FAQs
The unit uses a cast-iron frame size 315 with IMB3/IM1001 mounting. Install on a solid base, connect to a 690 V, 50 Hz three-phase supply using a Y configuration, and ensure proper alignment with the driven equipment. Verify IP55 enclosure integrity and secure the terminator box at the D-End top. Follow impedance and torque requirements outlined by the IMB3 mounting guidelines to minimize vibration and maximize bearing life.
IE5 efficiency indicates near-maximum efficiency for asynchronous drive operation, reducing energy losses during full-load and partial-load conditions. For continuous-duty applications, this translates to lower electricity consumption, improved power factor, and reduced cooling requirements, thereby lowering total cost of ownership over the motor’s lifetime.
Yes. The 3GHL312812-AUC is designed for hazardous areas with Exeb protection, suitable for IIC gas groups. It carries IP55 enclosure protection, protecting internal components from dust and moisture ingress, and supports safe operation in classified zones when installed per local standards and appropriate electrical installation practices.
Best for heavy-duty, continuous-duty scenarios such as grinding, conveying, pumping, and chemical processing where reliable torque and efficiency matter. The motor’s 315 frame, IP55 enclosure, and Exeb protection make it ideal for harsh environments, while its 4-pole design offers robust starting torque and smooth speed regulation with modern VFDs.
Expect extended service intervals due to robust cast-iron construction, IMB3/IM1001 mounting, and reliable bearing configurations (6319/C3 and 6316/C3VL0241). Coupled with IE5 efficiency, the rotor design reduces energy losses and cooling demands, delivering a favorable return on investment through energy savings, uptime improvements, and lower maintenance costs in hazardous-area operations.
