A new assembly line for its low voltage (LV) premium efficiency WEG IE3 electric motors is yet another advance by Zest WEG in sustainability and local economic impact.
Zest WEG CEO Eduardo Werninghaus says the addition of the new facility is an important contribution to local manufacturing capacity in South Africa. It improves flexibility in the company’s electric motor supply chain, and ensures prompt delivery times for customers. The line produces WEG W22 IE3 LV motors in various sizes, offering high reliability in all applications.

“As a Level 1 B-BBEE company, our commitment to transformation includes continuous promotion of local manufacture,” says Eduardo. “Our focus on premium efficiency IE3 motors is also significant as it helps drive energy efficiency – a key sustainability goal for mines and other industries.”
The assembly line required considerable investment in equipment including jib cranes for easier materials handling, an air reticulation system to feed compressed air to the pneumatic tools on the line as well as to the spray booth and packaging equipment, enhancing the efficiency of the production processes and a state-of-the-art test panel.
Futureproofing
As with any world class manufacturing and assembly operation, record-keeping is an important cornerstone. The panel is therefore synchronised with the advanced WEG manufacturing facilities in Brazil, for complete and accurate record tracking and evaluation. Each motor undergoes routine testing which includes winding resistance tests, accessories tests, insulation resistance tests and no-load tests.
“Further ensuring operational efficiency, the line was capacitated with state-of-the-art equipment including a heating and greasing facility as well as rotor assembly C-hooks,” says Sindi Mbhalati, Operations Executive at Zest WEG. “In addition and, most importantly, the assembly line has been engineered to allow multiple shifts to be worked should it become necessary to increase capacity and output. This type of futureproofing to accommodate market demands is in line with Zest WEG’s commitment to its customers.”
Rigorous training
She highlights that Zest WEG’s quality control personnel are rigorously trained to assess motors during the build process as well as final quality inspection and testing. All aspects are aligned with WEG quality procedures, ensuring world class standards are maintained across all operating parameters.
