─ This paper presents an equivalent circuit derived directly from Maxwell's equations in a manner to show the amalgamation of field models and the circuit theory. A micro-T equivalent circuit is obtained from the solution of Maxwell’s equations for a cylindrical representation of a squirrel cage induction motor. First, a general form of the field solution is obtained using transfer matrices. A ...

This paper deals with detection and diagnosis of Stator Inter turn fault of three phase Induction motor. The proposed method is based on the stator current Clarke vector pattern. Three phase stator currents are used to construct Clarke vector pattern in order to distinguish the “healthy” and “faulty” condition of induction motor. The covered area for each pattern is calculated and the per unit ...

This article deals with standstill identification of an induction motor drive for sensorless self-commissioning purposes. The proposed method is based on advanced model a squirrel-cage motor. includes the deep-bar effect and magnetic saturation characteristics. excitation signals are fed to stator using standard inverter without compensating its nonlinearities. saturable inductance first identi...

In many industrial applications the self-starting capability of electric motors is still an important requirement enabling to simplify drive architecture and increase system's reliability. The efficiency improvement this motor topology has been targeted by various national international regulatory authorities with ad-hoc policies. Indeed, a lower energy consumption leads twofold benefits reduci...
