If starting torque is not an issue in the installation, the start delta orsoft starterare both OK. If you want to limit current rush in start or jam situation or you want to get higher starting torque then vector controlVFD is a good selectionand even better if closed loop with speed fe...
4.Operation performance is reasonable, the average torque and abrasion on the shaft is reduced because of the decline for average speed in one day, the life of pump will be longer. 5.Because it can realize the soft stop and soft start of water pump...
What we looking for are long-term partners instead of one-time business, so we will provide you high quality goods and do our best to provide you the best service Q12. How can I trust you ? A: CHEEGON ELECTRIC has 16 years' experience in producing soft starter, we have passed...
The two main features of variable frequency drive are adjustable speeds and soft start/stop capabilities. These two features make VFD’s a powerful controller to control the AC motors. VFD consists of mainly four sections; those are rectifier, intermediate DC link, inverter, and controlling circuit...
6. 积热电驿选用: 积热电驿选用须基于其过载能力,C2000 标准的制动能力为 10%ED(Tripping time=10s),故如下图所示的积热电驿, 其可承受260% 的过载10s(Hot starting),以460V110kw 为例,其煞车电流为126A,故可选用额定50A 的积热电驿。 由于积热电驿的能力不同,故选用时请参考制造商所提供之性能表...
