Abstract

The utility model relates to a multi-power energy-saving motor. The utility model is characterized in that the utility model is provided with a plurality of stator and rotor pairs, each stator of the stator and rotor pairs is orderly arranged and fixed on the same machine seat; each rotor shares the same rotating shaft; when a plurality of stator and rotor pairs with identical rotary speed are used, the quantity of the switching on stator and rotor pairs is different, and then, the output power is different; when a plurality of stator and rotor pairs with different rotary speed output are used, the switching on stator and rotor pairs is different, and then, the output rotary speed is different; the stator and rotor pairs working in different running states equally can be in the optimum working states. Because the defect that the rotary speed and the power output of the existing motor is single is overcome, the utility model has the advantages that the efficiency of the motor is enhanced, the noise is reduced, the power consumption is reduced, and the utility model can be used for an occasion demanding a different speed and a multifunctional outputs and other occasions.

Description

The energy-saving multi-power motor

Technical field

The utility model relates to a kind of motor, particularly a kind of energy-saving electric machine with multiple power and the output of multiple rotating speed.

Background technology

It is right that existing motor has a rotor of being made up of stator and rotor, under "on" position, the electromagnetic field of stator and rotor interacts, drive rotor rotation, under rated power supply and load, the rotating speed of rotor is certain, the output of formation rated speed, change load and will change output speed and power, form certain output characteristic curve thus, on the difference of output characteristic curve, the energy conversion efficiency of motor, index such as noise and temperature rise is different, people often wish that rotor is to being in best running status, to raise the efficiency, reduce noise, but rated power that single rotor is right and rotating speed generally all are single, can not satisfy different burden requirements, even regularly at load one, because much bigger when the ratio of the power consumption when starting normally moves, single rotor is to also can not all being in optimal operational condition when starting and normally move, it is low to have produced electric efficiency thus, defectives such as noise is big, some motors are for satisfying the requirement of many speed outputs, a rotor on the coil of different rotating speeds has been installed, can satisfy the requirement of multiple rotating speed output like this, but that this motor does not still overcome efficient is low, the defective that noise is big.

The utility model content

For overcoming the above-mentioned defective of existing motor, the utility model provides a kind of energy-saving multi-power motor, and this motor can be exported multiple power and multiple rotating speed, and rotor is to being in optimum Working all the time, the efficient height, and noise is low, and energy-saving effect is obvious.

The technical scheme that the utility model solves the problems of the technologies described above is: it is right that motor is provided with a plurality of rotors, each rotor has same rotating shaft, each rotor also can have different output speeds or output characteristic curve to having identical output speed or output characteristic curve.

Because it is right to be provided with a plurality of rotors in the motor that the utility model provides, when adopt the identical rotor of rotating speed output to the time, the rotor of energising work is to the quantity difference, the power of output is just different, the rotor of selecting varying number under different power outputs just can make each rotor to all being in optimum Working to work; When adopt the different rotor of rotating speed output to the time, different rotors is to the different rotating speed of energising work time output, and the rotor in the work has improved efficiency of motor thus to being in optimum Working equally, reduce noise, reduced invalid energy consumption.

Description of drawings

Fig. 1 is a cross-sectional view of the present utility model.

Embodiment

As shown in Figure 1, it is right that the energy-saving multi-power motor that the utility model provides is provided with a plurality of rotors, each stator 1 sequence arrangement of each rotor centering also is fixed on the same support 7, each rotor 2 total same rotating shaft 9, the stator 1 of same rotor centering and the fit system of rotor 2 can adopt prior art and other possible technology of any suitable.

Described rotor is to being that to have a rotor of identical output speed or output characteristic curve right, and the rotor of varying number just can be exported different power to energising work like this.

Described rotor is to also being that to have a rotor of different output speeds or output characteristic curve right, and different like this rotors just can be exported different rotating speeds to energising work.

When described rotor when having different rotating speeds, the rotor under the same rotating speed under different output speeds, also can be realized different power outputs like this to being several.

Other parts of motor can adopt prior art or other possible designs of any suitable, generally, support 7 two ends can connect front end housing 10 and rear end cap 3 respectively, rotating shaft 9 connects with the bearing on front end housing 10 and the rear end cap 38,6, rotating shaft 9 front ends lean out from front end housing 10, are used to connect load, and the rear end leans out from rear end cap 3, the fan blade 4 that connects the cooling that is used to ventilate also is connected with on the rear end cap 3 fan blade 4 is covered on wherein fan housing 5.

It is right that embodiment shown in Figure 1 is provided with 3 rotors altogether, and according to the output requirement, rotor is to can also being that 2,4,5 or other are arbitrarily greater than 1 quantity.

Power output under the situation of rated power supply input that each rotor is right and rotating speed are mainly determined by the structure and the fit system of its stator, rotor, the right design of the rotor of different output power and rotating speed belongs to known technology, has multiple technologies scheme and method for designing to select.

For guaranteeing to of the control of each rotor to work, can also the supporting control device that is provided with, this control device can be arranged on the motor, also can with the motor body portion from, or be arranged to the control cubicle form, this control device can adopt electric elements control, also can adopt electronic circuit control, can also adopt the control of microcomputer or other control technologys, have multiple prior art scheme and method for designing available, how this control device is realized not constituting restriction of the present utility model.
