Low voltage (LV) flameproof motors are now available in smaller frame sizes, offering the safety, reliability and efficiency of larger motors.
The motors are particularly useful in hazardous and explosive environments, as found in the oil and gas, chemical and mining industries.
The smaller motors still offer customers the flexibility to add features like bearing vibration and temperature monitors, which can alert operators to performance errors and potentially reduce unexpected downtime. The motors are coated in a surface treatment aimed to withstand harsh environmental conditions, such as those experienced on an offshore oilrig.
ABB’s new low voltage IEC LV flameproof motors are available in frame sizes 80 – 132 and offer the same safety and efficiency features usually found in ABB’s larger products.
The company also offers an IE3 low voltage flameproof range that covers frame sizes 80 to 450.
The motors have multiple lifting lugs to make them easier to handle. The option to fit an auxiliary terminal box aims to enhance safety in applications where sensors or anti-condensation heaters are needed, as it keeps the auxiliary connections separate from the motor supply terminal box.
The units are available in IE2 and IE3 efficiency classes. They are supplied with ATEX and global IECEx certification, and are certified for use with variable speed drives. The motors are available in 2-8 pole versions, in all common voltages, for both 50 Hz and 60 Hz.
An IE3 range of standard, flameproof (Ex db and Ex db eb), increased safety (Ex ec) and dust ignition protection (Ex t) motors are on offer, particularly important for customers in countries where these types of motors are covered by Minimum Energy Performance Standard requirements.
