When sizing a motor, one of the most important factors is the required torque. In general, motor torque-speed curves outline two primary areas of permissible torque: continuous and intermittent.
Intermittent motor torque is allowed only for a short time and in most cases is the torque required during acceleration. Continuous torque is determined by calculating the root mean square of all the torques that occur throughout the application, which typically include torque during acceleration, torque during constant speed, and torque during deceleration.
