• 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 the
• 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 mo-
mentary 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%.
load torque becomes larger. Therefore, 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 is 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 temper-
atures. Check to see whether there is optimal operation at low temperatures too.
