2. LINEAR SERVO MOTOR
2.2.2 Inspections on secondary side (magnet)
(1) Attachment of water and oil
Check that the primary side (coil) and secondary side (magnet) have not got wet with water and oil. When
the linear servo motor has got wet, the insulation on the primary side (coil) is deteriorated, which may cause
failure. Make sure to establish the mechanical structure in which water and oil are not attached to the linear
motor.
(2) Exposure and lift of magnet
Check for the exposure and lift of the magnet on the secondary side (magnet). If the magnet on the
secondary side (magnet) is exposed or lifted, replace the secondary side (magnet) immediately.
(3) Molded resin
(a) Check for missing or cracks of the mold resin on the secondary side (magnet). (a) When missing or
cracks are found in the molded resin on the secondary side (magnet), replace the secondary side
(magnet).
(b) Check for the scratches of the molded resin on the secondary side (magnet). When the magnet is
exposed by the scratches of the molded resin on the secondary side (magnet), replace the secondary
side (magnet). When a foreign matter is caught in the empty clearance between the primary side (coil)
and the secondary side (magnet), a scratch occurs on the secondary side (magnet). In such case, take
away the corresponding matter and establish the mechanical structure which does not catch such
matters.
(4) Loose mounting screws
Check for loose mounting screws on the secondary side (magnet). When the mounting screws on the
secondary side (magnet) are loose, tighten the corresponding screws.
2.2.3 Inspections of linear encoder
The inspections of the linear encoder may be required. For the inspections of the linear encoder, contact the
linear encoder manufacturer.
