How to wind a brushless motor (number of windings per stator)

In summary, when determining the number of windings for a brushless motor, it is important to consider factors such as motor size, speed and torque requirements, and application type. The purpose of winding a brushless motor is to create electromagnets that interact with permanent magnets on the rotor to produce rotation. While it is possible to change the number of windings on a brushless motor, it is a complex process and should only be done by someone with experience. The optimal number of windings for a brushless motor will vary depending on the specific needs of the application. Using too many or too few windings can result in reduced motor performance and potential damage, so it is important to choose the appropriate number of windings for optimal motor

Hi folks,

I'm searching for information/procedure and also calculations/equations on how to correctly wind a stator on a (general or DC 3-phase) brushless motor? I.e. how to wind a copper wire X number of times around the stators, and thus get the desired performance/force that is required?

Thanks in advance!

Welcome to PF.
Can you please give a link to, or attach a picture of the stator.
How many poles on the rotor?
What RPM do you need?
What power?

1. How do I determine the number of windings per stator for a brushless motor?

The number of windings per stator for a brushless motor is determined by the motor's design and the desired performance. This information can usually be found in the motor's specifications or by consulting the manufacturer's guidelines.

2. What is the purpose of winding a brushless motor?

The purpose of winding a brushless motor is to create an electromagnetic field that interacts with the permanent magnets on the rotor, causing the motor to rotate. The number of windings per stator affects the strength and speed of this electromagnetic field and therefore, the motor's performance.

3. How does the number of windings per stator affect the motor's performance?

The number of windings per stator directly affects the motor's torque, speed, and efficiency. A higher number of windings will result in a stronger electromagnetic field, providing more torque and slower speeds. A lower number of windings will result in a weaker field, providing less torque and higher speeds.

4. Can I change the number of windings per stator to improve a motor's performance?

Yes, the number of windings per stator can be changed to alter a motor's performance. However, this should only be done with caution and according to the manufacturer's guidelines, as altering the number of windings can also affect the motor's durability and efficiency.

5. Are there any other factors to consider when winding a brushless motor?

In addition to the number of windings per stator, other factors such as the gauge of wire used, the type of winding pattern, and the quality of the winding can also affect a brushless motor's performance. It is important to carefully consider all of these factors when winding a motor to achieve optimal results.
