The heat dissipation performance of the motor is an important indicator affecting the performance of the motor. Especially for high-efficiency and high-efficiency motor products, how to use the minimum air volume to achieve heat dissipation of the motor becomes more important.
As a kind of power source, the motor will inevitably generate heat during operation due to conductor resistance and magnetic flux leakage. The accumulation of these heat will damage the insulation performance of the motor coil, damage the bearing lubrication, reduce the reliability of the equipment, and even cause The motor is damaged.
High-efficiency motors, because of their high efficiency requirements, require manufacturers to optimize the design of each component during the design and manufacturing process, reducing the useless losses generated by the motor, from the use of high-quality punching and bearings to the use of high-quality cast aluminum Even the energy consumed by the cooling fan should be accurately calculated and optimized as much as possible so that the device can provide maximum power output while satisfying heat dissipation. Therefore, high-efficiency motors use special fans and hoods. These fans have a smaller area than conventional efficiency motors and therefore consume less energy. However, we use aerodynamics to optimize them, but they can be combined with special hoods. Ordinary motor equivalent cooling effect. This optimization method has been well applied in high-efficiency motors and even ultra-efficient motors, which can ensure the heat dissipation capability of the motor while reducing energy consumption.
