1,000-r/min Servomotors (With a 200-VAC Servo Driver)
The following graphs show the characteristics with a 3-m standard cable and 200-V AC input.
●
• W-series AC Servomotors use rare earth magnets (neodymium-iron magnets). The temperature
• Generally, in a mechanical system, when the temperature drops the friction torque increases and
• An increase in load friction torque visibly increases load inertia. Therefore, even if the Servo Driver

coefficient for these magnets is approximately − 0.13%/ ° C. As the temperature drops, the Servomo-
tor's momentary maximum torque increases, and as the temperature rises the Servomotor's
momentary maximum torque decreases. When the normal temperature of 20 ° C and − 10 ° C are
compared, the momentary maximum torque increases by approximately 4%. Conversely, when the
magnet warms up to 80 ° C from the normal temperature of 20 ° C, the momentary maximum torque
decreases by approximately 8%.
the load torque becomes larger. For that reason, overloading may occur at low temperatures. In
particular, in systems which use deceleration devices, the load torque at low temperatures may be
nearly twice the load torque at normal temperatures. Check with a current monitor to see whether
overloading is occurring at low temperatures, and how much the load torque is. Likewise, check to
see whether there abnormal Servomotor overheating or alarms are occurring at high temperatures.
parameters are adjusted at a normal temperature, there may not be optimal operation at low tem-
peratures. Check to see whether there is optimal operation at low temperatures too.
