LINEAR MOTOR

摘要

PROBLEM TO BE SOLVED: To provide inexpensively a linear motor having small magnetic loss and good volume efficiency. SOLUTION: A cylindrical outer yoke 3 comprising the outer yoke section 1 is provided with 8 columns of equidistant through-holes 3a placed circumferentially. A winding 4a and a winding 4a wound separately in two sections are secured on the surface of the inner perimeter of each through-hole 3a and contained in a holding frame 8. The inner yoke section 2 is provided with 8 inner yokes 5, each penetrating a through-hole 3a of the outer yoke 3 and having each end integrated with a connecting plate 7. An axis 7a of the connection plate 7 is supported by a sleeve 9a of the side plate 9 installed on the opening at each end of the holding frame 8 to allow relative movement. COPYRIGHT: (C)2003,JPO
