Üç Fazlı Bir Asenkron Motorun Çeşitli Bobin Adım Biçimi ile Performans ve Harmonik Analizi
In this work, harmonic analysis of current and voltage waveforms, and investigation of efficiency, output power and torque characteristics of a three-phase, squirrel cage induction motor with full-, under-, and over-pitched stator windings under sinusoidal excitation are carried out. Performance analysis have been performed via Ansys/RMxprt software by modelling the stator winding with coil pitches of 100°, 120°, 140°, 160°, 180°, 200°, 220°, 240° and 260°. Current and voltage harmonics analysis have been performed in Matlab using the data obtained from Maxwell/2D simulations. Results showed that both under-pitched and over-pitched coils can be used to eliminate harmonics in the current and voltage waveforms. Under-pitched coils provide higher efficiency than the over-pitched coils. There is no unique coil pitch configuration to eliminate all harmonic components. Therefore, in order to eliminate a specific harmonic component, a specific coil-pitch must be applied.
