Description
Technical field
The utility model relates to a kind of contactless suspension rotor, the contactless suspension rotor of particularly a kind of motor.
Background technology
At present, motor is widely used as the common apparatus of mechanical industry.Along with the development of modern mechanical ﹠ electrical technology, motor is had higher requirement.Motor can produce noise and heating in the process of running, this is that interior ring, outer shroud and the ball contact friction in the running of bearing causes.This structure not only produces noise and heat, and friction and wear can influence rotating speed of motor, efficient and useful life simultaneously.Because motor machining accuracy problem also can produce and beat, influence the normal operation of motor simultaneously.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model has designed the contactless suspension rotor of a kind of motor, thereby reaches the contactless running of rotor, avoids producing noise and heat, and then improves motor speed, efficient, increases the service life.
Technical solution of the present utility model is: respectively paste a whole magnet ring on the axle at rotor two ends, magnet ring integral body magnetizes, and divides 1,2,3 utmost points, and 1,3 is the N utmost point, and 2 is the S utmost point.Magnet ring respectively by different polarity, is fixedly sticked on the axle at rotor two ends; To respectively paste a whole magnet ring in the end cap central bore of motor two ends again, magnet ring integral body magnetizes, and divides 1,2,3 utmost points, 1, the 3 N utmost points very, and 2 is the S utmost point, its polarity is corresponding with the whole magnet ring on the rotor two end axles; End face in centre bore is pasted a ring-like magnet ring, its outside diameter is identical with whole magnet ring outside diameter on the rotor axis of electric, the polarity of its end face is identical with the end face polarity of rotor axis of electric magnet ring, the rotor axis of electric that pastes magnet ring is put in the magnet ring of motor two ends end cap central bore, make each polarity of magnet ring in magnet ring and the end cap central bore on the rotor axis of electric corresponding identical, each corresponding permanent magnet is a homopolarity, thereby reaches the purpose of repelling each other.The two ends end cap is fixed on the motor casing, and this moment, rotor axis of electric just was suspended in the magnetic field in the end cap central bore, and rotor and motor casing are without any contacting.Mentioned whole magnet ring also can be that one pole magnet ring more than 3 or 3 is pasted together in the utility model, and polarity is identical with whole magnet ring.Because therefore not contact can not produce friction, noise and wearing and tearing, can not produce heat yet, more do not need the lubricating oil of annotating, thereby improved motor performance, be specially adapted to high-speed electric expreess locomotive, reduce contact wear, avoid because the various faults that bearing mechanical friction causes.
