One of the most promising directions of our company's activities is design and production of different types of equipment, based on rare-earth NdFeB magnets, such as engine rotors or generators for various applications in many industries.

Taking into consideration specifics of applications, where rotors are used, and requirements to their operation, Research & Production Company «ERGA» produces rotors, based on high-power permanent magnets and bonded magnets.

Rotors, based on rare-earth permanent magnets or bonded magnets, have a number of advantages over similar products:

• Engines with rotors, based on permanent magnets, provide high starting and rotational moments as well as a high efficiency factor;
• Operation in the harshest conditions: high temperatures, aggressive chemical environments or even vacuum;
• High operation characteristics due to usage of permanent magnets, guaranteeing engine power increase and reducing its wear;
• Simplified engine construction and reduced noise levels;
• Simple construction, reliability and stability of operation;
• Efficient and reliable construction make rotors multi-purpose systems, used in many industries;
• Rotors, based on permanent magnets, ensure low energy consumption.

Research & Production Company «ERGA» has the following designs of new rotors:

• 2-polar rotor, based on SmCo₅ magnets, for cryogenic devices with rotational frequency 110000 rotations/min.;
• 4-polar rotor, based on Sm₂(Co,Fe,CuZz)₁₇ magnets;
• 4-polar rotor, based on NdFeB magnets, for generators w=100 kWatts, rotational frequency - 100000 rotations/min.;
• 24-polar bonded NdFeB magnets for conditioning systems;
• wind motors without the stripping effect, 1 - 5 kWatts;
• multipolar rotors for starter generators, 8 kWatts.

Our company designs and produces standard magnetic rotors, as well as magnetic rotors for individual customers' needs.      

Taking into consideration all requirements and production specifics, our company produces a wide range of rotors with a wide range of characteristics, configurations and sizes.
