Abstract
The utility model discloses a magnetically levitated electric motor, which comprises a rotor shaft and a housing on which the rotor shaft is mounted. Plane magnets with the same polarity are correspondingly arranged on the rotor shaft and at one end of the housing where the rotor shaft is supported; the end part of the rotor shaft is tapered at the other end of the housing where the rotor shaft is supported; and the tapered pinnacle is in point contact with a rear end cover of the housing. The utility model can completely solve the mechanical resistance force generated by the contact friction due to the axial force during operation of the electric motor. When in use, the electric motor with the structure provided by the utility model has the advantages of low energy consumption, no friction noise during normal operation, high efficiency, long service life, etc. Meanwhile, as no mechanical friction is generated, lubricant charging as well as frequent inspection and maintenance are unnecessary, thereby ensuring long-term and stable operation of the electric motor.
Description
Technical field
The utility model belongs to motor technology, is specifically related to a kind of maglev type motor.
Background technology
Existing motor often will be subjected to the effect of various resistances in the running: as shown in Figure 1, and by the axial tension F1 of load generation; As shown in Figure 2, the gravity F2 that produces by rotor part self; Perhaps as shown in Figure 3, simultaneously by the axial tension F1 of load generation and the gravity F2 of rotor part self generation.The motor operate as normal must overcome these resistances.These resistances can strengthen the friction of mechanical parts, cause motor shortening in useful life, and energy consumption strengthens, and the efficiency conversion reduces, and produces problems such as environmental noise.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of axial force unresisted maglev type motor.
Realize that the technical scheme that the utility model purpose adopts is: a kind of maglev type motor, comprise armature spindle, the casing of armature spindle is installed, on armature spindle, the identical plane magnet of polarity is set with the support zone correspondence of casing one end upper rotor part axle; At the support zone of casing other end armature spindle, the armature spindle end is taper, and its cone point contacts with casing rear end lid point.
Described plane magnet is a permanent magnet.
Because it is identical with plane magnet polarity on the casing to be located at armature spindle, no matter motor is all offset by the magnet repulsion of same polarity at load pulling force that axially produces and vertical gravity, make armature spindle be limited in the body upper magnet repulsion scope axially being in, form contactless suspended state, thereby eliminate frictional resistance.And at rotor shaft rear end cone point and end cap with a form that contacts, can eliminate the design surplus energy of the magnetic force that repels each other, reduce friction.The relation of rotor axis of electric and casing is become by original load pulling force and vertical gravity has only the radial location correction of external force under causing contacting between them.The mechanical resistance that causes contact friction to produce by axial force in the time of can thoroughly solving machine operation.Adopt the motor of the utility model structure to have advantages such as energy consumption is low, operate as normal does not have the frictional noise generation, efficient height, life-span length.Owing to there is not mechanical friction, the lubricating oil of needn't annotating also can be checked and be keeped in repair frequently simultaneously, and motor can move steadily in the long term
Further specify the technical solution of the utility model below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 to Fig. 3 is respectively an axially loaded situation schematic diagram when having machine operation now.
Fig. 4 adopts structural representation of the present utility model.
Embodiment
See Fig. 4, the maglev type motor comprises armature spindle 3, the casing 5 of armature spindle is installed, and with the support zone correspondence of casing 5 one end upper rotor part axles the identical plane magnet of polarity 1,2 is set on armature spindle 3; Support zone at casing 5 other end armature spindles is provided with copper bush 4, and armature spindle 3 ends that are positioned at copper bush 4 are taper, and its cone point contacts with 6 of shell end covers.
The plane magnet is a permanent magnet.
