The motor structure has the advantages of small volume occupation, simple structure, low manufacturing difficulty, and low cost.
Description
Technical field
The invention belongs to motor construction technical field, more particularly to a kind of rotary motion directly becomes linear motion
Electric machine structure.
Background technology
Motor, according to the difference of movement output form, can be divided into electric rotating machine and linear electric motors, and electric rotating machine is the biggest
Well known, it is also a most widely used class motor.
Using Motor drive load, and output rotary motion or linear motion on demand.When needing to export rotary motion,
Directly requirement can be met by electric rotating machine；If necessary to linear movement output, it is necessary to coordinate when using electric rotating machine
Screw-nut mechanism or pinion and rack etc. carry out the conversion of motion mode, and not only volume takies greatly this mode, and
And it is more complicated to install maintenance process；If using during linear electric motors although directly linear movement output can be carried out, but straight line
Electric machine structure is complicated and manufacture difficulty is big, and cost is more much higher than electric rotating machine.
Therefore, when needing linear movement output, existing electric rotating machine and linear electric motors all still have several drawbacks it
Place if it is possible to overcome above-mentioned deficiency, and design a kind of have concurrently electric rotating machine and linear electric motors each advantage electric machine structure then
Very necessary.
