The objective of this work was the development of a three-phase, six pole stepper motor with stator and rotor core built from Fe50%Ni alloy via powder metallurgy. The study involves analysis of the magnetic, electrical and mechanical properties, besides motor design and software simulation using finite elements. The Fe50%Ni alloy showed as result an electrical resistivity of 0.37 %%˙m, relative permeability of 946 and maximum induction of 0.93 T. In the computational simulation, with the application of 1 A current per phase, the required voltage was 2.88 V, which resulted in a power of 2.88 W. In this condition the stepper motor generates a torque of 6.81.10- 4 Nm with an air gap induction of 0.55 T.
