Description

Energy-saving motor

Technical field:

The utility model relates to the motor technology field, is a kind of energy-saving motor specifically.

Background technology:

Its rotor of existing magnetic motor generally is three utmost point windings, be that commutator and copper shoe are three, when work done is rotated, copper shoe contacts with brush and mostly is two most, and motor rotates always has a slice copper slide plate not have contact brush in the week, have only a winding work done, all the other two not works done of winding, the secondary winding is cutting magnetic line in rotate in magnetic field, and the induced current of generation does not transport out, the energy that can not get producing; The electromagnetic core of existing in addition its rotor of magnetic motor generally is three utmost points, and the attraction between permanent magnet and the electromagnetic core is cancelled each other, and does not make full use of the attraction of permanent magnet and iron, could rotate under the effect by electric power fully.

Summary of the invention:

The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of energy-saving motor is provided, and has mainly solved the problem that existing motor does not make full use of the attraction of permanent magnet and iron.

In order to achieve the above object, the utility model is achieved in that energy-saving motor, and it is made up of stator and rotor, and stator comprises stator casing 1, on the madial wall of stator casing 1, establish permanent magnet 2, establish end cap 3 at the one end, establish axis hole 4, establish brush 5 on the end cap 3 at the center of end cap 3, brush 5 is connected with copper conductor 6, establish end cap 13 at shell 1 other end, establish brush 14 on end cap 13, brush 14 is connected with copper conductor 15; Rotor comprises electromagnetic core 7 and rotating shaft 8, its special character is to establish on the electromagnetic core 7 coil 9, be the secondary winding, establish insulating barrier 10 in rotating shaft 8, establish commutator 11 and 12 respectively on insulating barrier 10, commutator 11 is connected with coil 9 respectively with 12, commutator 11 and 12 is respectively two copper slide plates of symmetry, each copper slide plate accounts for 1/4th of circumference, and commutator 11 becomes an angle of 90 degrees with 12 on the circumference of rotating shaft 8, and rotating shaft 8 is plugged in the axis hole 4

Energy-saving motor of the present utility model, its described permanent magnet 2 is the circular-arc of two symmetries.

Compared with the prior art energy-saving motor described in the utility model has following good effect: because two slide plates of the commutator of energy-saving motor of the present utility model respectively are 1/4th arcs of circumference, be half of commutator of original motor, promptly power consumption is half of original motor; Thereby under the attraction force acts of magnet and iron, not electricity consumption of half-turn when making rotor rotation simultaneously can be the electromagnetic induction of coil on the electromagnetic core and permanent magnet generation, and the electric current that cutting magnetic line produces transports out, and reaches better energy-saving effect.

Experimental results show that: when adopting the 3V power supply when energy-saving motor of the present utility model rotates, its out-put supply is about 0.8V, drive the small generator generating in rotor banding moving gear rotation and can produce voltage about the 1V electricity, and existing motor is when adopting the 3V power supply equally, can produce voltage about the 1.2V electricity by the same small generator of gear driven, hence one can see that, and energy-saving motor of the present utility model can be exported the voltage about 0.6V more, and power consumption only is former motor half.

The A-A cut-away view of Fig. 2---Fig. 1.

Embodiment:

In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and describe the utility model energy-saving motor in detail.

Embodiment 1, referring to Fig. 1,2, be processed into stator casing 1, fixed installation permanent magnet 2 on the madial wall of stator casing 1, permanent magnet 2 is the circular-arc of two symmetries, at stator casing 1 one ends end cap 3 is installed, offer axis hole 4 at the center of end cap 3, and brush 5 is installed on end cap 3, and brush 5 is connected with copper conductor 6, and copper conductor 6 is connected with the input power supply, at stator casing 1 other end end cap 13 is installed, brush 14 is installed on end cap 13, and brush 14 is connected with copper conductor 15, and copper conductor 15 is an out-put supply; Be processed into rotor electromagnetic core 7 and rotating shaft 8, on electromagnetic core 7, coil 9, be the secondary winding, fixed installation insulating barrier 10 in rotating shaft 8, fixedly mount commutator 11 and 12 on insulating barrier 10 respectively, commutator 11 is connected with coil 9 respectively with 12, and commutator 11 and 12 is respectively two copper slide plates of symmetry, commutator 11 becomes an angle of 90 degrees with 12 on the circumference of rotating shaft 8, at last rotating shaft 8 is plugged in the axis hole 4.

Energy-saving motor described in the utility model, its electromagnetic core are two utmost point windings, during work, when permanent magnet and iron core are attracted to the two poles of the earth closest approach, commutator 11 contacts with brush 5, energising this moment, outage automatically behind the rotation half-turn, commutator 12 contacts with brush 14, under the attraction force acts of permanent magnet and electromagnetic core, the rotor rotation half-turn, electromagnetic core arrives the two poles of the earth closest approach of permanent magnet, so circulation is rotated further motor.

Simultaneously, in the half-turn of rotor rotation, because the electromagnetic induction that electromagnetic core and permanent magnet produce, the electric current that cutting magnetic line produces also can contact with brush 14 by commutator 12, transports out by copper conductor 15 again after outage.
