PROJECTS IMPLEMENTED IN THE FIELD OF ELECTRO-MECHANICAL DRIVE IN 2020
Electro-Mechanical Drive personnel work with the entire segment of motors and their control and launch systems. These include those requiring unusual complicated applications.
For over 10 years, DEMP has cooperated with the WEG company (Brazil), one of the world’s largest producers of electric machines offering motors in different versions and applications from low-voltage to high-voltage, with practically no limitation on output.
In 2019, Sever Minerals started cooperating with VEM, Leroy-Somer, SEC, Nidec, Siemens etc.; in 2020 its EMP specialists extended the product range offered by the division. It now includes:
· liquid starter rheostats from manufacturer MKS, used to start asynchronous motors with a phase-wound rotor;
· Nidec reacting power compensating devices for the medium voltage.
The Electro-Mechanical Drive personnel implemented several large projects in 2020:
A process gas compressor motor had been replaced in hot briquetted iron Shop 3. The engineers of Sever Minerals suggested a more reliable explosion proof WEG MGF Ex motor with a capacity of 8.6 kW equipped with friction bearings. The motor was designed with due account of all features and objectives of the enterprise. The dimensions of equipment allowed its installation in place of the previous motor with minimum modifications of the shop’s interior space. All control signals of the control and measurement instruments and attachments were coordinated during the development. The motor uses less electrical energy, and the friction bearings serve for not less than 30 years with no replacement required. The equipment fully complies with the enterprise’s requirements.
Some of Russia's largest mills are installed at this factory, but the customer has constantly faced issues with their motors. For over two years, our specialists together with WEG have been elaborating an equipment replacement project including the required technical improvements, defended it and won the bidding procedure in 2019. 7.5 MW and 9 MW motors are now being installed, commissioned, and started up.
Phosphorite Plant in Kingisepp
A 6.2 MW motor was put into operation in the project of Air Blower Capacity Increase at the Sulfuric Acid Production in 2020.
