Power demanding speed-controlled equipment with a low-voltage, high-power VFD asynchronous motor series sized for serious industrial duty. The YPT (355–710) family — as described in Chinese manufacturer catalogs and on our HKTDC listing — is developed for steel-industry and similar drives that need variable frequency control: rolling mills, coilers, levelers, shears, fans, and pumps. Motors in this series are designed to be powered by a variable frequency drive (VFD), supporting flexible rated-speed selection rather than a single fixed line frequency.

Public series literature commonly references center heights in the 355–710 mm class, low-voltage supplies (examples in catalogs include 380 V / 660 V / 690 V class — please confirm your order voltage), insulation grade F or H, and forced-cooling arrangements such as IC06 / IC416 / air-to-air cooler options depending on frame and maker. Mounting is commonly IM1001; thermal protection options such as PT100/PTC appear in selection guides. Performance and outline dimensions in mainland catalogs are positioned to support localization / replacement of imported equivalents — always verify the outline drawing against your foundation.

PYTHAGORAS HK TRADE LIMITED (Hong Kong) trades this series under the Pythagoras brand on HKTDC, with customization available for project matches. Send us power (kW), rated speed/frequency, voltage, cooling preference, and duty — we will return clarifying questions and a quotation path quickly.

These points synthesize public YPT catalog ranges plus the existing HKTDC listing. They are orientation ranges, not a Pythagoras factory nameplate. Manufacturing partners can provide applicable certificates for the supplied lot — available on request.
