    • Rotational speed of an electric turbocharger controlled so that the actual temperature of the motor does exceed the allowable level even over a long time span. A speed control device for the turbocharger, includes a temperature sensor, a speed limitation device which limits the speed of the motor in response to the temperature level detected by the temperature sensor wherein the speed limitation device is provided with a limit control start temperature correction device which decreases the limit control start temperature when the increase rate of the detected temperature exceeds a threshold. A speed limitation setting device sets a speed limit based on the temperature difference between the limit control start temperature and the detected temperature T on a rate of increase of the detected temperature.
    • 电动涡轮增压器的转速被控制,使得电动机的实际温度即使在很长的时间内也能超过容许水平。 一种用于涡轮增压器的速度控制装置,包括温度传感器,速度限制装置,其根据由温度传感器检测到的温度水平来限制电动机的速度,其中速度限制装置设置有限制控制开始温度校正装置 当检测到的温度的增加率超过阈值时,这降低了限制控制开始温度。 速度限制设定装置根据检测温度的上升速度,设定基于限制控制开始温度和检测温度T之间的温度差的速度限制。
