“…Ferromagnetic material is the main material in the induction motor which is very useful in strengthening the magnetic field of the motor resulting great torque and efficiency in the motor [1]. The performance of these ferromagnetic materials is strongly influenced by the permeability, currents, and the internal and external influences of materials [1,10]. One of the external influences affecting the ferromagnetic materials is the heat that arises in the process of cutting ferromagnetic material either by mechanically or laser, and the effect of welding materials that can decrease the properties of ferromagnetic material [11,12].…”

“…One of the external influences affecting the ferromagnetic materials is the heat that arises in the process of cutting ferromagnetic material either by mechanically or laser, and the effect of welding materials that can decrease the properties of ferromagnetic material [11,12]. In addition, the decrease of the ferromagnetic material properties may also be caused by the influence of heat originating from within the stator core as a result of the magnetization of the stator and from the influence of the surrounding heat as a result of rotor heat induction to the stator [1, 3,10,13]. The heat that occurs in this motor (both from the stator and the rotor) can increase the power loss and decrease the performance and efficiency of the motor [1,2].…”

Induction motors are the most electric motors widely used in the community, both in the industrial and in the household applications. The power and efficiency of the motors are determined by the type of ferromagnetic material used in the core of the motor. If a very good ferromagnetic material with high permeability is applied to the core of the induction motor, then both the energy conversion and the efficiency of the motor will increase. But, if the ferromagnetic material is not good with low permeability is used in the induction motor, of course, the conversion of energy generated by the motor will be low so that the motor efficiency becomes decreased. In other cases, when ferromagnetic materials with high permeability are used, these ferromagnetic materials will become more fragile than using ferromagnetic materials with lower permeability. Therefore, a good strategy is needed in designing the core material of the induction motor. This study was intended to provide an overview of the potential use of a composite material of Fe and ferromagnetic material that was made in the Graded Magnetostrictive Layers. This research was conducted using several studies of the results of research on the composite material of the magnet. The results of the study show that a composite material of Fe and ferromagnetic materials provided a great potential in applying to induction motors to increase power and efficiency of the motor.
