The M2JAX high-efficiency explosion-proof motor, developed through ABB's global unified design platform and leading modular design, is a universal low-voltage cast iron high-performance explosion-proof motor for hazardous environments. It has the advantages of ultra-high energy efficiency and extremely high reliability, and can meet the high energy efficiency requirements of the petrochemical industry for motors. Customized solutions can also be provided according to customers' special requirements.

The ABB low-voltage high-performance process motor standard paint system complies with the corrosion category C3M of ISO/EN 12944:2. ISO/EN 12944 divides durability into three ranges: low (L), medium (M), and high (H). Low durability (L) is equivalent to 2-5 years of use, medium durability (M) is equivalent to 5-15 years of use, and high durability (H) is equivalent to more than 15 years of use.

The durability mentioned is not a guaranteed time limit that can be achieved. On the contrary, it is just a technical factor that helps users develop maintenance plans. Due to fading, powdering, contamination, wear, or other reasons, more frequent periodic maintenance is usually required.

The standard corrosion resistant surface treatment level of ABB is C3M (equivalent to moderate corrosion resistance and durability). Other corrosion categories (C4M and C5M) are available as options.

In explosive environments, the combination of frequency converters and motors can provide significant benefits. The advantages include the ability to improve process control by adjusting motor speed, as well as energy saving and thus improving environmental performance.

ABB provides motors suitable for explosive environments, which can be used in conjunction with variable speed drives with the following protection types: explosion-proof, increased safety (as required), spark free, and dust explosion-proof. These motor designs are used in conjunction with frequency converters and have obtained certification. Below are solutions suitable for different protection types and the most common types of frequency converters. For more information, please refer to the installation, operation, maintenance, and safety manual. The explosion-proof, spark free or increased safety Ex ec and dust explosion-proof motors covered in this catalog have been tested in combination with ABB ACS800 and ACS880 frequency converters controlled by DTC, as well as ACS 550 and ACS580 frequency converters controlled by scalar or vector.
