Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Study of transition processes in the induction motor with asymmetries in chains of three-phase rotor on instant value of the variable D.K. KOKHREIDZE An analytical study of electromagnetic transients in a three-phase asynchronous motor is carried out when one phase of the rotor winding is broken. The equations of an asymmetric mode on instantaneous values in phase coordinates are transformed in complex quantities. Operational images of the complex values of the stator and rotor currents in Carson-Heaviside are obtained. Complex currents are defined as a function of time, as well as instantaneous phase currents of the stator and rotor. The expression for the electromagnetic moment of the motor is obtained. Keywords: induction motor, the current complex, asymmetrical mode, the electromagnetic torque. DOI: 10.25791/pribor.08.2018.134 Contacts: E-mail: dKokhreidze@mail.ru Pp. 27-32.
