What is the neutral point of an alternating current motor? How to determine whether the neutral point leads to?
There are mainly two kinds of motor connection, star connection and angle connection two kinds. - star connection is 3 at the end of the three-phase coil motor connected together as a common, common end is neutral.Angle connection -- is to each phase of the three-phase motor through the coil ends are orderly connected with the connection. ?????Three phase winding motor is completely into the end cover is connected, the end cover has six heads, three heads below together, the above three heads respectively leads to the three line is the star connection; the upper and lower two head vertical connection, respectively leads to the three line is connected with the triangle.
The AC motor only meets the three-phase fire line, the three-phase is balanced, the neutral point does not connect the zero line, also does not have the ground.
AC motor star connection, only the neutral point, as shown in the figure, the neutral point of the motor is connected with lead wire, 4 wire, three fire zero, zero line to neutral point.
