It states to be intervally arranged on magnetic sheet and has multiple magnets, the magnetic pole of the two neighboring magnet is different, and each magnet is along the magnetic sheet
Width direction setting and between the length direction of each magnet and the width direction of the magnetic sheet there are migration included angle, lead to
Crossing multiple magnets attracts the electrical-coil to advance along the length direction of the magnetic sheet.
Preferably, for the migration included angle within the scope of 8 ° to 9 °, the migration included angle is 8.34 °.
Preferably, the upper and lower surface of each magnet is respectively the pole N or S, has the two neighboring of the different magnetic poles
Spacing between the magnet is 22.5mm, and the spacing between the two neighboring magnet with the identical magnetic pole is
45mm。
Preferably, the magnetic sheet is equipped with housing to cover all magnets, and the electrical-coil is slidedly arranged on the cover
On shell.
Preferably, the overall thickness of the wide 75mm of the magnetic sheet, the magnetic sheet and the magnet is 14.3mm, the electrical-coil
Width be 70mm.
Preferably, multiple mounting holes are offered on the electrical-coil, multiple mounting holes are uniformly arranged.
Preferably, induction reactance is 80mH between the line of the electrical-coil.
Preferably, 10.5 Ω of impedance between the line of the electrical-coil.
Preferably, the wide 70mm of the electrical-coil, thickness 43mm, long 290mm.
Preferably, the magnetic sheet is that multistage head and the tail are spliced, and eight pieces of magnetic poles are placed on every section of magnetic sheet.
