Like many of you, when we first heard that the new QuietDrive controller for Ecotech Marine Vortech pumps resulted in 90% less noise, we simply couldn’t believe it. We could fathom how better motors, high tech bearings, and other engineering refinements could reduce motor noise by a little, but what voodoo-talk is Ecotech Marine trying to get by us with the idea that ‘programming’ alone can result in such a stealthy yet powerful water pump?
Then we had the opportunity to see new and old Vortechs alike, the MP10, MP60 and MP40 all being powered with the new QuietDrive controller. The pairing of all Vortech models results in these pumps being几乎as quiet as a pump which isn’t even plugged in. If we were on the other side of this screen and reading this we would be just as incredulous as you but the result simply has to be (un)heard to be believed.
The way thatdirect currentDC电动机的动力是通过一系列非常快速的电脉冲系列，这些电脉冲针对设备的频率和功率需求进行了调整。想象一下，一个人会尽可能快地推动旋转木马 - 拆除推动力的那一刻，旋转木马开始放慢速度，直到下一次推动。在DC电动机（例如为Vortech泵送的动力的电动机）中，这种推动的发生得非常快，但是每次推动之间的速度变化才会产生可听见的噪声。
Through extensive testing, calculations, and lots of trial and error, Ecotech Marine’s QuietDrive has created the electronic equivalent of having lots of people around the merry-go-round, such that there is nearly always a force being applied to the playground ride. By creating a controlled electrical signal that keeps the motor rotating within a much narrower range of speed, the motor runs so smoothly that it results in more flow, greater efficiency, and most importantly, an incredibly quiet water mover.
