In view of the narrow installation space of high power density and high torque in-wheel motor, the heat existed the in-wheel motor is balanced by cooling water channel to ensure the heat dissipation of the high power density in-wheel motor. In this paper, Ansoft Maxwell software is used to establish the twodimensional loss simulation model of in-wheel motor, and the winding loss, stator core loss, rotor core loss and permanent magnet eddy current loss of in-wheel motor are calculated respectively. The temperature field calculation model of in-wheel motor is established. The heat exchange coefficient of motor is calculated, and the equivalent treatment of windings is carried out. The spiral channel is selected to cool the motor. The CFD software is used to simulate and analyze the cooling fluid in the channel. The heat dissipation coefficient curve is calculated. Finally, the calculated results of in-wheel motor loss and heat dissipation coefficient curve are imported into the transient temperature field for simulation, and the temperature field distributions before cooling and after cooling are obtained. The results show that the temperature drop of winding is 32%, the temperature drop of stator core is 30%, the temperature drop of permanent magnet is 26%, and the temperature drop of rotor is 25%. The spiral channel structure adopted in this paper is reasonable and feasible, which provides a certain theoretical reference value for the research and development of in-wheel motor heat dissipation system.INDEX TERMS Electric vehicle, in-wheel motor, loss calculation, fluid field, water cooling.

“…Vector control technology has produced a classic control scheme, which is widely used in the electric drive industry. According to whether or not it is desirable to decouple, the vector control technology can be further divided into field-oriented control (FOC) [6], direct torque control (DTC) [7,8], etc. Over the years, motor systems have required fast current response and small fluctuation for PMSMs in high-precision, high-performance control problems; therefore, many scholars have carried out research at home and abroad, and various advanced control methods have been applied to the field of motor control, e.g., model predictive control (MPC) [9][10][11], sliding mode control [12,13], fuzzy control [14,15],…”

In this paper, a finite control set model-free predictive current control (FCS-MFPCC) of a permanent magnet synchronous motor is presented. The control scheme addresses the problems of large current fluctuation and decline of the motor system performance during parameter perturbation for the traditional finite control set model predictive current control (FCS-MPCC). Firstly, the mathematical model of the motor is analyzed and derived during parameter perturbation, and a new hyperlocal model of the motor is established based on this mathematical model. Secondly, a finite control set model-free predictive current controller is designed based on the new hyperlocal model, and a current error correction factor is introduced to correct the prediction error. Meanwhile, the stability of the observer is demonstrated via the Lyapunov theory. The simulation results show that the proposed control strategy reduces current fluctuation compared with the FCS-MPCC strategy, and the system is robust during parameter perturbation.
