This paper presents a method to analyze thermal performance of small electric motors. A finite element software is used to evaluate dynamic flux distribution and iron losses inside the motor. A computational fluid dynamics (CFD) tool is applied to estimate the temperature distribution of the motor. A double chamber calorimeter (DCC) is used to measure the induction motor losses and efficiency. Hot-spot temperatures are also measured using thermocouples. Results of tests and computation on a fractional horsepower induction motor show good agreement between theoretical estimates and measurements. | Source Title: | Proceedings of the International Conference on Power Electronics and Drive Systems | URI: | http://scholarbank.nus.edu.sg/handle/10635/69899 |
