HIGHER EFFICIENCY MOTORS (HEM)
Super premium Efficiency (IE4) motors IE4 MOTOR The higher price of the IE4 motors is due to : 1. the use of high-quality materials and optimization of assembly and design of these motors to achieve higher efficiencies upto 97% . 2. Large-diameter copper wires and more quantity of aluminum are used in rotors of these motors to reduce the resistance losses. 3. An optimized cooling fan is also used to reduce the winding losses. 4. use of advanced technologies like diecast copper rotors enables achieving higher efficiencies in the same frame size. The use of the high-quality, expensive materials increases the overall cost of this type of motors. adoption of energy efficient technologies to reduce their energy consumption and carbon emission. 5. Stator and Rotor I2R losses: Stator and Rotor I²R losses appear when heat is generated by resistance from current flowing in the stator windings, rotor conductor bars. These are major losses, typically account for 55% to 60% of tota
