Abstract
The utility model discloses a permanent magnet and electromagnet combined energy-saving motor which comprises a housing, electromagnet salient poles and a rotor. There are six electromagnet salient poles and all of the electromagnet salient poles are arranged on the inner circumference of the housing. The energy-saving motor also comprises four permanent magnets which are uniformly disposed on the outer circumference of the rotor. According to the innovative motor's energy-saving structure provided by the utility model, it is constantly and proportionally energy-saving with the revolving speed of the motor by the use of the permanent magnets. Under light load of the motor, incoming current of electromagnet is reduced, and with the assistance of the permanent magnets, dual efficient energy-saving effect is reached.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to the energy-saving motor that a kind of permanent magnet combines with electromagnet.
Background technology
Existing energy-saving electric machine mainly is the control device that feeds back to input current according to the information that motor load changes, and reduces the input of electric current when the motor underloading, to reach energy-conservation purpose.But the effect that adopts this method to reach is unsatisfactory, and affects motor speed.
Summary of the invention
The energy-saving motor of the purpose of this utility model with regard to being to provide a kind of permanent magnet to combine with electromagnet in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises shell, electromagnet salient pole and rotor, it is characterized in that: described electromagnet salient pole is six, evenly is arranged on the inner periphery of described housing, and described energy-saving motor also comprises permanent magnet, described permanent magnet is four, evenly is arranged on the excircle of described rotor.
Particularly, the minimum clearance between described permanent magnet and the described electromagnet salient pole is 0.1-0.5cm.
The utility model adopts the stator of motor identical with existing stator, but relevant technical parameter changes to some extent.Difference is: one of characteristics are to be provided with many pieces of permanent magnets on the rotor.The magnetic pole that two of characteristics produce when being the energising of electromagnet salient pole is identical with the magnetic pole near permanent magnet, only produces repulsion.Three of characteristics are when being in always on the line plugged when electromagnet salient pole center line, near permanent magnet center line and the armature spindle center of circle, the adjoining not electromagnet salient pole of energising of epitrochanterian another half permanent magnet and direction of advance also just enters the suction scope, the acting of help electromagnet reaches energy-efficient effect according to this fact.
The beneficial effects of the utility model are:
The energy saving motor structure that a kind of innovation is provided of the present utility model, it can utilize permanent magnet along with the invariablenes turning speed ground of motor, energy-conservation pari passu.When the motor underloading, reduce the input current of electromagnet, add that the power-assisted of permanent magnet reaches the energy-conservation effect of Dual high-efficiency.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Among the figure: 1-shell, 2-electromagnet salient pole, 3-permanent magnet, 4-rotor.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in drawings: the utility model comprises shell 1, electromagnet salient pole 3 and rotor 4, electromagnet salient pole 2 is six, evenly is arranged on the inner periphery of housing 1, and described energy-saving motor also comprises permanent magnet 3, permanent magnet 3 is four, evenly is arranged on the excircle of rotor 4.Minimum clearance between permanent magnet 3 and the electromagnet salient pole 2 is 0.1-0.5cm.
As shown in drawings: six protruding 2 utmost points of electromagnet are respectively A1, A2, A3, A4, A5 and A6, and the permanent magnet 3 that is fixed on the rotor 4 is respectively B1, B2, B3 and B4.
As shown in drawings: A1 and B1, produce repulsion promotion B1 and B3 when A4 and B3 centring line plugged and rotate clockwise, meanwhile A6 and B4, A3 and B2 just enter the suction scope.Because A6 and A3 do not switch on, be by permanent magnet B2 and B4 acting, so Here it is core technology of the present utility model place, energy-efficient essential place.A1 and A4 outage when A6 and B4, A3 and B2 centring line, A3 and A6 energising produce repulsion promotion B2 and B4 rotates clockwise, and meanwhile B1 attracts A2, and B3 attracts A5, helps the electromagnet drive rotor to rotate clockwise.
