Analysis of the Formula for Calculating Commutation Noise Frequency in Brushless Motors

This article provides a brief analysis of the formula for calculating commutation noise frequency in brushless motors. Brushless motors operate in six different states, denoted by 1 and 0, representing the direction of current flow in the three-phase winding—1 for positive and 0 for negative. Positive current flows from the first end to the last end of the winding, while negative current flows from the last end to the first end.
