PURPOSE:To facilitate manufacture and management and reduce cost, by fixing stators with a fixing means coping with pertinent frequency among a plurality of the fixing means, according to the frequency of a power source exciting the stators. CONSTITUTION:A linear motor type track is composed of running rails 1 and a carrier 2a running on the rail 1, and as primary side cores provided with field generation coils between the running rails 1, stators 3a, 3b are fixed on a base plate 4a. The carrier 2a is composed of a container box 21, running wheels 22, a secondary side conductor plate 23a, slit plates 24, and a frame 25. In this case, spaces confronted with each other between the left and right stators 3a, 3b are set to be G1 when power frequency is of 50 Hz, and are set to be G2 when the power frequency is of 60 Hz, and the stators are screw- fixed on the base plate 4. The spaces G1, G2 are set so that the density of magnetic flux passing the secondary conductor plate 23a may be uniformed when the stators 3a, 3b are excited with respective frequencies, and running control is stabilized. |
