What is the difference between in-winding and out-winding of brushless motor stator?

Brushless motor stator needs to be wound, the coil is energized to produce a magnetic field, the motor can operate normally, the common stator winding is divided into two types, the stator inside winding and outside winding, then the stator inside winding and outside winding in the end what is the difference? The following is to introduce to you 

1. The direction of the slot of the stator differs depending on its winding method, the slot of the externally wound stator faces outward and the slot of the internally wound stator faces inward. Due to the different design and structure of the stator skeleton, you can choose the opening direction according to your needs.

2. The winding method is different. For the outer winding stator, the flying fork winding method is often used, the wire enters the slot from the outside, which is fast and efficient and is a more economical way to wind the stator, and the common stator can be wound in this way; for the inner winding stator, the needle winding method is often used, the slot of the stator is facing inward, the outside of the skeleton is closed, and the winding process is completed by moving the needle bar up and down, left and right, with the mold.

3. The inner winding of stator is suitable for motor stator products such as home appliances, medical devices, pumps, electric tools, etc.; the outer winding of stator is suitable for motor stator products such as model airplane, drone, camouflage gun, electric car, etc.
