Abstract
The utility model relates to a magnetic suspension motor which comprises a motor shell, wherein a stator and a rotor are installed on the motor shell, the rotor is connected with a motor shaft, the motor shaft is in threaded connection with the motor shell, and when the motor shaft rotates, the motor shaft slides axially relative to the motor shell. In the magnetic suspension motor, after high-frequency alternating current is input, the motor shaft can rotate back and forth slightly to generate vibration, and due to the fact that the motor shaft is in threaded connection with the motor shell, the motor shaft can slide back and forth slightly along the motor shell under the action of the threaded structure when the motor shaft rotates, so that the motor shaft can vibrate in multiple directions.
Description
Technical Field
The utility model relates to a magnetic suspension motor.
Background
Magnetic suspension motor is one kind under the high frequency alternating current drive, can make a round trip slight rotation, and then realize the motor of vibrations, and this motor wide application is on electronic toothbrush, but current magnetic suspension motor usually can only make a round trip slight rotation, uses under the electric toothbrush condition, and the vibrations effect is relatively poor, and clean dynamics is not enough.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects in the prior art, the utility model provides a magnetic suspension motor which is realized by the following technical scheme.
The utility model relates to a magnetic suspension motor which comprises a motor shell, wherein a stator and a rotor are installed on the motor shell, the rotor is connected with a motor shaft, the motor shaft is in threaded connection with the motor shell, and when the motor shaft rotates, the motor shaft slides axially relative to the motor shell.
Further, the motor shaft is provided with the external screw thread, the motor casing is provided with the internal thread, the motor shaft pass through external screw thread, internal thread in order to realize with the motor casing spiro union.
Further, the external thread that the motor shaft set up is the bull external thread, the internal thread that the motor casing set up is the bull internal thread.
The utility model has the beneficial effects that: compared with the prior art, in the magnetic suspension motor, after high-frequency alternating current is input, the motor shaft can rotate back and forth slightly to generate vibration, and due to the fact that the motor shaft is in threaded connection with the motor shell, the motor shaft can slide back and forth slightly along the motor shell under the action of the threaded structure when the motor shaft rotates, so that the motor shaft can vibrate in multiple directions.

Fig. 1 is a structural view of a levitation motor of the present invention.
Detailed Description
The present invention is further illustrated by the following examples, which are only a part of the examples of the present invention, and these examples are only for explaining the present invention and do not limit the scope of the present invention.
As shown in fig. 1, the present invention provides a magnetic suspension motor, which includes a motor casing 1, wherein a stator 2 and a rotor 3 are installed on the motor casing 1, the rotor 3 is connected with a motor shaft 4, the motor shaft 4 is screwed with the motor casing 1, and when the motor shaft 4 rotates, the motor shaft 4 slides axially relative to the motor casing 1.
In the magnetic suspension motor, after high-frequency alternating current is input, the motor shaft 4 can rotate back and forth slightly to generate vibration, and due to the fact that the motor shaft 4 is in threaded connection with the motor shell 1, when the motor shaft 4 rotates, the motor shaft 4 can also slide back and forth slightly along the motor shell 1 under the action of the threaded structure to realize vibration of the motor shaft in multiple directions. In the utility model, when the rotor rotates in a reciprocating way within a certain angle, the axial sliding distance range of the motor shaft relative to the motor shell is in direct proportion to the thread pitch, and the value range of the thread pitch of the thread structure is set to be 0.2mm-10 mm.
Further, the motor shaft 4 is provided with external threads 41, the motor casing 1 is provided with internal threads 11, and the motor shaft 4 is screwed with the motor casing 1 through the external threads 41 and the internal threads 11.
Further, the external thread 41 that the motor shaft set up is the bull external thread, the internal thread 11 that the motor casing set up is the bull internal thread.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model as defined by the appended claims.
