Comparison Between Classic and Space Vector Models of the Induction Motor during Start Up at Industrial Frequency

Abstract:

A comparison between space vector and classic steady state models of the induction motor is performed during the start up condition at industrial full voltage and frequency. This work shows several imprecisions obtained when the impact over the system is analyzed using classic models, especially during the start up. Pulsating torque effects and magnitude of maximum torque are considered. A deep bars model of the squirrel cage motor in space vector coordinates was developed, and its parametric estimation is performed to match the motor data sheet and experimental results with the machine performance in transient behavior. The wound rotor machine is modeled in space vector coordinates, compared with the classic model and its parameters obtained by an estimation algorithm. Electric transient behavior, harmonic analysis, dynamics and source unbalances can be better analyzed using space vector …
