摘要：
This paper presents a technique to optimize the relation torque-temperature in inverter-fed induction motors for speeds below the base speed. As it is very known, the ventilating system is not efficient for low speeds, demanding a torque derating in order to keep the temperature rise unchanged. The aim of this paper is to present a voltage/frequency curve that minimizes total losses of the motor in dependence on the frequency for constant torque.
