(2) Holding Brake Moment of Inertia
The moment of inertia of the servomotor with holding brake is expressed using the following equation.
(The moment of inertia of the servomotor with holding brake) = (rotor moment of inertia) +
(brake moment of inertia)
* These values are reference values.
(3) Derating Rate for Servomotor With Oil Seal
For a motor with oil seal, use the following derating rate because of the higher friction torque.
(4) Torque-motor Speed Characteristics
(a) 100-V Class
(b) 200-V Class
