Reluctance brushless DC Compressor
The reluctance brushless DC motor provides significant increases in efficiency compared to conventional AC inverter motors, simultaneously using
2 different forms of torque (normal and reluctance torque) to produce extra power from small electric currents.
The motor comprises powerful neodymium magnets, that create the reluctance torque. These magnets ar approximately 12 times stronger than ferrite
magnets and make a major contribution to its energy saving characteristics.
