Dyneo Solutions Pure efficiency ® Dyneo® solutions combine permanent magnet motor technologies with variable speed technologies. Benefiting from more than 15 years' experience, these solutions offer not only tried-and-tested technology, a rapid return on investment, but also one of the most favorable overall costs of ownership on the market. Tests conducted by the Swedish Energy Agency ranked Dyneo® motor and drive assemblies best in the high efficiency category. The latest developments now offer users simplicity of installation equivalent to that of an asynchronous motor, mainly thanks to...

Energy savings The use of variable speed, and the optimization of mechanical systems, are the main means of achieving maximum savings. The adoption of Dyneo® motor-drive unit solutions optimizes energy consumption savings. • Energy savings, reduction in costs of use and installation 50 kWh Variable speed & IE2 motors 65 kWh IE3 motors 80 kWh Mechanical optim isation 85 kWh Original solu tion 100 kWh Exceptional efficiency levels over the whole operating speed range, especially at speeds below the synchronous speed where efficiency is much higher than with asynchronous motors Energy savings...

Dyneo® Solutions The flexibility and simplicity of a tried-and-tested technology Sensorless control The product of long experience in variable speed control and permanent magnet motors, Dyneo® solutions provide total sensorless control of the majority of process applications (pumps, compressors, fans, pressure boosters, centrifuges, separators). The aim is to offer the user the benefit of the excellent performance of permanent magnet motors with a simplicity of mounting and installation equivalent to asynchronous motors. Advantages of sensorless mode Less wiring saves time • No...

LSRPM/PLSRPM permanent magnet motors are built using the same mechanical components as asynchronous motors, and offer reliability, a wealth of options, flexible adaptation and short delivery. The range is available in two variants in order to meet the needs of customers, whether users or manufacturers: Interchangeable range The 1500 range is available with an standard IEC dimensions identical to asynchronous motors with the same power rating: • Immediate interchangeability thanks to standard dimensions in terms of frame size, flange and shaft extension Immediate benefit of a premium...
