Servomotor Specifications and Dimensional Drawings
* 1. Maximum motor speed is up to 4000 min
-1
at the shaft.
* 2. Gear output torque is expressed using the following equation.
(Gear output torque) = (servomotor output torque) × × (efficiency)
The no-load torque for a servomotor with gears is high immediately after the servomotor starts, and it then
decreases and becomes stable a few minutes later. This is a common phenomenon caused by grease being
circulated in the gear and not by a faulty gear.
The speed control range of SERVOPACKs in the Σ-II series is 1:5000. When using servomotors at
extremely low speeds (for example, 0.02 min
-1
max. at the gear output shaft) or when using servomotors
with one pulse feed reference for extended periods and in other situations that are less than optimum, the
lubrication of the gear bearing may be insufficient. This may cause deterioration of the bearing or increase
the load ratio.
Contact your Yaskawa representative if you are using your servomotor under such conditions.
