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.

The key is to create a torque using DC current in two phases while the third phase is not connected. As the rotor is moving, the phases are switched (commutated) to keep the stator flux ahead the rotor flux. Web3.2 Principles of six-step BLDC motor control The three-phase BLDC motor is operated in a two-phase model; that is, the two phases that produce the highest torque are energized while the third phase is off. Which two phases are energized depends on the rotor position. The energized phases change ev ery 60° (electrical de grees) as shown in ... over drinking and urinating low potassium
