Description
About the 1PH8286-1AF40-2BU2
About the 1PH8286-1AF40-2BU2
The Siemens 1PH8286-1AF40-2BU2 is a SIMOTICS M-1PH8 compact asynchronous motor rated 382 kW and 2432 Nm at 1500 r/min, extending to 500 kW at 2000 r/min in the field-weakening range. Built to IP23 with open-circuit ventilation, it has a 280 mm shaft height, carries a Pt1000 temperature sensor with no encoder, and weighs 1400 kg.
Selection Notes
The IP23 open-circuit ventilation on the 1PH8286-1AF40-2BU2 gives it a higher continuous rating in the 280 mm frame than a forced-ventilation IP55 winding, delivering 382 kW and 730 A at 1500 r/min, rising to 500 kW once the field-weakening range is reached on a 480 V supply. Its 20-minute thermal time constant is shorter than an IP55 sibling's, so it needs a cleaner cooling air path and leaves less margin against sustained overload. Pick the IP55 forced-ventilation version instead when the installation is dusty or exposed to washdown.
