A novel approach for temperature estimation in squirrel-cage induction motor without sensors

Temperature Supervision of an Integrated Starter Generator

“…By considering all the heat sources in the machine, mainly due to joule losses, temperature can be analytically estimated [15]. However too much detailed models, constituted of several tens of elements have to be avoided in the objective of real time implementation [16]. Moreover, because of the starter generator location, the internal combustion engine provides another heat source which is not easy to evaluate (Fig.…”

Intelligent Sensor Based Bayesian Neural Network for Combined Parameters and States Estimation of a Brushed DC Motor

“…According the literature [11][12][13][14][15], we can distinguish two types of electrical machines thermal modeling approaches:…”

“…The first one is thermal model-based approaches, this approach based to divide the machine into homogeneous components unscrewed in order to ensure each part has uniform thermal characteristics such as thermal capacitors, thermal resistances and heat transfer coefficients [11,15]. The identification of the model is performed either by the finite element technique or by a high range of temperature measurement.…”

“…These models are generally very detailed so, too complex for real time application [16], however, many researchers simplify this model for the real time applications [15,17]. This approach is robust, unfortunately this model is not generalized and a few measurements are needed for each motor [11,16].…”

Online Sensorless Induction Motor Temperature Monitoring

“…Temperature estimation methods based on thermal and electromagnetic motor models are found in literature [3], [4]. However, these methods fail when the model changes, for instance, due to cooling system failures or its dependence on operating conditions (e.g., fan speed).…”
