Linear synchronous motor LP32-359-50-GT1-A
 
Overall and join dimensions of linear synchronous motors series LP-32
 

           

 

The linear synchronous motors Ruchservomotor JV are guarantee:
high force density in compact dimensions(peak linear force up to 7600N),
high velocity(up to 5m/s)
and accelerations (up to 14G *).

Multiples forcers can be operated independently on one magnet way. The motors can be join serially or in parallel for obtaining higher linear force.

Short description:


The AC servomotor consist of a moving primary coil unit (forcer) and a secondary permanent magnet unit (magnet way).
The forcer includes a coil unit that is encapsulated in thermally conductive epoxy.
The magnet way is made of high-energy rare-earth magnets glued on a steel plate.
An air gap between forcer and magnets must be maintained according to the specified dimension tolerances for proper operation of motor.

The iron-core motors are equipped by one magnet way (track), placed under the forcer.
Therefore high attraction force is appear between magnet way and forcer.
This force guarantee high rigidity of linear system, provide preload for linear guideways. The high magnetic attraction force is between magnet way and forcer. This feature garantee high rigidity of linear system, provide preloading on linear guideways system.
