The price and provide of dependable electrical energy has grow to be one of many mining business’s greatest complications, significantly in South Africa. In April this 12 months, the nation’s industrial electrical energy tariff rose above the R1/kWh, taking the price of vitality to exorbitant new ranges. How then do miners compensate for this problem with out ‘breaking the financial institution’?
The incorporation of Zest WEG’s new W22 IE4 motor vary is the right place to begin, electrical motors supervisor FANIE STEYN tells LAURA CORNISH.
The mining business is an vitality intensive person. Even smaller scale operations require large-scale gear to beneficiate ore – all pushed by motors, which collectively account for a good portion of an operation’s whole vitality necessities.
Zest WEG, a specialist motor provider, and likewise an vitality options supplier, has been facilitating price reductions on web site via its vitality environment friendly motor vary, which it first launched to market a few years in the past. “Now we have undergone in depth enhancements on this entrance through the years, shifting from the older IE1 normal effectivity motor to our newly launched IE4 tremendous premium effectivity motor,” Steyn begins. That is a powerful step contemplating the usage of vitality effectivity motors in South Africa (and Africa) just isn’t regulated.

“This step reveals our goal to companion with the business, and the nation, in assuaging their vitality prices. The IE4 motor can add an extra 1 to three% financial savings on vitality consumption over and above these financial savings delivered by the IE3 motor,” Steyn continues. “And importantly, in actually demonstrating our dedication to help the business in its price financial savings, now we have determined to supply our new IE4 motor on the identical worth because the premium effectivity IE3.”
That is important when contemplating the launch of the IE3 motor in 2015 – which Zest WEG provided to market at little or no further price relative to its IE2 motors, with the identical objective in thoughts: Making each clients and the nation extra vitality environment friendly.
Unpacking the IE4 financial savings and advantages
“The effectivity of 96.3% on an IE4-rated 110 kW motor, when in comparison with 94.1% on an IE1-rated motor, can save customers tons of of hundreds of rands in vitality prices over a 10-year interval,” Steyn highlights. “Not solely will these IE4 motors be more economical to run, however they’ve been designed with quite a lot of new options that carry appreciable advantages.”

The WEG IE4 super-premium effectivity motors meet IEC effectivity ranges when operating on 50 to 100% of load. Effectivity is saved fixed, which saves vitality and ensures minimal losses via numerous loading factors. The progressive body design additionally permits most warmth dissipation.
“Motor body design performs an important position in thermal efficiency, as it’s accountable for the outward switch of warmth generated contained in the motor,” says Steyn. “Operating cooler implies that our motors have elevated life spans, permitting Zest WEG to supply a 5 12 months assure on our WEG W22 electrical motor vary.”
The motors’ elevated mechanical rigidity – achieved by integrating the entrance and rear ft sides – affords simpler set up, increased mechanical stiffness and improved distribution of the mechanical thrust imposed by the load.
“As a primary of its sort, our versatile terminal field mounting means lowered stock and faster modification,” he says. “The terminal field might be rotated in 90° increments to facilitate provide cable connection oriented to the entrance, rear, high or both aspect of the motor.”
IE4 offers South Africa the wow issue
South Africa is probably not the quickest in executing or utilizing new or first-world applied sciences however the nation has the higher hand on vitality effectivity via the IE4 motor. “Reinforcing our dedication to at all times provide technological advances which may actually profit our clients, the IE4 motors vary is now being deployed in South Africa as an off-the-shelf merchandise,” Steyn notes.
Accessible within the dimension vary between 37 kW and 355 kW, their utility into the mining sector is wide-ranging.
The IE4 motor can be geared up to learn from Zest WEG’s digitisation technique – with the choice of a motor scan sensor which allows situation monitoring in actual time, and prevents failures by gathering info from the motor which is distributed to the cloud. From there, that knowledge is summarised, tendencies predicted and warnings delivered in an efficient method.
This once more is step one in an even bigger Business 4.0 plan for Zest WEG. “We’re regularly introducing a Motor Scan Resolution in South Africa that takes automation to the following stage. It will entail offering purchasers with entry to an change server which can permit our knowledge to be built-in into our purchasers’ present SCADA programs. Integrating knowledge onto a single platform has grow to be a problem for the business working with so many alternative service suppliers. By way of this resolution, we are going to take away this buyer barrier,” Steyn concludes.
