Brushless motor controller of two kinds of speed measurement brushless motor controller to the current support of simple structure and single, in numerous motor controller products running speed of first-class, their knowledge of velocity measurement is introduced as follows, hope you read them. 1, the principle of hall effect speed measuring method of brushless motor controller of magnetic steel shaft drive shaft rotation, the size, changing magnetic field by hall circuit converts magnetic field changes to the pulse signal, cosmetic enlargement, rectangular pulse signal output. When the speed changes, the output pulse frequency can change. Dc gear motor controller rotational speed is obtained. 2, photoelectric speed measuring method of using grid disk and optical switch speed measuring system. When the brushless motor controller through the transmission part of the grid disk rotates, the speed photoelectric door to obtain a series of pulse signal. The pulse signal by single chip microcomputer with two timer/counter, a count a timing. Calculate the number of pulses per unit time m, through unit conversion, you can calculate the motor rotation speed controller. More knowledge introduction over, want to know more information dynamic brushless motor controller, focusing on our dynamic, or to inquire, we are looking forward to your attention!
