IPC: H02K29/00
Filed: 1988-08-10
Abstract: PURPOSE:To prevent vibration of a yoke by composing at least one rotor of an alloy where iron flakes are mixed with aluminum. CONSTITUTION:A rotor yoke 33 is composed of an alloy where iron flakes are mixed with aluminum molten, for example. Iron is mixed by 40-90vol.%, preferably 60-70vol.%.
