In this paper, the authors proposed to improve the efficiency of a rotary electric machine by employing a directional silicon steel plate having high magnetic flux density and low iron core loss as iron core material and laminating so that the directivity of the steel plate is uniformly dispersed as the entire iron core.Abstract:
PURPOSE:To improve the efficiency of a rotary electric machine by employing a directional silicon steel plate having high magnetic flux density and low iron core loss as iron core material and laminating so that the directivity of the steel plate, namely, the rolling direction is uniformly dispersed as the entire iron core. CONSTITUTION:A number sheets of pressed iron cores 1 are laminated in a manner aligning marks 2 are displaced at every several sheets. When the cores are thus laminated and fixed, their directivity becomes uniform as the entire core. This iron core material exhibits high magnetic flux density and low iron core loss of directional silicon steel plate as compared with the amorphous silicon steel plate to thus improve the using efficiency of a motor.read more
