Patent number: 7965009Abstract: A motor rotor has a resin-impregnated thread layer formed by winding a thread of a reinforced fiber material around a permanent magnet layer with a gap between an outer peripheral surface of the thread layer and an inner peripheral surface of a cylindrical body, and impregnating the thread layer with a curable resin. A subsequent thread layer is formed by leading a continuous thread into an annular passage through thread passing recesses, winding the continuous thread around a bottom portion of the passage, and impregnating the subsequent thread layer with a curable resin. A curable resin is injected into the gap between the outer peripheral surfaces of the thread layer and the subsequent thread layer and the inner peripheral surface of the cylindrical body through resin injection passages and/or the thread passing recesses before heating and curing.Type: GrantFiled: October 16, 2007Date of Patent: June 21, 2011Assignee: Sanyo Denki Co., Ltd.Inventors: Toshihito Miyashita, Takashi Matsushita, Norihito Tanaka
