How to choose a brushless motor for model aircraft? Here are some tips!

For those who enjoy model aircraft, the selection of brushless motors for model aircraft is very important. Since the usage environment varies, the requirements for brushless motors also differ in various aspects. So, how to choose the appropriate brushless motor for model aircraft? Here are some tips! 
 

Knowledge of Model Aircraft Motors: 
1.For aircraft motors, brushless motors are typically used. These motors can control the alternating changes of different current directions within the motor. 
2. When choosing the motor for an aircraft model, the size of the stator should be taken into consideration. The size of the stator directly affects the power of the motor. The larger the size, the greater the power, and the heavier the weight. 
3. The number of slots and poles of the motor is directly proportional to the rotational speed. The fewer the number of slots and poles, the higher the rotational speed of the motor. The torque of the slots and poles is directly proportional. The larger the number of poles, the greater the torque. 
 

Selection of model aircraft motors: 
When choosing an aircraft model motor, the first step is to select the size and type of the motor based on the size and design requirements of the aircraft model. 
2. The appropriate number of KV is a factor influencing the balance of the wing aircraft. The torque will affect the output of the reducer. 
3. The KV value and voltage can be selected according to the reducer. The voltage is strictly proportional to the motor speed. KV x voltage x reduction ratio = actual speed. 
4. The KV value should not be too high. The larger the motor, the smaller the KV value should be. The current should be selected based on the motor model. The discharge coefficient multiplied by the capacity equals the battery discharge current. 
5. The brushless motors from different manufacturers and of different models all produce sine waves. 
6. The service life of the model aircraft motor is directly affected by the differences in the bearings. Even after speed adjustment, the service life will not be prolonged.
