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