Abstract
A permanent magnet motor series connection rotor has long service life and high power generation benefit, a front claw pole and a rear claw pole are fixed at two ends of a middle claw pole through two permanent magnets, magnetism isolating rings are fixed on the excircles of the permanent magnets, the magnetism isolating rings function as preventing the permanent magnets from breaking and flying out, 1Cr18N9Ti material is adopted to make the steel shaft of the permanent magnet motor series connection rotor, the steel shaft using the material does not need reuse a magnetism isolating cover to conduct magnetism isolating, and thus the effective usage rate of the permanent magnets can be improved. The volume of a motor is reduced by using the permanent magnet series connection rotor, and the calorific value of the motor can be diminished.
Description
Technical field
The present invention relates to a kind of rotor of motor, especially a kind of magneto tandem rotor.
Background technology
At present, the structure of known permanent magnet machine rotor is by fore paw pole, permanent magnet, rear solid end pole, magnetic shield, magnetic partiting ring and motor shaft composition, this traditional rotor is all provided with magnetic shield, due to material and the dynamo steel axle tight fit of magnetic shield, magnetic shield is different with the coefficient of expansion of dynamo steel axle, when machine operation temperature is higher, the coefficient of expansion of magnetic shield is greater than the coefficient of expansion of steel axle, now magnetic shield will automatically disengage steel axle when running up, whole motor is caused to scrap, be exactly the useful space that can occupy permanent magnet after rotor uses magnetic shield in addition, the power benefit of permanent magnet is reduced.
Summary of the invention
In order to overcome the deficiency of more than existing magneto, the invention provides a kind of magneto tandem rotor, this rotor not only can increase the useful life of motor, can also increase the power benefit of motor.
The technical solution adopted for the present invention to solve the technical problems is: fore paw pole, median claw pole and rear solid end pole are connected as one by permanent magnet, and then carry out snap fit with steel axle.Fore paw pole is identical with the structure of rear solid end pole, the end face owing to placing permanent magnet is provided with at the two ends of median claw pole, the cylindrical of permanent magnet is provided with a magnetic partiting ring, first one piece of permanent magnet is fixed on an end face of median claw pole during installation, first piece of permanent magnet is installed regardless of N pole or S pole, then fore paw pole is installed on the permanent magnet of median claw pole, then another block permanent magnet is installed to the other end of median claw pole, it is correct for installing and producing past extrapolability side between the end face of median claw pole during second piece of permanent magnet and permanent magnet, then be fixed as one by permanent magnet after being alignd with the number of poles of fore paw pole in rear solid end pole, finally be pressed into motor shaft, the screwed hole for provided with fan is had at the two ends of pawl pole, front and back.What steel axle adopted is 1Cr18N9Ti material, and the steel axle employing this material carries out every magnetic with regard to not needing to re-use magnetic shield, and improves the availability of permanent magnet.By using this permanent magnetism tandem rotor to reduce the volume of motor, the caloric value of motor can be allowed to diminish.
The invention has the beneficial effects as follows, use this magneto tandem rotor not only can increase the useful life of motor, the power benefit of motor can also be increased.
