Vďaka odlišnému spôsobu spätného chodu je motor a bezkomutátorový motor nielen odlišná vnútorná štruktúra, ale aj rozdiel v režime pripojenia je veľmi veľký.
1, spôsob zapojenia motora kefy. Plus alebo mínus dve poistky motora kefy. Vo všeobecnosti pozitívne, červená čiara je motor, čierna čiara je katódový stroj. Ak máte záporné výmenné pripojenie, môžete len obrátiť motor, vo všeobecnosti nepoškoďte motor.
2, bezkomutátorová fáza motora Uhol úsudku. Fáza bezkomutátorového motora Angle je skratka pre fázu bezkomutátorového motora Uhol algebry, bezkomutátorový motor každej cievky v napájacom cykle vo vnútri hľadiska zmeny smeru prúdu cievky. Elektromotor bezkomutátorový motor bežná algebra fáza Uhol 120 & deg; S 60 & deg; Dva druhy.
priestor na inštaláciu jednotky v hodinovej hale odhadnutie fázy bezkomutátorového motora Uhol & 120 stupňov; A 60 & deg; Priestor na inštaláciu dvojfázových motorových halových jednotiek.
meranie signálu hala skutočná hodnota úsudok fázy bezkomutátorového motora Uhol
treba vysvetliť, čo sa nazýva bezkomutátorový motor magnetický ťah Uhol. Počet magnetov bezkomutátorového motora je vo všeobecnosti 12, 16 alebo 18 kusov, jeho zodpovedajúce číslo statorovej štrbiny je 36, 48 štrbiny alebo 54. Motor v stacionárnom stave, siločiary magnetického poľa rotora kráčajú pozdĺž minimálnej funkcie smeru magnetického odporu, takže umiestnenie magnetu rotora je pauza len pre polohu vyčnievajúceho pólu statorovej štrbiny. Magnetická oceľ sa nezastavuje v polohe srdca štrbiny statora, takže vzájomná poloha rotora a statora je len 36, 48 druhov alebo 54 druhov z obmedzeného počtu polôh. Takže najmenší uhol magnetického ťahu bezkomutátorového motora je 360/36 & deg; 360/48° Alebo 360/54 & deg; 。
bezkomutátorová motorová halová jednotka 5 koreňových poistiek, resp. halový prvok verejnej energie, verejná li-ion hala, výstup fázy A, výstupná fáza B hala a výstup fázy C. We can take advantage of the brushless controller (60°Or 120 & deg; ）5 root hall fuses, brushless motor hall element of positive and negative power connected and the lead to the rest of the A, B, C three phase sensor lead, any meet in the hall signals to the leads of the terminal controller. Turn on the controller power supply, by the controller to power a hall element, can detect the brushless motor phase Angle. Method is as follows: the multimeter + 20 v dc voltage blocking,
electric motor
and the electric motor 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, so & 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 electricity phase sequence is judgment came out.
if you want to quickly detect brushless motor is 60 & deg; Or 120 & deg; , use multimeter + 20 v dc voltage, and the black pens and ground wire, red pens and the voltage measured three leads, and in three lines have voltage or determine when no voltage is 60 & deg; Motor, otherwise it is 120 & deg;
3, brushless motor wiring method. Brushless motor coil fuses three root, hall 5 root, lead the eight root must lead and controller corresponding leads one to one correspondence, or machine can't normal rotation.
tell commonly, 60 & deg; And 120 & deg; Phase Angle of the brushless motor, and at the same time has to be 60 & deg; And 120 & deg; Phase Angle of the brushless motor controller to drive, two phase Angle controller cannot direct swaps. 60°Phase Angle of the brushless motor with 60 & deg; 8 lines phase Angle controller is connected to the correct connection of two kinds, a kind of forward, a kind of inversion.
for 120 & deg; Phase Angle of the brushless motor, by adjusting the phase sequence and hall coil lead wire of the phase sequence, motor 8 lines connected to the controller of correct connection can have six, three kinds of connection motor forward, three kinds of connection motor reversal.
if the inversion of brushless motor, brushless controller and brushless motor phase Angle is match, we can turn this motor to adjust the: brushless motors and brushless controller hall leads A and C exchange connection; At the same time the brushless motor and brushless controller of main line A and B exchange connection.
electric bicycle generally can be divided into three kinds. 1, dc motor, and both the motor, the two lead, external PWM controller. 2, the ac wheel motors, with and without hall of hall sensor, more than three lead, an external variable frequency controller. 3, dc brushless hub motors, containing electronic commutator, two lead. External PWM controller. Be sure to distinguish, not to be confused.
