- Summary:
- This paper deals with studies made on the effectiveness of fins orientation, mounting direction and outer casing design of motors in terms of heat dissipation. Traction Motors are being used to drive small mobility electric vehicles and these motors mainly consist of a stator and a rotor. Torque will be induced in the rotor due to magnetic interaction between rotor and stator magnetic flux. Magnetic flux density induced in the stator depends on current passing through the stator winding, and this will be considered as the main heat-generating source for the motor. Temperature of the motor parts are very critical in terms of efficiency and reliability and should be maintained within the specification limits. Proper cooling mechanisms are to be provided for heat dissipation and heat dissipation can be achieved either by conduction or convection or by both. Forced convection can be achieved by fan cooling and the fan can be either integrated with the motor or separated. Free convection can be achieved when vehicle moves with certain velocity and natural airflow can be utilized for cooling the motor. Mounting of the motor with the integrated fan in the vehicle is found to be slightly complicated due to space limitation. If the motor is not able to integrate with the fan, a separate fan can be used. The above analyses are very critical in terms of heat transfer, which are to be considered while designing the motor
