Air gap controlling system for linear motor |
摘要 |
<p>An air gap controlling system for a linear motor wherein a comparatively small air gap can be assured between a truck-carried element and a ground-mounted element to assure a high efficiency of the linear motor and construction for driving such ground-mounted element is simplified. Driving means is provided on each truck for driving a truck-carried element of a linear motor to be displaced upwardly or downwardly to adjust an air gap between the truck-carried element and an opposing ground-mounted element which also constitutes the linear motor, and an aimed value of the air gap between the two elements is set in response to a running speed of a velocity of the truck and a truck position signal representative of a position of the truck. At the first truck, the driving means is controlled so that the air gap may be equal to the air gap instruction value which is a rather high value. An air gap aimed value is set similarly for each of the trucks succeeding to the first truck, but is corrected so that an air gap of a succeeding truck may be controlled to a low value so as to assure a high efficiency of the linear motor. <IMAGE> <IMAGE></p> |
