    Abstract: To improve the calculation accuracy of motor thermal field, this paper proposes a method for calculating the equivalent thermal conductivity of winding based on conductor distribution, and a 24-slot 26-pole outer-rotor permanent magnet synchronous motor is taken as an example to verify the method. First, the equivalent thermal conductivity of winding is calculated by traditional equivalent methods, namely the equivalent insulation layer method and the area weighting method. Second, the equivalent thermal conductivity of the slot winding and end winding in the three-dimensional (3D) direction is derived using the conductor distribution method. Third, the 3D finite element models corresponding to three equivalent methods are established, and the temperature of the motor under different operating conditions is simulated and compared. Finally, an experimental platform is built to verify the accuracy of the proposed conductor distribution method.
