为了让电动伸缩门电机旋转时，控制模块必须首先根据由所述传感器所感测的马达转子的当前位置，然后根据该定子确定开口（或关闭）在所述逆变器的功率晶体管的顺序绕组。 AH，BH，CH（这些被称为上臂功率晶体管）和AL，BL，CL（这些被称为下臂的功率晶体管），使通过电动机线圈的电流的流动，以产生一正向（或反向）旋转磁场，并将其与转子的磁体相互作用，使得电动机可以正转/反转。当电机转子转动到一个其中所述传感器感测的另一组信号的位置时，控制模块接通的下一组功率晶体管。

在这个循环中，电动伸缩门电机可继续旋转在相同的方向，直到控制模块决定停止马达。关闭电源晶体管（或仅打开所述下臂功率晶体管）。如果在反方向的马达旋转时，功率晶体管导通以相反的顺序。

In order for the electric retractable gate motor to rotate, the control module must first determine the sequence winding of the opening (or closing) in the inverter power transistor according to the current position of the motor rotor sensed by the sensor, and then according to the stator. AH, BH, CH (these are called upper arm power transistors) and AL, BL, CL (these are called lower arm power transistors) make the flow of current through the motor coil to generate a forward (or reverse) rotating magnetic field and interact it with the rotor magnet so that the motor can be turned forward/reverse. When the motor rotor rotates to a position where the sensor senses another set of signals, the control module switches on the next set of power transistors.

In this cycle, the electric retractable door motor can continue to rotate in the same direction until the control module decides to stop the motor. Turn off the power transistor (or turn on only the lower arm power transistor). If the motor rotates in the opposite direction, the power transistors are switched on in the reverse order.
