摘要： There is disclosed a truck for use with a linear motor drive conveyor for conveying articles such as automotive bodies through a paint station. Shield means are provided carried by the reaction plate which in turn is carried by the truck. The shield means includes a central flat plate and downturned side edges which overlie and protect the gap between the reaction plate and the primary members of the linear motor from paint or other foreign particles.

摘要： In a linear motor comprising a moving body and a plurality of electromagnets arranged along the path of the moving body, the electromagnets are divided into blocks, each block comprising one or more electromagnets which are energized simultaneously. The blocks are energized sequentially with the time lag between energizations of sequentially energized blocks being sufficient to allow the current in each block to reach substantially its steady state level before the next block is energized. When starting the linear motor, a first block is energized, and a transient state occurs in which the current drawn by the first block is higher than the steady state current drawn by the first block. At the end of the transient state of the first block, a second block is energized. Third and fourth are energized similarly, each block being energized only when the transient state of the preceding block is substantially over, i.e. when the current drawn by the preceding block is substantially at its steady state level. The blocks are sequentially deenergized so that the total current drawn on the power supply is limited to the steady state current of two blocks plus the transient current of one block.

摘要翻译： 在包括移动体和沿着移动体的路径布置的多个电磁体的线性电动机中，电磁体被分成块，每个块包括同时被通电的一个或多个电磁体。 块被依次通电，顺序通电块的通电之间的时间间隔足以允许每个块中的电流在下一个块通电之前达到其稳定状态水平。 当启动线性电动机时，第一块被通电，并且发生瞬态，其中第一块所画出的电流高于由第一块所绘制的稳态电流。 在第一块的过渡状态结束时，第二块通电。 第三和第四通电类似地，仅当前一块的过渡状态基本上超过时，即当前一块所绘制的电流基本上处于其稳定状态电平时，每个块才被通电。 块被依次断电，使得在电源上吸取的总电流被限制为两个块的稳态电流加上一个块的瞬态电流。
