Brushless motor magnetic steel magnetic film is an important process, including now, many motor manufacturers are still using manual mode, relatively low efficiency, less magnetic sheet is good, magnetic sheet is more difficult to engage; if the magnetic plate magnetic force is strong, it is easy to hurt the hand, naturally, young people are not willing to dry, so how to solve the problem of automatic magnetic chip?
In order to solve the problem of magnetic steel insertion, there are now many special magnetic steel machine equipment, which can be used for different shapes of magnetic steel insertion magnetic sheets, can be manually dispensed, can also be automatically dispensed, and can also be made into production lines, relative to the manual mode, the efficiency has been greatly improved, saving manpower.
Common shapes of magnets:
1. Square, generally common power tool brushless motor, magnetic plate hole is square shape, need to insert 4 magnetic sheets, relatively simple, this artificial mode can also be accepted, the number of pieces is relatively small.
2. Round, the general magnetic plate hole is in a circular shape, evenly distributed on the surface of the magnetic steel, or inside, the number of pieces is small, there are also more, like electric vehicles, can be as high as dozens of pieces, artificial mode is relatively slow.
3. Special-shaped, magnetic plate hole is in an irregular state, common such as V-shaped, double V-shaped, etc., many new energy electric vehicle magnets are these shapes, relatively speaking, this magnetic steel machine equipment will be a little more difficult, and some even have to be inserted many times to solve.
Magnet loading method:
1. Push-in
Also called insertion, the magnetic sheet is inserted into the magnetic steel hole, because it is a fixed hole, the general position is aligned, and the fit of inserting it is relatively high, which is also a relatively simple way.
2. Fit
There are surface-mounted, and inner-paste, that is, the tile is attached to the outside of the rotor, or pasted to the inner ring, which is relatively demanding.
Push magnet, tile configuration:
Cylinder push magnet:
The use of cylinder push magnet steel mode, the speed of uniform speed insertion, there is a bad point is that the speed can not be controlled, there may be damage to the magnetic sheet, the cost is relatively low.
Servo motor push magnet:
The use of servo motor to push the magnet, you can accurately control the speed of the speed, especially when the magnetic sheet is inserted into the magnet, the speed needs to be slower, the servo motor can do it, and the cylinder is not so flexible, of course, the use of servo motor, the cost will be more expensive, but the stability is better, the magnetic sheet is not easy to damage.
In addition, the magnet machine can also be combined with the motor production line, first automatic dispensing, and then insert the magnetic sheet, no manual operation, automatic completion, higher efficiency, but also the future development mode!
Automatic insertion of magnet machine magnet loading method and shape difference, after reading the above content, do you understand!
