Novel magnetic levitation axial telescopic motor

Abstract

The invention discloses a novel magnetic levitation axial telescopic motor. The motor comprises a motor shell and a motor shaft branch, the motor shaft branch is arranged at the axis of the motor shell, a front end cover is arranged at one end of the motor shell, a rear end cover is arranged at the other end of the motor shell, and shaft holes are formed in the axis of the front end cover and theaxis of the rear end cover. Stator teeth attract the magnetic steel in the axial direction and the radial direction, and a preset value exists in the axial direction, so magnetic levitation of a rotorassembly is achieved, and shaft branches of the upper and lower transmission motors can be stabilized without a guide rail sliding block mechanism; the current direction is switched through an external circuit, the power-on time is controlled, so the rotor does up-down reciprocating motion, and motion transmission is achieved through the electromagnetic effect; and the motor is of a multi-pole structural design, and a plurality of transmission units are combined, and the motor in unit volume can transmit larger numerical power, so the size of the motor is reduced under the condition that therated power is achieved, and the maximum energy efficiency can be achieved in a limited space.

Description

technical field [0001] The invention relates to the technical field of magnetic levitation motors, in particular to a novel magnetic levitation axial telescopic motor. Background technique [0002] With the continuous improvement of people's living standards, electric toothbrushes have begun to enter people's daily life, replacing traditional toothbrushes to achieve a more ideal and convenient brushing effect. Existing electric toothbrushes are usually driven by a motor, which cleans the teeth through the vibration of the toothbrush head. [0003] The motion track of the output shaft of the motor device used in the existing electric toothbrush is generally radially left and right, and the axial expansion is less. Realizing axial movement often requires the use of a guide rail slider mechanism, and the motor has a complex structure, large volume, and obvious noise. It is precisely because of the above problems that the axial magnetic levitation motor was born. However, the...
