Abstract:	The transient energy of transmission of multi stage synchronous induction coil devices is huge, which may cause damage to the motor, so it is necessary to study the temperature rise of the motor. However, considering the problems that transient thermal finite element simulation time is too long, temperature rise calculation programming of the current filament method is too cumbersome, and the workload is to large, this paper firstly applies the one dimensional thermal network model calculation method to multi stage synchronous induction coil devices for algorithm optimization. Besides, this paper equals motor heat generation to one dimensional heat transfer to derive transmitter state equation. Then, the one dimensional thermal network model of synchronous induction coil transmitters is constructed through Matlab. The simulation results show that the one dimensional calculation results are verified through the theoretical calculation without considering heat dissipation and the comparison of the three dimensional finite element calculation results, and the simulation error between the simulation results of the one dimensional thermal network model and those of the previous two is kept within 10%. Compared with transient thermal finite element simulation and the current filament calculation, the one dimensional thermal network model significantly reduces the calculation time of temperature rise of the transmitter and thus improves simulation operation efficiency on the basis of reducing the difficulty of model construction.
