Technical field:
But the present invention relates to a kind of bilinear permanent magnet synchronous motor horizontally-feeding platform of offsetting influence of gravity.
Background technology:
Digit Control Machine Tool is the important foundation of manufacturing processing machine tool and national economy.It provides equipment and means for each department of national economy, has the economy and society effect of unlimited amplification.
The linear electric motors drive system is current the most promising high speed of generally acknowledging in the world, the feed system of high precision machine tool.Along with at a high speed, the continuous development of ultrahigh speed processing, linear electric motors are applied to various lathes and machining center more and more widely, wherein, being most widely used of permanent-magnetism linear motor.
Permanent-magnetism linear motor also can produce the normal direction magnetic attraction perpendicular to direction of feed between elementary and secondary except generation is parallel to the electromagnetic push of the direction of motion, its numerical value is approximately about 10 times of thrust.This normal direction magnetic attraction does not normally wish to exist, because the magnetic attraction that single side type permanent-magnetism linear motor drive system produces has increased the pressure between line slideway and the slide block, and then frictional force is between the two increased, and has reduced the dynamic property of Digit Control Machine Tool.At present mainly by adopting double-flanged end structure Design method to solve the problem that the normal direction magnetic attraction causes.But because employed linear electric motors mostly can't be made double-flanged end on Digit Control Machine Tool, this just has higher requirement to the Digit Control Machine Tool rigidity of structure, therefore when carrying out the machine tool structure design, must consider this normal direction magnetic attraction.
