ABB Group offers comprehensive drive solutions clearly categorized into low-voltage and medium-voltage motor groups. These motor lines cater to a wide range of applications, spanning from residential and light industrial use to heavy-duty industrial sectors.
1. ABB Low Voltage Motors
ABB low-voltage motors operate at standard voltage levels (below 1000V; commonly 220V, 380V, 410V, and 690V in Vietnam). This is the most widely used product group, serving applications ranging from manufacturing plants to building pump and fan systems.
• General Performance Motors:
- M2BAX (Cast iron frame): The "market-standard" product line holding the largest market share in Vietnam. Optimized for basic applications such as pumps, fans, and conveyors. Available in IE2 and IE3 efficiency classes.
- M3AA (Aluminum frame): Lightweight with excellent heat dissipation. Ideal for installations requiring reduced structural load or for integration into OEM machinery.
• Process Performance Motors:
- M3BP (Cast iron frame): The premium low-voltage motor line, featuring a highly durable design for harsh heavy-industrial environments (chemicals, mining, steel). Offers ultra-high efficiency (IE3, IE4) and extended bearing service life.
• Synchronous Reluctance Motors (SynRM):
- SynRM Motors (IE5, IE6): Advanced technology utilizing neither permanent magnets nor carbon brushes. These ultra-energy-efficient motors are typically paired with ABB variable speed drives (VSDs) to optimize operating costs for factories aiming for Net Zero emissions. • Specialized Motor Series:
o Explosion-proof motors (M2JA, M3GP, M3KP): Meet strict ATEX explosion-proof standards for the oil & gas and mining industries.

2. ABB Medium Voltage Motors
ABB medium voltage motors operate at high voltage levels (typically ranging from 3.3 kV and 6.6 kV to 11 kV in Vietnam) with massive power outputs ranging from several hundred kW to tens of MW. They are imported directly for major projects such as cement plants, thermal power plants, and oil refineries (e.g., Dung Quat, Nui Phao, Tan Thang).
• Standard Squirrel-Cage Motor Series (High Voltage Rib-Cooled Motors):
- NXR Series: ABB’s new-generation medium voltage motor series featuring rib-cooled technology. The NXR series offers optimized dimensions, quiet operation, easy maintenance, and very high power density.
- AXR Series: Similar to the NXR but typically subject to deeper customization based on the specific mechanical structure of each plant.
• Large-Capacity Modular Motor Series (Modular Induction Motors):
- AMI / AMD / M3BM Series: Modular motor series (featuring a square steel housing). This design allows ABB to integrate various cooling systems (such as water cooling IC81W or recirculating air cooling IC611) depending on the available space in the machinery room. Power output can reach tens of MW.
• Wound-Rotor Motor Series (Slip Ring Motors):
o BMD Series: Medium voltage wound-rotor motors, specialized for applications requiring extremely high starting torque, such as stone crushers, cement clinker mills, or mineral conveyors spanning several kilometers. ________________________________________
