This paper presents modeling, performance evaluation, and comparative analysis of speed performance of brushless
DC motor (BLDCM) by using digital controllers. Speed performance analysis is carried out by using time response specifications
which are useful for determining the effectiveness of the digital controllers. The wide spread of BLDCM in many areas due to
the advantages of BLDCM over the conventional widely used motors such as induction motor and brushed DC motor.
Advantages of BLDCM include higher efficiency, lower maintenance, longer life, reduced losses, single excitation, etc.
Controllers are used to improve the transient and steady state speed response of the BLDCM.
