SERVOPACK Specifications and Dimensional Drawings
(1) Allowable Load Moment of Inertia and Motor Speed for SGMAH 200 V Servomotors
The following relationships between the motor speed and load moment of inertia are for an AC input power volt-
age of 200 Vrms. The relationship will change according to changes in power voltage.
(2) Allowable Load Moment of Inertia and Motor Speed for SGMPH 200 V Servomotors
The following relationships between the motor speed and load moment of inertia are for an AC input power volt-
age of 200 Vrms. The relationship will change according to changes in power voltage.
(3) Allowable Load Moment of Inertia at the Motor Shaft
The rotor moment of inertia ratio is the value for a servomotor without a gear and a brake.
