3.1 Ratings and Specifications of SGLGW/SGLGM
3-3
3
(b) With High-force Magnetic Ways
The following table shows the ratings and specifications when the high-force magnetic ways are used.
Note: 1. The items marked with an * and “Force and Speed Characteristics” are the values at a motor winding tem-
perature of 100
°
C
(212
°
F) during operation in combination with a SERVOPACK. 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.
3. The values of peak speed in the table indicate the maximum speed that can be controlled from
SERVOPACK. Refer to Force and Speed Characteristics for the actual motor peak speed.
