The permanent magnet can reduce the moment of magnetic resistance.
Description
Technical field
The utility model relates to the motor technology field, is specifically related to a kind of magneto.
Background technology
Permanent magnet synchronous motor mainly is to be made of stator, rotor, end cap, stator and rotor adopt electromagnetic induction, stator is fixedlyed connected with end cap with two ends of rotor, stator comprises support and the stator core of band winding, the stator core of band winding is pressed on the support through forcing press, be provided with rotating shaft, rotor core, aluminium ring and vertical bar shaped permanent magnet in the rotor, rotating shaft is pressed on the rotor through forcing press, and the vertical bar shaped permanent magnet is embedded in the inboard of rotor.Permanent magnet has high remanent magnetism, when inlaying, take suitably every the magnetic measure, the mutual magnetic action to each other of reduction permanent magnet is convenient to install 3 two ends and is adopted and fixed every the aluminium sheet of magnetic, prevent moving axially of permanent magnet, the deficiency of this structure: because permanent magnet is a vertical bar shaped, the utilance of permanent magnet is low, and magnetic leakage factor is big, a little less than the anti-degaussing ability, the ability of pulling in of motor is low, the overload magnification of reluctance torque and motor is low.Though existing technology has solved the problems referred to above.But for stator, stator is with what silicon steel sheet was made change riveting or be welded of groove punching to be arranged.Because the existence of line embedding groove causes the motor gas-gap magnetic conductance inhomogeneous, so magnetic resistance moment exists all the time.Magnetic resistance moment is different along with the power of shape, size and the performance of magnet steel, and is also different along with the size of iron core notch.Also along with iron core skewed slot and different whether, certainly also with the size of each several part unshakable in one's determination and different, also there is very big relation the while with the size of air gap.How to reduce magnetic resistance moment, become the current need of magneto problem to be solved.
Summary of the invention
At above-mentioned technical problem, the purpose of this utility model provides a kind of magneto that can reduce magnetic resistance moment.
The technical scheme that realizes above-mentioned purpose is as follows:
Magneto, comprise rotor, end cap, stator, rotor comprises rotating shaft, rotor core, aluminium ring and permanent magnet, described permanent magnet is made up of a plurality of arc-shaped permanent magnet piecemeals, the rotor core inboard is provided with the deep-slotted chip breaker that matches with the arc-shaped permanent magnet piecemeal, arc-shaped permanent magnet piecemeal correspondence is embedded in the deep-slotted chip breaker and by the aluminium ring and fixes, stator comprises stator core and winding, winding is arranged in the line embedding groove that is provided with in the stator core, be provided with the magnetic element that is used for magnetic conduction in the described line embedding groove, this magnetic element is arranged at the notch place of described line embedding groove.
Be provided with chock in the described line embedding groove, this chock is between magnetic element and winding.
The width of described magnetic element and the width of described line embedding groove about equally, the length of described magnetic element and the equal in length of line embedding groove.
Adopted such scheme, promptly be provided with the magnetic element that is used for magnetic conduction in line embedding groove, this magnetic element is arranged at the notch place of described line embedding groove, like this air gap is remedied, thereby has reduced magnetic resistance moment, and motor properties is improved.By chock is set, can increases the stability of magnetic element in line embedding groove, and help further reducing air gap.
