Influence of Magnetic Attraction
6.1.1
SGLF Servomotors
The Moving Coil and Magnetic Way face each other, so magnetic attraction will occur. Consider
the following magnetic attractions when you design the equipment.
*1.
Gap values are given for the design value minus 0.3 mm.
*2.
The maximum force is given for the magnetic attraction.
*3.
Dimensions in parentheses are for when the magnet cover is attached.
