Forcer of Linear synchronous motor LC32-167-30-B
with stator LW32-256-30
 
Overall and join dimensions of linear synchronous motors series LC-32
 

          

Linear motorsare a special type of synchronous motors
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).

Example order key -Primary part (forcer with iron core, windings and cable):
LC32-167-50-C-HT1-1000-N0-B, where LC32-, 167-Length of forcer, 50-width of Iron core, C-no cooling, HT1 - Coil wire code, 1000-length of Motor cable, N0-N0-no connector , B-bottom mounting,


Example order key - Secondary part (stator, magnet way with permanent magnets):

LW32-512-50-A, LW32-, 512 (ore 256,128,64-length), 50-width of Iron core, A-top mounting,

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.

Advantages
- Low profile
- high accuracy, repeatability and resolution, high dynamics characteristics,
- absence of mechanical transmission,
- no backlash,
- attraction force between forcer and magnet way is used for preload of linear bearing.
