Description
Technical field
The utility model relates to a kind of permanent magnet machine rotor, particularly a kind of hybrid vehicle rotor of permanent-magnetic power generator.
Background technology
The rotor of conventional magneto adopts the colligation of no latitude glass tape, magnet steel to tighten with screw more or the rotor cylindrical adds the method for collar, when these technology more complicated are taken a lot of work, and be subjected to the restriction of the inter-air space, generator is when running up, rotor magnetic steel flies to escape and cracked situation happens occasionally, thereby whole aircraft reliability is poor.Because above rotor structure adopts is magnetic conduction mode radially, and electric efficiency is lower.
Summary of the invention
The purpose of this utility model provides a kind of permanent magnet machine rotor of realizing the tangential poly-magnetic mode of efficient and high reliability.
A kind of tangential poly-magnetic permanent magnet machine rotor, it comprises rotating shaft, magnetic conductive core, rubidium iron boron magnet, key, magnetic conductive core adopts the silicon steel rotor punching to be overrided to form vertically, the order that the rubidium iron boron magnet is separated by by N, S the two poles of the earth is built in the silicon steel rotor punching and laminates vertically in the rectangular channel of formation, and magnetic conductive core is connected with rotating shaft by key.
Its stator of the utility model adopts skewed slot, positive chorded winding, can effectively reduce the resistive torque of generator.The permanent magnet motor structure of this tangential poly-magnetic p-m rotor is simple, is convenient to install, and the specific power height, the generating efficiency height, in light weight, resistive torque is little, improves the reliability of complete machine greatly.
