近几年来,在群众性的技术革新和技术改造运动中,国内不少单位开始研制和应用一种新型的电力传动装置——直线电动机。直线电动机是一种特殊的电机,接通电源后,能直接作直线运动。它是一种将电能直接转变成直线机械运动,而无需中间传动 In recent years, in the masses of technological innovation and technological transformation of the movement, many domestic units began to develop and apply a new type of power transmission - linear motor. Linear motor is a special type of motor, the power directly after the linear motion. It is a direct conversion of electrical energy into linear mechanical motion without the need for an intermediate transmission
