Abstract
The stator is formed by overlapped and fixed multiple silicon steel sheets. There is a central hole in the stator for rotor to reside. There are multiple parallel-arranged winding grooves on the wall of the central hole. The groove possesses a narrow opening leading to the central hole. The special point is that the grooves on the stator are tilted. After the winding is buried into the grooves and is electrified, the produced stator magnetic lines distributes evenly. The magnetic lines produced by the adjacent windings are continuous. The invention raises the working efficiency of motor.
Description
(1) technical field:
A kind of stator structure of AC motor of the present invention refers to a kind of magnetic line of force tool continuity that makes between stator slot to be produced especially, improves the stator structure of AC motor of moyor.
(2) background technology:
See also shown in Fig. 1～3, known alternating current motor stator 30 is piled up by plural silicon steel sheet 31 to form, middle tool one medium pore 32 holds installing for rotor 40, the hole wall of medium pore 32 equidistantly is provided with a plurality of axial wire casings 33, make in the wire casing 33 and can place coil, the notch 330 of wire casing 33 tools one slot shape communicates with medium pore 32.Behind coil electricity, the coil in each wire casing 33 just produces the magnetic line of force to drive rotor 40 rotations.The wire casing 35 of known stator and notch 330 and notch 330 cause the magnetic line of force intensity of adjacent two wire casings 33 centres the most weak because of being axial setting, and the magnetic line of force has the inequality of distribution and the continuity of not having lacks, and influences moyor, haves much room for improvement
(3) summary of the invention:
Main purpose of the present invention is providing a kind of magnetic line of force that makes to distribute on average and the tool continuity, to promote the stator structure of AC motor of motor operations efficient.
Principal character of the present invention be: the wire casing of stator is oblique setting, make coil insert the magnetic line of force that the energising back is produced in the wire casing, it is average to have the distribution of the stator magnet line of force, and the magnetic line of force tool continuity that adjacent windings produced, and can promote the effect of motor operations efficient.
A kind of stator structure of AC motor of the present invention, its stator is piled up and fixedly connected forming in addition by plural silicon steel sheet, and the centre has a medium pore, stretches into placement for rotor, the medium pore hole wall has the wire casing that plural number is arranged in parallel, and wire casing communicates with medium pore with the notch of slot shape; It is characterized in that: this wire casing is oblique setting.
Wherein, the groove that the set plural number of rotor peripheries is arranged in parallel is also done oblique setting, and groove is opposite with the incline direction of wire casing.
Wherein, the notch of stator slot and wire casing are done to tilt in the same way.
A kind of stator structure of AC motor of the present invention, its advantage is: it can make the magnetic line of force distribute on average and the tool continuity, the high efficiency of motor, rotor rotation is smooth and easy.

(5) embodiment:
Please visit shown in Fig. 4～7, a kind of stator structure of AC motor of the present invention, its stator 10 are piled up by plural silicon steel sheet 11 to form, and middle tool one medium pore 12 is inserted for a rotor 20.The plural wire casing 13 of the evenly equidistant distribution of medium pore 12 hole wall tools is inserted for coil.Each wire casing 13 communicates with medium pore 12 with the notch 130 of one narrow mouthful of shape.Principal character be:
Because wire casing 13 is oblique setting, coil is inserted in the wire casing 13, the magnetic line of force tool continuity that 13 of adjacent wire casings are produced, except that can promoting motor operations efficient, rotor 20 is also had a smoothness on rotating.
