| Summary: | The article discusses the scheme of inclusion of three-phase
induction motor to single-phase electrical network. The scheme
provides a symmetrical three-phase voltage system on the stator
winding. The purpose of the study is to determine the laws of changing the currents of two reactive elements that provide voltage
symmetry depending on the slip of the asynchronous motor. The
article presents the calculation expressions for determining the
conductivity of reactive elements on the known parameters of the
electric machine. As a result of the calculation, it is determined
that the current of one reactive element should have a capacitive
character in the entire range of the slip of the induction motor, the
other-capacitive or inductive. |
