LINEAR PLANAR STEP MOTORS (dual axes XY stepping motors)

two planar servomotors with Hall-sensors feedback

 Short design description of planar motor.

A linear planar stepping motor consists of a forcer and stator . The stator of step motor is made as a flat plate that carries on its working surface a spaced toothed structure. The forcer contains two groups of orthogonal electromagnetic modules. The working surface of electromagnetic modules has a spaced toothed structure with a definite phase shift from pole to pole. To create an air cushion between one stator and the forcer the latter is provided with a built-in pneumatic system with jets.
We are produce two types of motors: planar motor without position feedback and planar servomotor with with Hall-sensors (HS) feedback.

Advantages and specific features:

• The Ruchservomotor JV planar servomotors - the planar step motor (XY) motor can make rotary movement at staying in position within +/- 2 thread periode of stator(as usually 1 periode=0.64 or 1.00mm) (motors with Hall-sensors feedback only).
• Air-magnetic bearing - guarantee excellent repeatability and high durability of coordinate system
• Free motion in two axes.
• Positioning in any space of plane.
• High velocity, up-to 1,7m/s
• Compact, low profile design.
• Simple design of a multi-coordinate system in one stator by increasing the number of forcers.
• Possible to operate up side down or on sloping stator surface
• Several coordinate systems with intersecting trajectories in one plane are possible.

• Assembly operations in microelectronics and instrument engineering:
• LSI and VLSI unwelding.
• Probe monitoring.
• Crystal fitting.
• Surface mounting elements and units assembly.
• Printed circuit board control.
• Laser technological complexes.
• Measuring machines.
