Despite the great potential and high performance of energy-efficient line-start permanent magnet synchronous motors (LSPMSMs), their developers face a deal difficulties, one which is lack reliable accurate testing methods for such electrical machines. In this paper, we propose new method indirectly determining efficiency LSPMSM through summation individual loss components. The standard input-ou...

An increase in reactive power consumption results an electricity costs. This negative phenomenon can be prevented by using compensation methods. One of them is the installation capacitors. These capacitors are exposed to external conditions, such as temperature and humidity. As a consequence, aging process occurs. Another corrosion that occurs inside capacitor result moisture absorption. this p...
