FAQs
For 690 V, 50 Hz operation, install with a Y connection as specified, using the IMB5/IM3001 mounting arrangement and D-End top terminal box. Ensure ambient temperature does not exceed 40 C and altitude remains within 1000 m. With 315 kW output and a 4-pole configuration, verify mechanical alignment and suitable VFD compatibility to achieve smooth soft-start and reliable acceleration.
IE5 efficiency translates directly into reduced energy consumption during continuous operation. At full load the motor delivers about 97.1% efficiency, with 96.9% at 75% load and 96.1% at 50% load, meaning meaningful savings across typical duty cycles in pumps, fans, and compressors. Over asset life, these gains lower energy bills and improve sustainability metrics without sacrificing performance.
Yes. The motor features Exeb explosion protection suitable for IIC gas groups and carries an IP55 enclosure, offering dust and moisture resistance in harsh areas. These protections ensure safer operation in chemical plants, oil and gas facilities, and other demanding process environments while maintaining high reliability and uptime.
Follow standard bearing and alignment checks aligned with IMB5/IM3001 mounting requirements. Schedule regular inspection of the 6319/C3 bearing set and shaft alignment, monitor insulation resistance, and verify cooling provisions for continuous duty. Use ABB-approved drive systems for torque control and routine VFD parameter optimization to preserve IE5 performance over time.
Industry-fit applications include heavy process automation in chemical, oil & gas, mining, power, and pulp and paper sectors. The 315 kW, 690 V SynRM with Exeb protection and IP55 is ideal for environments requiring high efficiency, robust enclosure, and reliability under challenging conditions, such as pumps, fans, compressors, and conveying systems in hazardous zones.
