Y connection of square-wave brushless motor, coil are two series of conduction - two

Y connection of square-wave brushless motor, the coil is two series of conduction, thus the motor input current should be equal to the motor phase current of each phase, brushless motor input & other; Standard & throughout; Direct current, the current effective value is equal to the average of the current, and through the controller after enter the brushless motor phase winding current waveform waveform should be a kind of communication, but definitely not a standard sine wave. Think of it this way: average should be equal to the input current, its effective value is determined according to the shape of the current waveform. So they are unequal.
