We’re looking at the YSF series for your driving equipment, and the cast iron frame gives it good heat dissipation and mechancial strength—basically, it’s built for constant-speed, three-phase industrial work in the 1.5 to 22 kW range.
Effiency varies a bit, from 69% to 91% depending on the pole count you need, and the power factor runs between 0.72 and 0.90; most buyers go with the 4-pole option for balanced performence, but we’ve seen 2-pole for higher speeds in some cases.
IP55 protection means it handles dust and water jets fine, though it’s not suited for submersion—so check your environment if there’s standing water. Noise level is roughly 57 to 92 dB, and the 50Hz frequency is standard for most industrial setups.
One thing you might not think to ask: the insulation class is 155(F) at rated load, but it actually operates at 130(B) class under direct online starting, so it runs cooler than the spec suggests. Also, maximum altitude is 1000m above sea level, so if you’re higher than that, we usually have stock but confirm lead time.
For ordering, the gentian blue RAL 5010 finish is standard, and our company offer both cast iron and aluminum housing options—cast iron is heavier but more durable, alumnum is lighter for some applications. MOQ is usually 10 units or so, but our company can do smaller batches if you’re testing.
We can do sample orders of 1-2 units for testing, but standard MOQ starts at 10 pieces per model. Just let us know which pole and power specs you need, and we'll work out the details.
For standard models like that, lead time is usually 15-20 working days after order confirmation and payment. Custom specs might add a few days, but we'll confirm when you place the order.
Yes, we include both ISO9001 and CCC certificates with every shipment, and we can send you digital copies upfront for your review or compliance paperwork.
It depends on both. Higher power ratings and lower pole counts (like 2-pole) tend to hit the 91% end, while smaller motors or 10-pole versions run closer to 69%. We can give you the exact efficiency for your specific model choice.
Store it in a dry, covered area with the shaft coated in anti-rust oil. Since it's IP55, it's dust-tight and splash-proof, but for long-term storage, keep the ambient temperature between -15°C and 40°C and avoid direct rain.
