3.7.2 Middle-capacity Series SGMCS Servomotors
(1) Ratings and Specifications
Note: 1. SGMCS servomotor with holding brake is not available.
2. For the bearings used in SGMCS servomotors, loss varies according to the bearing tem-
perature. At low temperatures, the amount of heat loss will be large.
* 1. These items and torque-motor speed characteristics quoted in combination with an SGDM
SERVOPACK are at an armature winding temperature of 20°C.
* 2. Rated torques are continuous allowable torque values at 40°C with an iron heat sink attached.
