直线电机是指一种作直线运动的电机。早在1815年就有人提出原始直线电动机,但由于历史条件的限制,发展非常缓慢。到二十世纪初,英国、美国相继有人提出直线电动机用于铁路运输的建议,直到六十年代以来,直线电机在世界范围内才得到迅速发展。尤其是最近十几年来,直线电机已在国民经济的各个领域广泛应用,其中以高速地面运输和自动化领域尤为显著。原则上讲,对应每一种旋转电机都有相对应的直线电机,但从经济角度考虑,只有直线 Linear motor refers to a motor for linear motion. As early as 1815, some people proposed the original linear motor, but because of historical conditions, the development was very slow. By the early twentieth century, the United Kingdom and the United States have all along proposed that a linear motor be used for railway transportation. Until the 1960s, linear motors developed rapidly around the world. Especially in the last ten years, linear motors have been widely used in various fields of national economy, especially in the field of high-speed ground transportation and automation. In principle, there is a corresponding linear motor for each type of rotating machine, but for economic reasons, only the straight line
