How to detect brushless motor hall is good or bad.
if there is a hall monitor, is very simple, directly into the joint of the hall hall on the detector, with his hand slowly rotating motor, three hall detector will, in turn, flashing lights, there are no flicker is broken. the multimeter can also detect, it is necessary to determine the hall has a + 5 v input signal, and then measured three line of the cathode voltage, when measured by hand, slowly rotating motor signal voltage will be between 0 v and + 5 v jump back and forth, the same is broken.
with multimeter + 20 v dc voltage, and the black pens and ground wire, red pens and measured voltage situation of three fuses, record the three fuses in the high and low voltage. Slight rotation motor, make motor turns a minimum Angle of magnetic force, once again, measure and record the 3 root lead high and low voltage, so measurement record 6 times. We use 1 high potential, represented by 0 means low potential, model aircraft motor, then & ndash; —If it is 60 & deg; Brushless motor, continuous rotation 6 minimum Angle of magnetic force, then measure the hall of true value signal should be: 100, 110, 111, 011, 001, 000. Adjust the three hall element lead pin order, let the true value of the true value of the signal in strict accordance with the above order is changed, so for 60 & deg; Brushless motor of A, B, C three phase is judgment came out. If it is 120 & deg; Brushless motor, continuous rotation 6 minimum Angle of magnetic force, measure the hall of the true signal should be in accordance with the 100, 110, 010, 011, 001, 101, the law of change, such a hall component lead power phase sequence is judgment came out
the hall electric motor line how to weld the
hall and motor line corresponding relation is how I know flipped the middle is 120 degree
the three hall and motor three-phase coil is associated, every hole is a set of guide line, coil hall induction motor regulated cycle, according to facies according to magnetic level signal to the controller provides to make a controller for each group of coil of the motor power supply make it work,
side hall component has the word up, plant protection unmanned aerial vehicle (uav) motor, from left to right to is; The positive, negative and signal lines, if it's 120 degrees, the installation will be three in the middle of the hall when a back up. black line is negative, the red line is positive, yellow, green and blue are signal output.
