Perfect for the production of energy at variable speed (from wind, from “screw” turbines, etc…), they have the following main characteristics:
– permanent magnet rotor in “rare earth” Nd-Fe-B;
– no excitation winding, no carbon brush, no sliding ring;
– simple, reliable, durable and maintenance-free structure;
– multipolar design, for better frequency efficiency of rectifiers and inverters;
– can replace asynchronous motors;
– insulation class H, vacuum impregnation;
– with SKF bearings;
– power factor close to 1, no need for power factor compensation;
– low heat production, additional fan or water cooling in larger units;
– lifespan > 20 years, continuous operation;
– high efficiency, energy saving.
– patented “Precise Coil” technology: thanks to this recent technology, hysteresis is avoided by obtaining a very low starting torque (<1nm);
– original structure: very compact design;
– perfect for low-speed applications, no gearbox needed, direct transmission;
– high quality components for use in extreme environments;
– low energy loss, low mechanical strength, high efficiency;
– high heat dissipation due to aluminum alloy exterior case and special internal structure.
