Manufacturing and Sales of SHAFTMOTOR and GRANITE AIR BEARING STAGE

●About SHAFTMOTOR
SHAFTMOTOR
The SHAFTMOTOR is a first-of-its kind linear motor that consists of a combination of a moving coil and stainless steel shaft with a built-in permanent magnet.
Features
1.Simple structure
・Simple structure consists of magnet and coil only
・Because no friction is produced, the motor is maintenance-free and produces
 no noise or dust.
・Offers high efficiency and large thrust with short coil.

2.High precision
・No friction is produced so there is no error due to heat expansion.
・Thrust is no affected by gap fluctuation.
・The outer surface of the shaft is stainless steel. Because no iron is used at all,
 there is minimal attraction between coil and shaft, and no cogging is produced.
・Because drive is non-contact, there is no structural precision error (backlash) such
 as is produced in the gaps of ball screws.

3.Facilitates mounting
・No absorption power between coil and shaft.
・Wide gap between shaft and coil, thrust not affected by eccentricity.
・Can be easily converted from conventional ball screw system.
・Shaft shape facilitates design and assembly.

4.Diverse assortment of applicable drive systems
・Adaptable to all sorts of drive systems including parallel, tandem or multi.
