Linear Synchronous Motor (LSM)

Linear Synchronous Motor (LSM)

A linear synchronous motor (LSM) is much more efficient compared to a linear induction motor (LIM).

Prolim LSM drives are available both in the flat, conventional design as well as in the much more efficient Beilim arrangement, developed by InTraSys:
Prolim LSM drives are available both in the flat, conventional design as well as in the much more efficient Beilim arrangement, developed by InTraSys:

Therefore, linear synchronous motors (LSM) are ideally suited for:

  • extremely high velocities of up to 50 m/s (= 180 km/h or 110 mph)
  • high thrust of up to 200 kN (at 3.000 A)

Prolim LSM drives are available both in the flat, conventional design as well as in the much more efficient Beilim arrangement, developed by InTraSys:

  • 100% more thrust with approx. the same investment
  • standing or hanging versions
  • very low shearing forces thanks to symmetrical design

Beilim arrangement.

Prolim LSM drives and their characteristics at a glance

  • wear-free – 10 million cycles
  • very compact stator; due to special core design high slot-space factor of 60%
  • magnetic field usable across the full physical width
  • completely sealed (IP 68)
  • single stator segments are typically 800 mm (32″) long
  • air gap typically 10 mm (3/8″)
  • robust mechanical guidance required
  • secondary sheets are completely passive; no power supply or wiring required

A practical example

Left and right of the centre guiding rail, the white stators of the (standing) InTraSys LSMs are clearly visible. In centre rail and the rail on the right edge of the picture are used for mechanical guidance.
