Bldc hall sensor waveform
WebFeb 24, 2013 · As the phase current is trapezoidal, we call 6-step BLDC control trapezoidal control. The Hall sensor and the excitation have a fixed relationship. Typically, there are two types of Hall sensors. For the first type, for each HALL phase, their waveforms have a 60-degree time-lapse. For the second type, the waveform time-lapse is 120 degrees. WebTechniques which do not use Hall sensors should be used then. This paper deals with the analysis of hardware and software aspects during the development of such a microcontroller based and low cost speed controller for motors up to 500 W, along with its practical implementation. ... The waveform of the back-EMF difference is shown in Figure 2a ...
