This paper presents the design and implementation of a Stepper Motor using Nexys2 circuit board\nbased on a Xilinx Spartan 3E Field Programmable Gate Array (FPGA) device with VHDL code. The\nalgorithm implemented on FPGA allows a substantial decrease of the equivalent processing time\ndeveloped by different velocity controllers. The Stepper Speed control is achieved using VHDL\ncode, and the hardware digital circuit is designed for a programmable rotational stepper motor\nusing VHDL as a tool and FPGA as a target technology. The 50 MHZ provided by the starter kit is\ndivided to obtain the necessary delay time between the motor phases that ranges between 2 - 10\nm seconds. Though output selections, the direction of rotation of the stepper motor besides the\nmagnitude of the angle of movement and the rotation speed can be controlled. The major advantage\nof using reconfigurable hardware (FPGA) in implementing the Stepper Motor instead of a\ndiscrete digital component is that it makes modifications to the design easy and quick and also, the\ntotal design hence represents an embedded system (works without computer). The total programmable\nhardware design that controlled on the stepper motor movement, occupied an area\nthat did not exceed 12% of the chip resources.
