Abstract
The utility model discloses a double-magnet electric machine which comprises a stator, a shaft of the electric machine and rotors. The utility model is characterized in that the middle part of the stator is provided with a through hole in which the shaft of the electric machine is hung and arranged; both ends of the shaft of the electric machine forms an axial connection with an end cover of a casing; the rotors are respectively and symmetrically fixed on shaft of the electric machine of both sides of the stator; air gaps are axially separated among the stator and the stators. Due to the adoption of the proposal, the rotors are arranged at axial both sides of the stator and the rotors can rotate and work at both sides of the stator under the action of a rotating magnetic field. Thus the rotating magnetic field produced by a stator winding can be fully utilized. Simultaneously, the electric machine has the characteristics of smooth operation, low noise and high output power.
Description
The utility model relates to a kind of motor, more particularly relates to a kind of Double-magnet electric motor, belongs to a kind of improvement of motor.
Motor, normally constitute by fixing and rotating two essential parts, standing part is stator again, it is made up of shell, stator core and stator winding, stator core is by folded integrated cylindric being pressed in the shell of silicon steel sheet, the teeth groove that silicon steel sheet stamps out is evenly distributed on the iron core internal circular surfaces, and parallel with motor shaft, places stator winding in the teeth groove; Rotating part is rotor again, rotor is made up of motor shaft and the cylindrical rotor iron core and the rotor winding that are contained on the motor shaft, the motor shaft two end supports is on the bearing of shell two side ends lid, and the rotor core usefulness silicon steel sheet of jet-bedding builds up, and places the rotor winding in the groove.The rotor of motor places in the cylindrical chamber of cylindrical stator, decided and rotor between be separated with air gap.Behind stator winding electrifying, around stator, form rotating magnetic field, rotor is producing electric current under the effect of rotating magnetic field in the rotor winding, make rotor form the electromagnetic torque rotation.But, this motor can only one stator and rotor collapsible type join and work, and rotor can only utilize the rotating magnetic field of a side in the stator winding tube, motor stator can not effectively be utilized in the rotating magnetic field that periphery produces, cause the power output of motor low, noise reaches galloping greatly.
The purpose of this utility model provides a kind of Double-magnet electric motor, and it not only can make the rotating magnetic field at stator two ends be fully utilized, and motor power output height, noise is little and running steadily.
The purpose of this utility model is to realize like this, it includes shell, stator core, stator winding, motor shaft, rotor core and rotor winding, the middle part that it is characterized in that stator is provided with through hole, motor axle suspension inserts in that the end cap at its two ends and shell is coupling in the through hole at stator middle part, rotor is being fixed on the motor shaft in the stator both sides of symmetry respectively, axially is separated with air gap between stator and rotor.
Owing to adopted such scheme, rotor places the both sides of stator and the motor shaft that passes the stator center hole to fix, two rotors are worked under the rotating magnetic field effect of stator both sides respectively, the rotating magnetic field that makes stator winding produce like this is fully utilized, motor rotation is steady simultaneously, noise is little, the power output height can improve power 1.3-1.35 doubly.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a concrete structure cut-away section schematic diagram of the present utility model.
Fig. 2 is cuing open of another embodiment and structural map.
In Fig. 1-2, stator core 11 middle parts at stator are provided with copper siphunculus 8, silicon steel sheet strikes out rectangular sheet, the square silicon steel sheet of one group leader is vertical successively around the siphunculus 8 folded stator cores 11 that stick into annular with siphunculus 8 in the outside of siphunculus 8, on two side end faces of annular stator core 11, be milled with the teeth groove 6 that distributes symmetrically and evenly, stator winding 7 places teeth groove 6, after having the stator core 11 cards stator yoke 5 that upward non-magnet material is made of stator winding 7, be fixed on by hold-down screw 12 in the motor housing 1 of support upper end.Middle part at the rotor core 2 of rotor is provided with copper tubular clip 4, and silicon steel sheet strikes out rectangular sheet, and the square silicon steel sheet of a group leader sticks into annular around clip 4 is folded successively in that the outside of tubular clip 4 and clip 4 are vertical, makes rotor core 2.Outer surface at the rotor core 2 of annular is milled with equally distributed teeth groove 3, and the rotor winding of sliver formula places rotor teeth groove 3.Motor shaft 10 hangs in the pore of the siphunculus 8 that is inserted in stator, the two ends of motor shaft 10 are connected with end cap 9 bearings at motor housing 1 two ends, two rotors on the motor shaft that is installed in the stator both sides 10 of symmetry, are connected with motor shaft 10 keys respectively, are separated with the air gap of 0.4mm between rotor and stator.Or in the motor housing 1 of the upper end of support, install two stators side by side, and again three rotors are interted to be fixed on the motor shaft 10 respectively successively and is connected with motor shaft 10 keys, behind the air gap of rotor and stator interval 1mm stator is clipped in the middle successively.Or three stators and four rotors are joined and are worked.
During work, electrical power, at this moment stator winding 7 produces rotating magnetic fields, makes the rotor in two symmetries of stator 11 both sides produce the magnetomotive force rotor rotation under the effect of stator both sides rotating magnetic field.Be suitable for producing micromachine, middle and small motor, reach large-size machine, also can produce generator simultaneously with fork-like farm tool used in ancient China.
