Abstract
The utility model discloses a rotor tangential structure for a permanent magnet synchronous motor. The rotor tangential structure is mainly characterized in that an iron core at one end of a permanent magnet groove, which is close to a winding, is punched to form a tooth. With the adoption of the rotor tangential structure provided by the utility model, not only can the problem of rotor radial flux leakage be solved, but also the mechanical strength of a rotor sheet is ensured.
Description
Technical field
The utility model relates to a kind of motor rotor structure, particularly be a kind of permanent-magnet synchronous motor rotor cutting orientation structure.
Background technology
At present, the rotor of permanent magnet synchronous motor is embedded with permanent magnet, is used for improving the efficient and the power factor of motor.The closure of permanent magnet magnetic circuit is divided into two parts, and a part is through rotor core formation closed magnetic circuit, i.e. the magnetic circuit of leakage field, and this is necessary under certain conditions.Another part is for forming closed magnetic circuit through stator core, and is many more like the magnetic line of force through stator core, just means that the utilance of permanent magnet is high more.Conventional permanent-magnet synchronous motor rotor is because the width of leakage field groove is big more, and leakage field is bigger, thereby has wasted permanent magnet material.And the leakage field well width is more little, and the mechanical strength at this position is more weak again in the punching, when rotor runs up for a long time, influences the running of rotor thereby the punching at this position can be ruptured by the effect of centrifugal force and electromagnetic force.
Summary of the invention
The purpose of the utility model is to provide a kind of radially leakage field little, the permanent-magnet synchronous motor rotor that mechanical strength is big to the problem that exists in the prior art.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
Comprise the punching that constitutes rotor; Said punching is provided with six permanent magnet trough; Form magnet isolation tank between said permanent magnet trough and the rotating shaft; Said permanent magnet trough is provided with an iron core by the tooth that washes away and form near an end of winding, forms the leakage field groove between said tooth and the winding, can reach the reasonable requirement of pole embrace.
According to the technical scheme of the utility model, on oblique permanent magnet trough, wash away a tooth, make the leakage field gap of this rotor reduce, thereby rotor core part leakage field is reduced, and then improved the effective rate of utilization of magnetic pole.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
EmbodimentA kind of permanent-magnet synchronous motor rotor cutting orientation structure; Comprise the punching 1 that constitutes rotor; Said punching 1 is provided with six permanent magnet trough 3; Form magnet isolation tank 5 between said permanent magnet trough 3 and the rotating shaft, said permanent magnet trough 3 is provided with an iron core by the tooth that washes away and form 31 near an end of winding 2, forms leakage field groove 4 between said tooth 31 and the winding 2.
In a word, the above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
