Abstract:
Disclosed is a permanent magnet type motor. The permanent magnet type motor of the present invention includes a stator; a rotor which is separated from the stator; a rotor magnet part which comprises permanent magnets which are arranged along the circumference of the rotor; and a rotor position sensor which detects the position of the rotor by measuring the magnet field of the rotor magnet part. The protruding length of the permanent magnets on the rotor is different according to the position angle of the rotor.
Abstract:
A novel Pseudomonas fluorescens HYK0210-SK09 is provided to show excellent diatom growth inhibition effect capable of environment-friendly controlling the growth of the diatom against harmful diatom in fresh water, thereby effectively solving the green tide caused by the diatom in fresh water. The Pseudomonas fluorescens HYK0210-SK09 against harmful diatom such as Stephanodiscus hanzschii UTCC 267 in fresh water is deposited as a deposition number of KFCC-11368P. To control the diatom, the Pseudomonas fluorescens HYK0210-SK09 is applied to water system where the diatom occurs.
