A DESIGN DIRECT-CURRENT (DC) MOTOR USING MATLAB

Electrical machine is a practical and dominant medium for achievement of productivity
improvement. DC motor is defined when a machine reverses the conversion process to
absorb energy in electrical form and reformat the energy to mechanical form on a
sustained basis. As the field of industrial application of direct current is very wide, DC
machine are produced both generators and motors, which suit for a large range of output
powers, voltages, speeds and other. Therefore, an adequate design in de motor is
essential in order to meet the industrial practitioners' requirement. This study basically
deals in designing de motor based upon the customer specification using interactive
computer software, MATLAB programming. The student is acted as the designer whom
is requested by the customer to design a de motor which produce correct simulation
outcomes in order to meet the desired specifications. The project mainly concentrates
on performing and formulating the required MATLAB programming added with C++
coding. The generated programs will demonstrate the plot-curves analysis of shunt
excited de motor design. An accurate de motor design is reflected from the curves
performed, whether it meet the performance specification or otherwise. MATLAB is
fully utilized as the main tool to complete this area of study. As the initial stage of the
study, iterative procedures have to be followed in designing the motor. The calculations
for all parameters in each design stages need to be performed using the correct
equations. The frame designation and units are referred to international standardization,
which is NEMA MG-1 Standard. In order to enhance understanding of the conceptual
design, literature review and theory is conducted concurrently with endeavor MATLAB
programming. As continuous from preliminary stage, the study then focuses on
application using MATLAB in order to perform the required analysis. Compared to
previous design of de motor, the NEMA frame designation and field winding
arrangement play significant roles in differentiating the desired plot-curve
representation.
