Design A Direct-Current (DC) Motor Using MATLAB

This paper present a study on designing
dc motor based upon performance specification
given by the customer using interactive computer
software, MATLAB programming. The student is
acted as the designer whom is requested by the
customer to design a dc motor which produces
correct simulation outcomes to allow assessment
with regard to desired specifications. The project
mainly focuses on performing and formulating the
required MATLAB programming, added with
C++ coding. The generated programs will
demonstrate the plot-curves analysis of shunt
excited dc motor design. An accurate design is
reflected from the curves performed, whether it
meet the performance specification or otherwise.
Iterative step-by-step procedures have been
followed as basic guideline throughout the
designing process. The frame designation and
units are referred to international
standardization, which is NEMA MG-1 Standard.
All the parameters in every design stages are
calculated using correct equations and the values
are being used in MATLAB as data input of the
programming. The MATLAB programs are
mainly comprise of specifications given by the
customer, set of commands and relevant
functions, equations for performing data input
and also added in small portion of C++ coding.
Finally, the analysis part where the plot-curves of
speed-torque, speed-armature current, speedoutput
power and speed-efficiency are successfully
generated using MATLAB.
