Analysis of axial voltages and inter-bar currents in cast copper cage rotors during DC current injection as an aid to identify casting faults

Dorrell David; Frosini Lucia; Bottani Marcello; Galbiati Giacomo; Hsieh Min-Fu (IEEE, 2009)

In this paper an investigation is carried out to see if it is possible to assess the condition of a rotor by clamping it in a DC-current-injection rig and measuring voltages in bars at regular intervals down the axial ...
Calculation of starting torque in skewed-rotor cage induction motor with broken bar and rotor eccentricity using hybrid analytical/finite element analysis technique

Dorrell David; Frosini Lucia; Bottani Marcello; Galbiati Giacomo (IEEE, 2009)

This paper addresses the variation of starting torque in a 3-phase induction motor. It presents some example results from an experimental investigation then develops a hybrid analytical/finite element method for rapid ...
Starting torque analysis in skewed-cage induction motor with broken bar using a combined hybrid analytical/finite element technique

Dorrell David; Frosini Lucia; Bottani Marcello; Galbiati Giacomo (IEEE, 2009)

The aim of this paper is to analyze the positional variation of starting torque in a 3-phase induction motor. This can depend on different factors: manufacture of the rotor (fabricated or cast), skewing of the rotor bars, ...
