Connect electric normal . Is this why ?

1 phase angle may be wrong. Song is the degree of control is not written above 120 degrees , write degrees is 60 degrees.
2 Santroll matching controller is not very strong , especially rare motors on the market , so for another just fine with .
3 may be a phase when you start wiring wrong, jitter weakness and other phenomena, who rode to put the controller burned , so you do not turn up later then how can you be sure that the Battery powered bikes controller burned. Before wiring , the first to detect motor Hall is good or bad , angle, winding and magnet motor is normal, then use the accompanying controllers, such as voltage , current limiting , angle , phase , etc. The key is to be consistent with the angle of the motor controller , otherwise they might forever . Motor angle detecting very simple , as long as there are three high three Hall signal is low, that is 60 degrees, the controller detects an angle relatively quickly and accurately with the instrument . After the above work , electrical wiring 60 degrees within 10 minutes and 120 degrees within one minute to get the motor . 27 , and the line on the color phase motor problems on the green on the motor , blue, yellow, in the end what is the Three wheel bikes representative of each phase ? Some places to see A, B, C phase , and sometimes see is W, V, U -phase ? Most standard A, B, C phase is represented by what color , with green, blue , yellow, how correspondence ? There are green, blue , yellow, three -phase line controller coarse , sometimes with 3 phase motor is completely linked by color , simply can not be transferred , and why ? Many plant previously used this provision : A- Yellow , B- Blue , C- Green . Latest national standard " electric bicycle motors and controllers" ( draft) 4.6.1 states: motor terminal A- blue , B- Green , C- yellow. Hall outlet color requirements with the motor. A --- U, B --- V, W --- C motor factory in order to do some changes in the electrical outlet different colors, with matching controllers for each manufacturer had to change the way the outlet . 28 , brushless controller detects stall current, battery cathode series digital multimeters, clamp meter Cece any other motor with a thread , both the current reading is inconsistent, digital clamp meter multimeter relatively large in terms of many , why ? Power input current to prevail . Motor current is pulsating , not easy to measure accurately , in addition to
