Rating and Specifications for Standard Servomotors
SGMSH Standard Servomotor Ratings and Specifications
* These specifications and torque-motor speed characteristics are quoted in combination with an
FSP amplifier operating at an armature winding temperature of 20°C.
Note: These characteristics have been calculated with the following aluminum heat sinks attached for
cooling:
