20090195201 | METHOD FOR CONTROLLING AN AC ELECTRONIC MOTOR AND DEVICE FOR CARRYING OUT SAID METHOD - The invention relates to electric engineering, in particular to methods for controlling an ac electronic motor. The inventive control method consists in starting and rotating a rotor upon EMF signals in current-free sections of an armature winding, in converting the EMF signals into discrete logical level signals by a normaliser, in detecting switching points by means of a microcontroller and in displacing said points according to a load current quantity, the rotor speed of rotation and the inductance of the armature winding sections, wherein the switching points are calculated and displaced with respect to bridging times of the free sections EMF whose voltage levels are different from zero. The inventive device is characterised in that it comprises a reference level displacing unit ( | 08-06-2009 |

20130186638 | LINEAR ELECTRIC MOTOR FOR ARTIFICIAL LIFT SYSTEM - A method for pumping production fluid from a wellbore includes deploying a downhole assembly of an artificial lift system (ALS) into the wellbore. The downhole assembly includes a linear electric motor (LEM) and a pump. The method further includes operating the LEM, thereby reciprocating the pump and lifting production fluid from the wellbore to surface. The LEM includes a stator and a reciprocating head having permanent magnets. The production fluid leaks through an interface formed between the head and the stator. | 07-25-2013 |

20140313508 | METHOD FOR THE EMISSION ANALYSIS OF THE ELEMENTAL COMPOSITION OF LIQUID MEDIA - The proposed method is related to the field of technical physics, in particular, to spectral methods for determining elemental composition of liquid media using an electric discharge in the liquid as a source of spectra. The method can be implemented in devices for determining elemental composition of liquid media. The areas of application include water treatment systems at public water supply facilities, nuclear and thermal power industries, chemical industry, food industry processes (for water quality control), environment monitoring, etc. The technical result of the invention is higher stability and reproducibility of measurement results and better long-term operation reliability of the device. The proposed method for emission analysis of elemental composition of liquid media includes initiation of a local electric discharge in the liquid under analysis with the formation of a current-carrying channel in the volume of a diaphragm opening made in a member of the electrolytic cell structure, and detection of the generated emission spectra of the chemical elements being determined. | 10-23-2014 |
