BALANCING ECCENRTIC ROTOR OF SYNCHRONOUS MOTOR

The relevance of the study is due to widespread use turbomechanisms (pumps, fans, compressors) in various industries. For electric drives these mechanisms, urgent task increase speed rotation motors. This associated with an productivity turbomechanisms, which affects volume production products. However, commercially available AC motors at network frequency 50 Hz have rotational speeds no more than 3000 rpm. In order obtain twice speed, a synchronous motor six-phase stator winding and jet rotor was designed. When powered by general industrial three-phase Hz, it has 6000 eccentric design rotor, shaft significant beats caused pendulum moment. These runouts can lead destruction bearing premature failure motor.
 
 purpose analyze ways balancing high-speed Materials methods. Analytical methods theoretical mechanics theory electromechanical energy conversion were used work. mechanical calculation performed using Compass 3D program.
 main results are picture moments arising from eccentricity analysis compensate for moment imbalance rotor. It established that dependence on angle harmonic function. Therefore, imbalance, necessary create varies antiphase shown most rational eccentrics compensation additional electromagnetic created help magnetic field. Based comparative effectiveness methods, their advantages disadvantages shown. principle compensating considered.
