotor permanent magnet, armature, left brush assembly, right brush assembly, Hall switch; Wherein on stator coil, being wound with coil is connected with right brush assembly with left brush assembly by brush wire, left brush assembly is fixed on motor left end cap by left brush assembly set bolt, right brush assembly is fixed on brush attachment panel by right brush assembly set bolt, on brush attachment panel with stablizing boss, in mating connection with motor right end cap, by right motor for preventing protecting cover, compress, armature is on rotor permanent magnet, with motor shaft coaxial rotation.
Good effect of the present utility model is to have solved the problem that requires motor high speed, high pulling torque in equipment in the past; Increase Motor torque, had the advantages that rotating speed is high, moment of torsion large, save space and the energy, by permanent-magnet brushless DC electric machine, combined to realize the effect of the high rotating speed of motor, high pulling torque with series DC machine; Make motor in the situation that rotating speed is high, moment of torsion is still very large.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described: as shown in Figure 1, 2, 3, the compatible motor of a kind of DC permanent magnet, motor left end cap 1, left motor for preventing protecting cover bolt 2, motor right end cap 14, right motor for preventing protecting cover bolt 16, motor casing 10, consist of, left motor for preventing protecting cover 3, right motor for preventing protecting cover 15 and left oil sealing 4, right oil sealing 20 are equipped with respectively in its two ends at motor casing 10; Left motor for preventing protecting cover 1 by left motor for preventing protecting cover bolt 2 be fixed on motor left end cap 1, right motor for preventing protecting cover 15 is fixed on motor right end cap 14 by right motor for preventing protecting cover bolt 16; It is characterized in that: motor shaft 5 runs through motor internal by left bearing 8 and right bearing 21, the inside of the compatible motor of DC permanent magnet is comprised of stator coil 11, rotor permanent magnet 12, armature 22, left brush assembly 6, right brush assembly 19, Hall switch 17; Wherein on stator coil, being wound with coil is connected with right brush assembly 19 with left brush assembly 6 by brush wire 9, left brush assembly 6 is fixed on motor left end cap 1 by left brush assembly set bolt 7, right brush assembly 19 is fixed on brush attachment panel 13 by right brush assembly set bolt 18, on brush attachment panel 13 with stablizing boss, in mating connection with motor right end cap, by right motor for preventing protecting cover, compress, armature 22 is on rotor permanent magnet, with motor shaft coaxial rotation.
During work when 25 energising of motor U line 23, motor V line 24, motor W line, the self-field that stator coil 11 produces magnetic field and rotor permanent magnet 12 interacts, armature spindle is rotated, when armature spindle forwards certain angle to, by Hall switch 17, control and make rotor continue high speed rotating (similar to permanent-magnet brushless DC electric machine operation principle).At the same time, armature 22 rotates with motor shaft 5, brush assembly work, thus strengthen magnetic field, finally improve the moment of torsion (similar to series DC machine operation principle) of motor.
Motor characteristic is that electric current increases, and motor speed is accelerated, and when motor reaches certain rotating speed, even if add large electric current, motor speed does not have too large variation (motor magnetic saturation) yet again.Rotating speed is high, and moment of torsion will decline, but the compatible motor of DC permanent magnet is when rotating speed improves, and brush assembly work strengthens motor-field on the basis in original magnetic field, and Motor torque is got a promotion, thereby has made up motor little phenomenon of moment of torsion when high rotating speed.
The compatible motor of DC permanent magnet is by permanent-magnet brushless DC electric machine, to combine to realize with series DC machine the effect of the high rotating speed of motor, high pulling torque.
