FAQs
This motor is designed for hazardous-area operation in chemical processing, refining, and mining. It features Exdb flameproof protection, IP55 ingress protection, and Gas Group IIB protection, enabling safe and compliant performance in explosive atmospheres. It supports ambient conditions up to 50 °C and altitudes up to 1000 m, with robust mechanicals for long service life.
Yes. The unit is rated for continuous S1 duty and employs an 8-pole design, delivering stable torque and reliable speed under steady-state operation. This combination is well-suited for pumps, fans, and conveyors in hazardous environments where uptime and torque consistency matter.
The motor uses a 280 frame with cast-iron construction and a D-End top termination box location, facilitating straightforward wiring and retrofits. With its IMB3 IM1001 class construction, it integrates smoothly with common industrial bases and mounting schemes used in hazardous-area facilities.
Installers should follow ATEX/IECEx guidelines, maintain IP55 sealing, ensure proper cooling, and provide accessible termination points at the D-End top. Verify correct alignment with existing drive trains, and plan for crane/handling requirements due to the motor’s weight (net ~645 kg). Regular inspections of flameproof enclosures are advised to sustain compliance.
IE2 efficiency for this motor is around 90.7% at full load, 90.3% at 75% load, and 89.1% at 50% load. In continuous operations, this translates to meaningful energy savings and reduced operating costs, improving return on investment when measured against less efficient replacements, especially in high-hour applications such as pumps and fans in hazardous facilities.
