查询词典 high speed

The key points of sensorless technology in PMBLDCM are to study a method which can detect rotor position accurately by simply method in whole speed range. After analyzing current sensorless methods of the PMBLDCM, it is found that those methods are successful at middle and high speed, but they often fail to detect rotor position at low speed when the back electromotive force is small or zero.

The result shows that, when a free droplet transfer mode is applied in high-speed welding , the workpiece is heated by the arc throughout the process and thus the molten pool can not solidify in time.As a result, the molten pool is very long, which gives way to the instability of bead formareron and pinch effect of the liquid metal,so that it finally leads to the humping phenomenon. Based on the analysis and experimental result, the short-circuiting transfer mode is suggested to improve the bead formation in high-speed welding .
