You're likely sourcing for a production line running pumps or machine tools where downtime isn't an option, and the standard cast-iron frames just add unnecessary weight to the assembly. We've seen buyers switch form older Y2 models to these Y3 aluminum bodies specifically for the weight reduction—roughly 30% lighter than steel equivalents—which simplifies mounting and reduces structrual load on the frame.
F class insulation handles a 155°C hot spot, which gives you a 25°C safety margin over typical B class at full load, and that's worth having when ambient temps in a pump house hit 40°C or so. The TEFC enclosure with IP54 or IP55 protection means it's sealed against dust and hose-directed water, so you're not worrying about coolant splash on a lathe or washdown cycles.
Power range covers 0.12kW up to 315kW, with 2, 4, 6, 8, 10, or 12 pole configurations depending on your torque-speed curve—most buyers go with teh 4-pole for general pump duty, actually. Voltage is 220V/380V as standard, but our company can adjust that to your local distribution, and frequency is either 50Hz or 60Hz without derating the alumnum housing.
What you get when ordering is a motor with direct-on-line starting capability, IC411 cooling (that's the shaft-mounted fan), and mounting options B3, B5, or B35—pick the flange or foot configuration that matches your existing baseplate. CE and ISO9001 certs are included with every unit, and we usually have stock for the popular 5.5kW to 30kW range, but confirm lead time on the 315kW if you need it quickly.
Noise levels are low—typically under 70 dBA for the smaller frames—and vibration stays within grade N limits, so you're not introducing harmonics into a precision tooling setup. It's not suited for explosive atmospheres without an ATEX enclosure though, so check your zone classification if that's your use case.
Packging is standard export-grade plywood crates for anything above 15kW, smaller units go in corrugated boxes with foam inserts, and we include a paper COA with the HPLC purity data for the insulation material (yes, we track that on the varnish). The 0.37kW model is a common pick for conveyor belts in food processing, and that one ships in a box you can carry with one hand.
Typically 25 to 35 working days for that power range and efficiency class, depending on current production load. We can give you a tighter estimate once you confirm the exact specs.
Yes, we include a CE declaration and a routine test report for every motor. If you need additional documents like a material certificate or a detailed test protocol, just let us know in your order notes.
Absolutely, we can wind the motor for 400V 50Hz or 460V 60Hz on any Y3 frame size. Just specify the voltage and frequency when you place the order.
They come packed on plywood pallets with a shrink wrap and a protective carton. For outdoor storage, keep them under a roof or tarp — the IP54/IP55 rating handles rain, but prolonged sun and moisture will degrade the packaging.
F class insulation works fine for VFD-fed motors if you keep the temperature rise within its limit, but for heavy inverter duty we usually recommend H class to give more thermal headroom. If you go with F class, a shaft grounding ring is a good idea to prevent bearing currents.
