Abstract:
The article presents a proposed thermal model for asynchronous motors range of small capacitỵ. Based on the analysis of the announced models [1, 2, 6], the authors analyzed their advantages and disadvantages, then proposed a simple and more accurate calculation model. For current thermal model, there are two basic approaches: Thermal parameter model (analytical method) and íhe thermal shields model (numerical meíhod). The authors focus on analyzing and proposing model for for three phase small capacity asychronous motor fo1low the type of parameter thermal model.
