Magnetic-Thermal Coupling Analysis and Experimental Study of Extended Range Generator
With the growing maturity of new energy technology,extended-range generator is becoming more and more important for the development of new energy electric vehicles.The nature of the extended-range generator is permanent magnet synchronous mo-tor,which is characterized by small volume,large power and high calorific value.Therefore,it is particularly important to calcu-late the loss of the generator and analyze its steady-state operating temperature.Therefore,a new type of cooling channel is built to reduce the calorific value generated by the generator.Firstly,Maxwellwas used to build a two-dimensional model of the Motor,and an equivalent thermal network model was established by Motor-CAD.Finite element analysis method was used to carry out the mag-netic-thermal bi-directional iterative coupling of the Motor,and cooling channels were added to analyze the electromagnetic perfor-mance of the Motorand the temperature rise of the Motorin the steady state operation.Finally,the accuracy of the magneto-thermal coupling method for temperature field analysis was verified by the prototype test.
