1. Because most of the fans and cooling fans on the market are basically AC, so we only produce AC brushless fan motors before receiving this customer's inquiry. But Mr. Ali said that the company wants to launch a DC brushless cooling fan with softer air volume and longer service life in 2023, so the voltage of the motor must be DC 24V. The brushless motor itself is an AC and DC motor, so it is not difficult to customize a brushless DC motor. But it needs to be equipped with a suitable driver. In order to meet the needs of customers, we have customized and developed a driver suitable for 24V 70W brushless fan motors for customers.

2. If the AC motor is changed to a DC motor, the power will change. In order to determine a more accurate output power of the motor for the customer to reduce energy consumption, we inquired about the use scene of the customer's motor, the size and weight of the equipped fan blades, and other information. After comprehensive consideration, it is determined that the output power of the motor is most suitable at 70W.

3. The cost of the brushless fan motor will be slightly higher than other fan motors because of its high efficiency, long life and the need to be equipped with a driver. Customers hope that we can reduce the cost of the motor as much as possible, but at the same time ensure the quality and performance of the motor. Therefore, according to the determined motor voltage, power and speed, we accurately select an AC brushless motor with the most suitable size for customization, thus avoiding the increase in material costs caused by oversized motors.
