CPQD to support WEG on tests evaluation for private 5G networks use in Industry 4.0
[ad_1]
Analyze, from a technical and economical point of view, the use of private 5G networks technology in the Industry 4.0. This is the purpose of the agreement recently signed between CPQD (Research and Development Center) and the partners who have been conducting the Open Lab 5G project: Brazilian Agency for Industrial Development (ABDI), Anatel and WEG / V2COM Group.
The starting point for this project was a technical cooperation agreement, signed in November, between Anatel and ABDI, with a focus on conducting tests of private 5G networks in industrial production areas. The first trial test is taking place in one of WEG’s factories, located in Jaraguá do Sul, state of Santa Catarina, where CPQD will be providing consulting services and technical analysis (performance) and economic viability of this application.
“The objective is to evaluate different connectivity solutions to be used in Industry 4.0”, says Gustavo Correa Lima, leader of the Wireless Communications Platform at CPQD. “This includes benchmarking between public and private 5G networks and comparing these solutions with other connectivity technologies, both wired and wireless, such as Wi-Fi and fiber optics,” he explains.
The place where the tests will be carried out is one of the most robotized factories with the highest level of automation and monitoring of WEG’s shop floor. As stated by Guilherme Spina, director of V2COM, a WEG Group company, this real operating factory will allow to test more than one 5G network. “We will have different network architecture implementations, one conventional and one virtualized, and we will also test antennas and 5G devices using millimeter waves, as well as sub 6 GHz. These tests will provide data and information to Anatel to support the process of defining requirements and conditions for the use of frequency bands for the regulation and authorization of private networks for industrial use”, says Guilherme.
Expected to be concluded within seven months, the project to be carried out in partnership with CPQD should also generate data for new types of business, considering different environments, which may help companies in other economic segments.

WEG Branch in Russia steps towards Mining Industry with reliable solutions
[ad_1]
This is another important supply made by the WEG´s Russian Commercial Operation (WRU) for the customer PJSC Polyus Gold, in the Magadan Region, the largest gold producer in Russia.
The scope of supply included a pair of Slip Ring Motors of 9000 KW at 1000rpm, and another two motors of 7500 KW also at 1000rpm and fully designed to be interchangeable with the old existing motors providing a smooth drop-in replacement.
The motors will be applied, in pairs, at huge SAG and Ball mills that operate through dual pinion drive summing their power to each mill.
Historically, the customer was facing a troublesome operation due to a number of different reasons such as mechanical fits, overheating of antifriction bearings and electrical overload events.
With prompt attention to the customer, the WEG team evaluated different options in order to offer the most reliable product. A robust design of slip ring rotor motors was recommended including reliable features such as fixed or liftable brushes, internal or external slip ring chamber and different series of sleeve bearings or antifriction bearing in oil bath.
The final design was approved after customer inspection at WEG headquarters facilities in Brazil and a technical visit to a cooper mine in Chile where similar WEG motors are successfully operating.
A key factor for this project was the local WEG specialists in the market providing fast response to the customer and listening carefully to the customer needs.
The WEG Slip Ring Mining motors were designed in such a way to allow another technical key factor for this project where they can operate both as a slip ring motor or as an induction motor fed by inverter when the temperature is very cold (-50°C) and the ore inside the mills gets frozen and then the mills speed can be automatically controlled.
The electric motors were delivered in July 2020. Due to sanitary restrictions, the commissioning was postponed to December and work was carried out from November 15 to December 23, 2020.
