Linear Step Motors
Planar Concern has been designing and manufacturing linear
step motors since 1962. The range of motors includes
one-axis, two-axes, multi-axes, rotary motors, motors with feedback as well.
Advantages of linear step motors over other transmission mechanisms:
- simple mechanical construction;
- absence of lead screws, driving gears, etc;
- easy to make systems with several objects moved
independently in one plane
- small overall dimensions and weight of movable parts;
- high dynamic characteristics;
- low noise level;
- absence of wear of aerostatic bearings
- high reliability;
- environmental cleanliness;
Application:
- Equipment for semiconductor industry (laser pattern generators, wafer steppers, inspection and measurement systems, probers, wire bonders, die bonders, etc.)
- Equipment for electronics industry (PCB equipment, SMT equipment, laser processing equipment, visual inspection equipment, transport and handling systems, etc.)
- Machine building, robotic engineering and other industries.
In addition to our standard models we can design and produce LSMs and LSM-based systems on customer’s requirements.
