3 Specifications and Dimensional Drawings
3.7.1 Small-capacity Series SGMCS Servomotors
3-40
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 100°C (212°F). Other values
quoted at 20°C (66.2°F).
* 2. Rated torques are continuous allowable torque values at 40°C (104°F) with a iron heat sink
attached.
