LINEAR SYNCHRONOUS MOTORS SERIES LSM-32


Forcer and magnet way of linear synchronous motor LSM-32 series

         The linear synchronous motors Ruchservomotor JV are guarantee high force dencity 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.

Glossary for linear synchronous motors

Notes:
1.  Motor has peak force at peak current IP (2…3 ñåê)
2.  Air gap between forcer and magnets – 0,9 mm*.
3.  The maximal temperature of magnet way should be less than 70°C.
4.  [S/T] - values at Star/Triangle connection of phases.
5. The magnets are covered by stainless steel.
6. All data tolerance ±10%.
7. * - value for reference.
