本文介绍了在煤炭生产中研制直线电机推车的过程,其中对设计要求、方案比较、测定数据、电机参数等方面进行了较详细的叙述。初步实践表明,直线电机驱动的推车机,是一种比较理想的推车机构,为存在大量往复运动的煤炭生产开辟了广阔的发展前景。 This paper introduces the process of developing linear motor carts in coal production. The design requirements, program comparison, measurement data and motor parameters are described in more detail. Preliminary practice shows that the linear motor-driven cart is an ideal cart mechanism, which opens up a broad prospect for the coal production with a large number of reciprocating motions.
