还对锯机设计中主要性能参数驱动功率和锯片圆周线速度问题进行了较深入的讨论。
The saw cutting power and the circle line speed of saw web are also discussed.
由于电机转速很低，为了充分利用其圆周线速度，一般需要采用直径大而轴向长度短的结构，与传统高速电机的细长结构有很大区别。
The low speed machine usually has a short and fat structure in order to use effectively the rotating speed of the rotor, as contrasted with the long and thin structure of the high speed machine.
