| Detection, brushless motor: 1, motor Holzer quality detection: The detector six hole socket connected well tested motor Holzer line hole plug (five string, motor colours are red, black, yellow, green, blue), in addition to the Rossoneri must be properly connected to other can be connected, turn on the power switch, slowly along the forward direction rotating electric motor, can see second rows of three Ha, Hb, Hc, LED indicator ordered light out, such as one or more non ordered light out, that Holzer has been damaged, if three LED light does not change, is red, black line circuit breaker or Holzer has been damaged (red, black line voltage is lower than 4.5V, second rows of three LED will shimmer not change please get a new battery and then measured, batteries do not pack of three). 2, motor Holzer phase detection The detector six hole socket connected well tested motor Holzer line hole plug, red, black must be properly connected, turn on the power switch, slowly along the direction of rotation of motor vehicle in 6 position, by adjusting the motor Holzer blue, green, yellow lines and detector are matched, the second rows of Ha, Hb, Hc the LED indicator light, does not conform to table A, B, C, D, E, F six stable state changes and recurring.
The "1" represents the lights bright "0" the lights go out Corresponding to the motor Holzer line Tin Plug docking repair treasure on the blue line Ha (Holzer a) green line corresponding to Hb (Holzer b), yellow line corresponding LED Hc (Holzer C), if the connection to adjust the blue green yellow wire and car Bao, third rows of LED indicator changes consistent with table 1 change, now remember motor three Holzer lines corresponding car Bao blue (Ha), green (Hb), yellow (Hc) three line color sequence, we can motor Holzer line, B, a C sequence. 3, the motor phase angle detection Table 1 shows 60 o motor with "111", "000" two states, and 120 o motor is not, only "010", "101" two kinds of state, so the brushless motor test three LED indicator appears bright, and destroy the motor is 60 o, otherwise 120 o motor. 4, the motor winding: Take any two motor three thick line in three of two two short circuit, electromagnetic resistance slide motor should be uniform, no blocking phenomenon, two two open, positive inversion should also be no blocking, the motor winding open circuit or short circuit phenomenon does not exist, such as after disconnect reversing all electromagnetic resistance judge for the winding short circuit, determine the motor by detecting motor Holzer detection and motor winding can be good or bad. Detection of two, brushless controller: Detection of brushless controller without opening the instrument power supply switch belongs to a vehicle detection method, based on detection of motor case only to the original electric vehicle controller, rough, coarse coarse blue green yellow 3 main phase and brushless motor three thick line was torn off, and then the controller coarse blue, green, yellow three main coarse coarse phase respectively and the instrument three blue, green, yellow bullet or alligator clip is connected with the connecting line, electric vehicle controller power, in the confirmation to the well under the circumstances to turn the rotation to the maximum position, and then slowly shifting motor rear wheel, and the first row of controller corresponding color KA (blue), KB (green) KC (yellow) three luminous tubes should be ordered alternating light, extinguishes, brightness and turn the rotary angle, the controller without fault. On the contrary, there is one or a few LED light or long arc does not change, indicating that this controller has been damaged. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
