卷取机张力调节系统过去多为电流电势调节系统,它有几个主要缺点: 1.由于磁通φ正比于带卷直径D的变化,除了在卷径最大时外,卷筒电动机经常在弱磁下工作,力矩不能充分发挥。卷筒电动机的加速和减速受到换向能力的限制。
There are several major drawbacks with coiler tension control systems that used to be current potential regulation systems: 1. Because the flux φ is proportional to the change in the coil diameter D, the reeling motor is often weak except at the maximum coil diameter Magnetic work, torque can not give full play. The acceleration and deceleration of the reel motor are limited by the ability to change over.
