Magnetic characterization of the stator core of a high-speed motor made of an ultrathin electrical steel sheet using the magnetic property evaluation system AIP Advances 8, 047603 (2018) Abstract. In this study, radial BLDC motor is the object of research. The study focused on stator core material to improve electric motor performance by replacing the laminate material with a composite material powder. The use of composite material powder for wound core material is to simplify the manufacturing process with efficiency equal or close. Wound core material was tested by using VSM, the test is intended to determine electromagnetic properties of materials. The process of preparation of the sample is done by using pressure variations. The result of electromagnetic properties of the material is in the form of remanence, permeability, and coercivity. The result of the electromagnetic character of the material is then used as input material properties of the core windings for simulation. From the simulation results obtained performance electric motors. The effect of using different wound core to the efficiency of the motor is then compared. From the study, it can be concluded that by replacing the core material obtained efficiency of the motor windings are nearing a conventional motor. Excellence wound core materials that use composite powder is the ease in the manufacturing process.
