M5 CW CCW Propeller Fixed Adapter Nut Cap For Brushless DC Motor

The M5 CW CCW Propeller Fixed Adapter Nut Cap set includes two different nut caps, one for CW (clockwise) and one for CCW (counterclockwise) rotation, designed to be fitted above the propeller on brushless DC motors. These nut caps often come in different colors, such as black and silver, to enhance user-friendliness.

Understanding the distinction between CW and CCW motors is crucial, especially in the context of quadcopter building. Despite being essentially the same motors, CW and CCW motors differ in the direction of their prop shaft threads. For instance, a CCW motor has prop shaft threads that tighten clockwise, while for a CW motor, the threads tighten anti-clockwise.

The key advantage of having different threads for CW and CCW motors is referred to as ‘Self-locking.’ In a quadcopter setup where two motors spin clockwise and two spin counterclockwise, using threads opposite to the motor spin direction ensures that the prop nuts automatically lock themselves down, preventing them from coming loose during flight.

However, this design choice can lead to challenges in sourcing spare prop nuts for both threads and can cause confusion when determining which way to turn to remove the prop nuts during propeller changes.

In practical terms, if you can fasten the prop nut clockwise, you have a CCW motor, and you should use the Right-handed thread nut (standard thread). For CW motors, opt for the Left-hand thread nuts (reverse thread).

While this setup may introduce some complexity, it provides the benefit of self-locking prop nuts, ensuring a more secure and reliable connection during quadcopter operation.
