(The moment of inertia of the servomotor with holding brake) = (rotor moment of inertia) +
(brake moment of inertia)
(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
