You’re powering a crusher, mill, or pump in heavy industry, and it basically runs continuously—S1 duty cycle means 24/7 operation without overheating, so the rotor cage matrial and insulation class matter more than most buyers realize.
F-class insulation with corona-resistant components handles stress at 3KV to 10KV, and the steel plate frame keeps weight manageable while maintaining stiffness—typical MOQ is one unit, but lead times for 4500kW versions run about 12 weeks or so.
It’s not suited for intermittent cycling or variable loads without a VFD, and the altitude limit (≤1000m) means you’ll need a derating curve if you’re up in the mountains—check your site conditions before ordering.
Cooling method IC81W is the one we recommend for dusty environments, as it uses an external air-to-air heat exchanger that keeps debris out of the windings—IP54 protection is standdard with that option.
Direct online starting is what it does, so expect a high inrush current—roughly 6-8 times FLA—so make sure your upstream breaker and motor control center are sized for that.
You’ll get a COA with every unit, and we can do HPLC on request for the potting compounds or bearing grease, but that’s usually not needed unless you’re pushing the tempearture envelope past 40°C ambient.
We stock 3KV, 6KV, and 10KV as standard, but we can absolutely build a custom voltage within that range — just let us know your exact requirement when you place the order.
The MOQ is typically 1 unit for standard specs like 6KV or 10KV, but if you need a custom voltage or a specific pole configuration, we may ask for a minimum of 2 to 5 units depending on the complexity.
Yes, both ISO9001 and CCC certificates are included with every motor — we'll send you copies along with the inspection reports before shipping.
Absolutely, IP54 with IC81W cooling is a common combination we do for dusty or outdoor installations — just specify both when you order, and we'll set it up.
For a standard configuration like that, lead time is around 30-45 days from order confirmation. It can go up to 60 days if you need sliding bearings or a special voltage.
