现将在皮带机双机拖动设计中遇到的转子起动电阻计算问题介绍如下: 在实际应用中,当拖动电动机容量很大或是为了减少单个设备的重量和体积时,常采用双电动机拖动系统,即用两台电动机机械同轴并联运转的拖动方式。双电动机拖动可以由两个容量不同、转速不同的电动机组成,但一般常用的则为两个容量相同、型号相同的电动机组成。双电动机拖动系统的优点很多,如两台电动机的飞轮惯量将比相同功率的单一电动机拖动系统少20～30%;双感应电动机拖动系统调速
The problem of rotor starting resistance calculation encountered in the double dragging design of a belt conveyor will now be described as follows: In practical applications, when the capacity of the dragging motor is large or in order to reduce the weight and volume of a single device, a dual motor Drag the system, that is, with two motor mechanical coaxial parallel drive dragging. Two-motor drag can be two different capacity, different speed motor composition, but commonly used is the same capacity of two, the same type of motor composition. Dual motor drive system has many advantages, such as two motor flywheel inertia than the same power single motor drive system less 20 to 30%; dual induction motor drive system speed
