WebAug 5, 2024 · Trapezoidal commutation is also known as “Six Step Commutation” because there are total six steps of drive current used to complete one revolution of rotor. In trapezoidal control at a time only two phase are active. This method has simple control algorithm but the torque ripple exist in the motor at every commutation (60 Degree). … WebBLDC motors with non-sinusoidal winding distribution generate trapezoidal back-EMF, as shown in Figure 3. Trapezoidal Back-EMF BLDC motors are specifically designed to be driven with square voltages synchro- nized with the motor’s angular position. This control method is commonly called six-step commutation.
