This paper presents novel active filter for mitigation electromagnetic interference (EMI) and other adverse effects of pulse width modulation (PWM) inverter-fed AC motor system. An active filter proposed and devised for this system is characterized by sophisticated connection of two small separate filters, capable of mitigating all the adverse effects. This paper provides high frequency models ...

Bearing is a component that affects the performance of a rotating machine in order to be used properly. The purpose of using ball bearing is to reduce rotational friction and support radial and axial loads. Diagnosis of bearing vibration data is an important process to identify either the bearing is normal or defect. In this paper, we consider a single bearing system that consists of one normal...
