You’ve got a few options here across efficiency classes IE1 through IE4, basically covering the full ladder from basic to premium. The power range covers 0.37kW to 400kW, so 1HP up to about 460HP — depends on your driver setup obviously. That copper winding is the main reason these hold up under continuous load, especially at S1 duty cycle where you’re running them for hours. Most buyers I work with go for the IE3 tier straight off, mainly because utilities rebates are better and payback hits within a year or so.
Mounting types are B3, B5, B14, B34, B35, and C Face — which sounds like a lot, but we usually only keep stock on B3 and B5 for the common frame sizes. If you need a C Face for a gearbox adapter or something non-standard, that’s where their OEM flexibility comes in. The voltage range is 220V to 660V, three-phase, 50Hz or 60Hz — and they can tweak the wiring for your local grid if you ask. Speed runs 740 to 2800 RPM depending on pole count (2,4,6,8,10), so you’ll get roughly 300-400 RPM variance per pole step down form 1500 RPM base rating anyway. DOL starting is the standard here, but they won’t push soft start or variable frequency drive configurations out of the box — that’s on your end to add.
Protection class runs from IP22 on basic open-drip models up to IP66 for fully sealed washdown environments, but don’t expect IP66 on anything above 200kW without checking the housing material first. You'll get cast iron on most heavy-duty frames, aluminum for lighter builds, steel for weldments, and stainles steel where corrosion eats shafts regularly. Insulation classes E, B, F, and H — an H-class motor with a service factor 1.15 will handle higher ambient temps better, but the F-class is usually spec’d for standard factory floor installs. One thing that surprised me is how well the YS and MS series handle voltage fluctuation — they stay within tolerance better than the basic Y2 frames when line power drops.
Also don’t order the YVP variant if your only need is constant speed — it’s designed specifically for variable torque loads and adds complexity you don’t want. Certification-wise, you’ll find ISO9001 as a given, plus CCC if you’re shipping into China, UL for North America, GOST for Russia — although the GOST cert usually adds 4-6 weeks to lead time. The standard models Y, Y2, YS, MS, YB2, YB3, YEJ, YVP cover explosion-proof, brake motor, and inverter-duty types too, but the explosion-proof YB series has a painted socket lock that’s a real pain to remove if you ever need to swap leads. Anyway, the packaging details are in the quote — their pallet crating is better than most, just make sure you request individual motor pull straps if going into tight vault enclosures.
0.37kW at 740 RPM is basically a torque motor for indexing or light conveyor work, not for high-inertia starts — you’ll stall it if you try that. We had to order the aluminum housing version for a clean room appliction and it passed fugitive emission testing on the third attempt when the IP rating was downgraded to IP55 for heat dissipation. This really isn’t a product for consumer-grade anything — it’s all industrial IEC flange and foot mount standard with DIN and BSI stamping, so don’t try running it off single-phase without a phase converter because that will cook the winding insulation in maybe 20 minutes. The duty cycle S1 is continuous, S2 is short-term, S3 is intermittent periodic — and most customers we see end up over-specifying S1 when S2 saves both weight and cost for cycling apps. In most cases, lead time is 45 days for a custom frame, but we usually have stock for standard ready-mount units within 5 business days — just confirm with your rep before committing ship dates.
MOQ depends on the model and specs, but for standard configurations like Y2 or MS series in cast iron, we usually start at 50 units. For aluminum housing or stainless steel, it can be higher, so just share your volume and we'll confirm.
For IE4 motors up to 200kW with B5 mount, lead time is around 30-45 days after order confirmation. If you need a rush, we can sometimes cut it to 25 days for smaller quantities.
Yes, we can supply UL-certified motors across the full voltage range, but it's only available for certain model series like Y and Y2. Just specify UL requirement in your order, and we'll handle the documentation.
Our standard winding material is copper for all motors, and we don't offer aluminum windings. If you need a different conductor, let us know the specifics, and we can check feasibility for large orders.
We can pack them in sealed plywood cases with moisture-proof lining and desiccants. For IP66-rated motors, that's usually enough for up to 12 months in storage. Just mention the storage conditions when you place the order.
