It is an electric vehicle with four independent inwheel motors.
Half shaft dynamics are not modelled since the motors are of inwheel configuration.
According to above analysis, the object of the present study is thermal loss and temperature field of inwheel motor in micro-electric vehicle.
Permanent magnet of inwheel motor adopts Nd-Fe-B, which possesses the satisfactory magnetic flux density performances, but its temperature coefficient is high and its heat resistance is bad.
where [P.sub.sN] is the stray loss when the output power of the inwheel motor is in rated power, and [I.sub.N] is the rated current of the in-wheel motor.
The air gap between stator and rotor was dealt with, and the revolving rotor made the air of air gap flow when the inwheel motor was running.
7 show that the load of in-wheel motor is more than 110 kg or the revolving speed of inwheel motor is more than 1800 r/min, and the temperature of winding and stator can be more than 100 [degrees]C, which can lead to the overheating of in-wheel motor, the burning out of winding insulation layer, the failure of Hall sensor and the demagnetization of permanent magnet, and even seriously the in-wheel motor to stall.
In addition, Table also shows that the range of temperature is small among the parts, which indicates the inwheel motor has a good heat transfer effect.
