Huangyang gt series Vector control vfd ? Whats the difference?

Hi Andrew

In theory with the vector control you have good constant speed and better torque at low speeds. In practice the vector control needs advanced electronics with fast microprocessor, etc. and I don't now how successful/reliable have the Chinese at Huanyang implemented it.

Hi Paulus

Thanks for reply. I might get one for my buffing machine which runs badly with a triac speed controller i'm using and the torque really drops off at lower speeds whe pushed hard.
Cheers
