Description
The utility model relates to design of electrical motor and manufacturing, and it is a kind of simple in structure more clearly to say so, the improvement of the permanent magnetic DC motor of not only exportable rectilinear motion but also exportable gyration.
Traditional permanent magnetic DC motor is complex structure mostly, is made of support, stator, armature, motor shaft, commutator and brush etc.Its coil windings is intricate, and armature, commutator are also complicated.Complex structure must cause the reduction of processing technology complexity, manufacturing cost raising and reliability, makes the parts rapid wear perishable, and maintenance is also difficult.Traditional permanent magnetic DC motor stator is fixed, the rotor rotation, and output shaft can only be exported gyration.As want linear movement output, can only add transmission mechanism in addition.In addition, realize quite difficulty of infinitely variable speeds, its volume is generally also bigger.
The purpose of this utility model is to overcome above-mentioned shortcoming and defect, and a kind of both exportable rectilinear motion is provided, and exportable again gyration is very convenient; Simple in structure, technology is simple, and low cost of manufacture is not fragile, easy to maintenance, the continuously adjustable permanent magnetic DC motor of power output and rotating speed.
In order to achieve the above object, the utility model by support, be fixed on stator on the support, be installed in armature in the support, be installed in the output shaft on the armature and the commutator that is installed on the support is constituted.Parts are made of permanent magnet one of in stator and the armature, and corresponding another parts then are made of electromagnet.Electromagnet is made of bobbin and the conductive coil on bobbin.Conductive coil links to each other with the two poles of the earth of commutator, and output shaft is installed on the reciprocating armature.
Said stator and armature are formed one of situation by following four kinds: one. and stator and armature are made up of a permanent magnet and an electromagnet respectively.When the conductive coil of electromagnet (armature) was connected direct current, the two ends of electromagnet produced magnetic pole N, S.Opposite as electromagnet with the polarity that permanent magnet (stator) faces magnetic pole mutually, just electromagnet moves rapidly to permanent magnet under magnetomotive effect.When galvanic polarity reversing, electromagnet just moves rapidly away from permanent magnet under magnetomotive effect.The reciprocating motion of electromagnet drives also reciprocating motion outputting power of output shaft.Two. stator and armature are made up of an electromagnet and a permanent magnet respectively.Its operation principle is the same.Three. stator by about two permanent magnets constitute, armature is made of an electromagnet, but about the internal magnetic pole polarity of two permanent magnets should be identical, the permanent magnet on right side has is convenient to the hole that output shaft passes.When the conductive coil of electromagnet (armature) is connected direct current, the two ends of electromagnet produce magnetic pole N, S. electromagnet about under the double action of two permanent magnets (stator) rapidly to a lateral movement.When galvanic polarity reversing, just motion round about rapidly under magnetomotive effect of electromagnet.And so forth, just drive output shaft and exported power.Four. stator by about two electromagnet constitute, armature is made of permanent magnet, but about the internal magnetic pole polarity of two electromagnet should be identical, the electromagnet on right side has is convenient to the hole that output shaft passes.Its operation principle is with three.Commutator adopts the reversing switch circuit.
The end of output shaft is with holes, and output shaft is installed on the bent axle with the hole, and crankshaft installed constitutes the toggle that a reciprocating motion with armature changes the output that rotatablely moves of bent axle on support.So, the both exportable rectilinear motion power of the utility model, the also exportable power that rotatablely moves.
Regulate the exciting current of conductive coil, make it by little to increasing continuously the also increase continuously thereupon of electromagnetic force that armature is suffered greatly.Simultaneously, power output and rotating speed also increase thereupon continuously.Therefore, power output of the present utility model and rotating speed are all adjustable continuously, have realized step-less adjustment.
Task of the present utility model comes to this and finishes.
The utility model provides a kind of both exportable rectilinear motion, exportable again rotatablely moving, and flexible, simple in structure, technology is simple, low cost of manufacture, rapid wear bosom, the also simple permanent magnetic DC motor of maintenance.Under same power output, its compact conformation, volume is little, and is in light weight, and it is low to consume energy, and power is big, and it can be widely used in the electromechanical equipment manufacturing.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further explanation.
