Coreless SGLGW/SGLGM - (with high-force magnetic ways)
Note: 1. The items marked with an * and “force and speed characteristics” are the values at a motor winding temperature of 100
°
C
during oper-
ation in combination with a servo drive. The others are at 20
°
C (68
°
F).
2. The above specifications show the values under the cooling condition when a heat sink (aluminium board) listed in the following table is
mounted on the coil assembly.
