ABB launches IE6 motor for hazardous-area oil and gas applications
What happened
ABB introduced what it calls the world’s first IE6 hyper‑efficiency synchronous reluctance motor certified for hazardous‑area (ATEX/IECEx) use. The product targets compressors, pumps and fans and is designed to work with variable speed drives, with initial ratings beginning at 110 kW and claims of substantially lower losses versus IE3 units. Watch whether OEMs and service providers update retrofit scopes, warranty language and VSD compatibility checks before buyers issue upgrade RFQs
Buyer takeaway
Treat this release as an operationally real retrofit option that will require explicit contract language for drive compatibility, certification transfer and warranty scope
Cost / money
Directional reduction in operating electricity and lifecycle cost is plausible given continuous duty use; buyers must weigh retrofit CAPEX against OPEX reductions and spare‑parts shifts
Supplier / commercial
OEMs and service contractors may add integration and certification fees to retrofit quotes or limit warranty coverage unless scope is tightly defined
Safety / operations
The ATEX/IECEx certification plus lower running temperatures can permit Increased Safety designs in some Zone 1 cases, changing onsite maintenance procedures and permitting needs
What to watch
Verify physical and VSD compatibility at candidate sites and insist on factory acceptance tests for hazardous‑area installations before large rollouts
Key facts
- Certified for ATEX/IECEx Zones 1 and 2
- Initial line starts at 110 kW and supports VSD operation
- Manufacturer claims significantly lower energy losses versus IE3 designs
Source excerpts
The company said the motor is designed as a high-efficiency replacement for conventional IE3 induction motors used in pumps, compressors and fans. ABB said the magnet- and rare earth-free motor can reduce energy losses by as much as 60% compared with standard IE3 motors, potentially offering significant operating cost savings for facilities that run continuously
In some Zone 1 applications, the cooler operating temperatures of the motor could allow operators to use an Increased Safety motor instead of more complex flameproof motor designs. ABB also said the technology’s higher loadability in Zone 2 environments may allow smaller motors to perform the same duty as larger induction motors
The IE6 SynRM Increased Safety motor is certified for use with variable speed drives, allowing operators to optimize efficiency across varying load conditions
