Described is a stepper motor characterised in that it results from a matrix block manufactured out over a metal piece or any other material, where a work is performed with tools suitable to displace a central rotor of equal angular magnitudes generated by the division of a complete cycle into parts, thus the driving of the motor is performed step by step; said matrix block may be modular, since a motor may be assembled by attaching one or several matrixes, which form the central part of the motor, also placing the front (25) and rear (26) caps at the end portions thereof; for increasing the power of the motor it is only required to locate more modules in series adjacent the current modules, the power increase requiring the increase of the length of the central rotor as well as that of the rotating axis for controlling the forward motion of the motor. Each module is easily manufactured, without requiring special equipment and tools, the modular characteristic resulting attractive for the design of productive processes of high performance. The purpose of the present invention is to reduce manufacturing costs and increase the use of stepper motors widely used in the position control automation.
