Description
Available is one large Siemens 1RA5 319-4ZZ99Z three-phase motor, made in Germany. The supplied nameplates identify motor number 473894/1988, mounting designation IM V1, insulation class F, IP23, separately cooled operation, and multi-frequency electrical ratings.
The principal readable nameplate point is 246 kW (330 HP), 570 V delta, 45 Hz, 300 A, 1,318 RPM, and 0.89 power factor. A second clearly readable point is 165 kW (220 HP), 380 V delta, 30 Hz, 310 A, 866 RPM, and 0.89 power factor. The plate also contains additional 68 Hz / 1,990 RPM and 45 Hz / 1,278 RPM entries. Buyer must verify the complete voltage, frequency, current, power, speed, control, and cooling requirements directly from the physical plates and applicable manufacturer documentation before installation.
The physical motor includes a large top-mounted cooling-air duct/inlet and the nameplate states separately cooled / forced cooling: 0.9 m³/s. The external cooling supply, fan, ductwork, and controls required for operation are not represented as included unless physically present and confirmed at inspection.
Condition disclosure: A physical status tag identifies this motor as failed. No failure mode, electrical test result, mechanical inspection result, repair history, or repair scope has been supplied. The terminal connection hardware is exposed in the photographs, and no terminal-box cover is represented as included. This motor is offered strictly as-is for evaluation, repair, rebuild, or component recovery and is not represented as ready for installation or service.
