The application of flat wire motor stators in passenger cars marks a significant advancement in motor technology in this particular field. This technology brings a number of technical advantages by using flat wires instead of traditional round wires.
Firstly, flat wire motors have significantly higher slot fullness, which means that more copper wires are accommodated in the same space, thus enhancing the magnetic field strength and power output of the motor. For example, some data shows that flat wire motors can be filled with 20-30% more wire, which somehow boosts the power of the same size motor by about 20-30%. This high power density design not only improves the vehicle's power performance, but also helps to reduce the size and weight of the motor, which is particularly important for the passenger car market, which seeks space efficiency and energy efficiency.
Secondly, the thermal performance of flat wire motors has been significantly improved. The increased contact area between the flat wires and the flat wires improves the heat dissipation efficiency of the wires and helps to control the operating temperature of the motor, thereby increasing the reliability and durability of the motor. This is essential to ensure that the motor maintains optimum performance in a wide range of driving conditions.
In addition, the flat wire motor design helps to reduce motor noise, vibration and sound vibration harshness (NVH), enhancing driving comfort. The higher stiffness of flat wire motors suppresses armature noise, while smaller slot sizes help reduce cogging torque, further reducing the motor's electromagnetic noise.
In terms of cost-effectiveness, flat-wire motors have relatively low material costs as they reduce the use of effective materials, while lowering energy consumption through improved efficiency, thus helping to reduce the running costs of the entire vehicle.
Technological advances have also posed manufacturing process challenges for flat-wire motors, such as design difficulties and process manufacturing difficulties, but these obstacles are gradually being overcome as technology develops. For example, through the use of advanced automated production lines and manufacturing technologies, the production efficiency and yield rate of flat wire motors are improving.
