Servo Motor Torque-Motor Speed Characteristics (200V Models)
* The characteristics are the same for three-phase 200 V and single-phase 200 V.
Note: 1. These values are for operation in combination with a SERVOPACK when the temperature of the armature winding
is 100°C. These are typical values.
2. The characteristics in the intermittent duty zone depend on the power supply voltage.
3. If the effective torque is within the allowable range for the rated torque, the Servo Motor can be used within the
intermittent duty zone.
4. If you use a Servo Motor Main Circuit Cable that exceeds 20 m, the intermittent duty zone in the torque-motor
speed characteristics will become smaller because the voltage drop increases.
*
The moment of inertia for the Servo Motor and gear is the value without a holding brake. You can calculate the moment
of inertia for a Servo Motor with a Gear and Holding Brake with the following formula.
Motor moment of inertia for a Servo Motor with a Holding Brake from Ratings of Servo Motors (200 V Models)
(page 24) + Moment of inertia for the gear from the above table.
The SERVOPACK speed control range is 5,000:1. If you use Servo Motors at extremely low
speeds (0.02 min
-1
or lower at the gear output shaft), if you use Servo Motors with a one-pulse
feed reference for extended periods, or under some other operating conditions, the gear bear-
ing lubrication may be insufficient. That may cause deterioration of the bearing or increase the
load ratio.
Contact your Yaskawa representative if you use a Servo Motor under these conditions.
