WONDER SWE Series three phase asynchronous induction cast iron motors with IE3 efficiency. New design for IE3 and IE2 motors instead of modifying the standard motors by enlarging the frame size or lengthening the lamination. Thus, our efforts result in good interchangeability among IE4, IE3, IE2 and IE1 versions. All the lines designed and produced by Wonder are equipped with perfect insulation system. Stators are well insulated with highest standard winding and insulation materials., such as slot liners, slot separators, phase separators, wedges, banding tapes, impregnating media, tapes and sleeving, etc. In addition to aging test, other test such as melting temperature, tensile strength, resistance to heat shock, cut through resistance etc. are also performed to ensure that the insulation system can withstand known operating conditions. The use of VFD and switching frequency are major driving forces to save energy. For VFD application, Wonder motors are fitted with class H copper wire, enhanced insulation materials, and insulated bearings or insulated end shield, which provides a good solution for new tech applications in all industry. For frequency between 25-50Hz, there is no need to install forced ventilator for Wonder motors. Main Tech Specifications: Frame Size: 80-355mm Output Power: 0.37-315kW Speed: 3000, 1500, 1000, 750r/m Poles: 2, 4, 6, 8 Protection Class: IP55 or above Insulation Class: F or above Cooling Method: IC411/IC416 Applications: Pump Motors Compressor Motors Ventilation Fan Motor Motors With Gearbox Wind Turbine Generator Motor Grain Mill Motor Centrifugal Motor Elevators Motors Packaging Equipment Motors Grinders Motors Conveyor Belt Motors
