12. SERVO MOTOR
(2) Torque characteristics
POINT
For the system where the unbalanced torque occurs, such as a vertical axis,
the unbalanced torque of the machine should be kept at 70% or lower of the
motor's rated torque.
The torque characteristics shown in the following diagrams are for the servo motor alone. When the input
power supply specification of the servo amplifier is 1-phase 230 V AC, the torque characteristic is indicated
by the heavy line. For 1-phase AC 100 V, part of the torque characteristics is indicated by a broken line,
and for 1-phase 200 V AC part of the torque characteristics is indicated by a continuous line.
