“…It is very important to monitor the rotor temperature on-line for the safe operation of the large and mediumsized motor [1] [2]. Due to the thermal effects of the winding current and internal eddy current, the motor would fever during the operation and the permanent-magnet motor temperature would rise, which might cause irreparable injury to the insulation of the winding and permanent-magnet material of the motor when serious cases, shorten the motor operating longevity, and generate detrimental effect on the safe operation of the power systems.…”

A novel structure of dynamic model is proposed in this paper and applied to construct a dynamic model to correct the dynamic errors of the infrared thermometer, because of which the dynamic performance of the thermometer is effectively improved. The dynamic compensator is established and the compensation is described and explicated by the Wiener model. According to Wiener model, the novel structure is devised. The identification of thermometer non-linear dynamic compensator is achieved by immune clone selection algorithm. The results show that the stabilizing time of the thermometer is reduced less than 7 ms from 26 ms and the dynamic performance is obviously improved after compensation.

“…Papers [2], and [3] are interesting reviews of the different factors that affect temperature and life of TEFC induction motors, including considerations of the applicable standards and suggested rules of thumb to enhance motor longevity. In [4] authors report an extensive investigation of the surface and internal temperatures of inverter-fed TEFC induction motors that will operate in a Class I, Division 2 hazardous area, in order to verify that motor temperatures will not become a source of ignition of flammable gases or vapors. This testing program includes the effect of motor load, incorrect flux level and different carrier frequencies of the PWM inverter, in the range of 10 Hz to 90 Hz.…”
