Title: Linear induction motor
Inventor: SAITO YOICHI
IPC: H02K41/025
Filed: 1999-10-01
Abstract: PROBLEM TO BE SOLVED: To provide a linear induction motor having secondary conductors of easy-to-manufacture ladder structure in which thrust operation can be carried out smoothly. SOLUTION: A back yoke having protrusions 10a and a stator unit 8 of ladder structure having secondary conductors 11 arranged perpendicularly to the traveling direction are formed in the same shape as a grating unit and laid on the traveling passage of a carrying vehicle. Primary core 5 of the carrying vehicle traveling in the direction of a guide groove 12 is fixed while inclining against the traveling direction by a skew angle from perpendicularity. When the primary core 5 is conducted, eddy currents are induced in the secondary conductors 11 to generate a thrust for traveling the carrying vehicle. Since the primary core 5 is inclining by a skew angle, fluctuation in the quantity of flux passing through the protrusions 10a and fluctuation of thrust are suppressed to ensure smooth traveling of the carrying vehicle.  Furthermore, manufacture of a stator unit 8 can be facilitated because the ladder structure of the secondary conductors 11 is in parallel with the end face of the stator unit 8.
