トランス機能を持ったモータの基礎検討

抄録

In a motor with transformer function (MTF), where a magnetic core is used jointly as a motor core and a transformer core, the interactions between motor action and transformer one are investigeted in noload conditions. If flux densities are not saturated and magnetic circuits are balanced in the magnetic core, the characteristics of motor actions and those of transformer actions are almost independent each other. In motor actions, torques and iron losses are almost constant at frequencies different from transformer frequency, although they fluctuate at the same frequency. In transformer actions, exciting currents and iron losses increase although the increases are small at frequencies different from motor frequency. Thus a MTF drives almost individuals as a motor and a transformer in the same time.
