This paper introduce faults diagnosis based on current analysis. The current spectrum of a
three phases and single phase induction motor and also of a DC motor, are analyzed in …

To improve the fault diagnosis accuracy of the broken rotor bar (BRB) of the squirrel-cage
induction motor, a novel fault diagnosis method of the BRB based on the adaptive notch filter …

Direct current motors (DC motor) are used in the small electric devices commonly. Brushed
DC motors are cheap and easy to install, thus their popularity. Although the popularity, faults …

Power rectifiersare important devices for AC to DC conversion. Many systems are supplied
through this electronic powerdevice. These systems include DC electric motors, exciter …

Single-phase permanent-capacitor induction motor is studied in this paper using a model
based on inductances calculated by finite elements method (FEM). The effects of rotor …
