多台电动机起动控制电路设计

大中型电动机起动电流大 ,会引起电源电压降低影响附近其他设备正常工作。多台小型电动机在同时起动时也会引起上述结果。多数大中型电动机会采用降压起动技术。介绍了一种多台小型电动机直接起动控制电路 ,主要进行分时起动 ,电路联线简单、成本较低

The Design of Multi-electromotor Starting Control Circuit

The starting electric current of large-sized electro-motor and medium-sized electromotor is big,It will influence other equipments which are working normally nearby by dropping power source voltage down.The groups of miniature electromotors will have such affection if they start at the same time.The paper introduces a starting circuit to control miniature electromotors,the main technique is time-sharing starting,and this circuit is simple?lower costing.
