SERVO MOTOR PERFORMANCE vs TEMPERATURE
SERVO MOTOR PERFORMANCE vs TEMPERATURE . George Younkin, ,MSEE. In the process of sizing a brushless dc SERVO drive on an industrial machine, little consideration is given to the effect of TEMPERATURE on the dynamic PERFORMANCE of the servomotor. Actually TEMPERATURE has a significant effect on the MOTOR time constants. The MOTOR resistance increases with TEMPERATURE as- R (T ) = R(To )[1 + (T To )]. where: T= Winding TEMPERATURE ( o C ). To = Specified TEMPERATURE (usually the cold TEMPERATURE ) ( o C ). / o C = linear TEMPERATURE coefficient for copper magnet wire.
