We’re talking about a constant-speed three-phase motor here, the LR model, built for general industiral use with direct online starting and a closed-type casing that keeps debris out. Most buyers go with teh 380V option, but you’ve got 220V, 440V, or 690V to pick form depending on your setup—and it handles both 50Hz and 60Hz frequencies without a fuss.
It’s got a copper core winding and high-hardness shaft, which basically means it’ll take a beating and keep running in wet or dusty environments since the protection grade is IP68 (fully submersible, not just splash-proof). Efficieny runs between 77.3% and 82.5% depending on model, so it’s not the energy saver but better than some older designs for continuous duty.
The insulation is Class F, so you can push it pretty hard thermally without it giving up early. One thing we’ve noticed with these is the shaft hardness holds up better than cheaper motors when you’re coupling to pumps or conveyors that have a bit of vibration—it doesn’t wear the bearing seat as fast.
You’ll need to check lead time on the 690V version since we usually stock the 380V and 440V, but the 690V is typically made to order in about 20 days or so. Each unit ships with a COA and the ISO9001 and CCC certs are on file—we don’t include them in the box unless you ask.
Also, this is a 4-pole motor, so it runs at roughly 1500 RPM on 50Hz and 1800 RPM on 60Hz—good for fans, compressors, and general machinery. Just don’t use it for variable speed drives without a proper inverter-rated motor; direct-on-line starting is what it’s built for.
We typically set MOQ at 50 units for standard models, but we can negotiate lower quantities for first-time buyers or sample orders. Just reach out and we'll see what works.
Lead time is usually 15 to 20 working days after order confirmation and deposit. For larger batches or custom specs, it might stretch to 25 days, but we'll keep you posted.
Absolutely, we include ISO9001 and CCC certificates with every order. Just let us know if you need any other compliance documents for your region.
The shaft diameter is 28mm with a tolerance of h6 for standard models. If you need a different size for your coupling, we can adjust during production.
Each motor is individually wrapped in waterproof plastic, then packed in reinforced plywood crates with foam cushioning. We also add rust-proofing agents for sea freight.
