A Brushless Direct Current (BLDC) motor has been widely used due to the high efficiency, durability, easy maintenance, and winding dynamically faster than a brushed direct current motor. The objectives of this research are to investigate and analyze the efficiency of function and the response of BLDC motor in the neighbor of speed response. The simulation of BLDC motor was established in the mathematical model as the state space model which was in the first order of differential equations as well as the analysis in time domain and in the signal with Multi MIMO simulation. The investigation in the behavior of BLDC motor is classified to two cases, load motor and non-load motor, with testing for BLDC motor, rated voltage (24 V), rotational speed (3,000 rmp). The simulation results showed that the load supply for motor resulted in the decrease in the rotational speed but the increase in the current. Therefore, the load supplied for BLDC motor affects the motor's response behavior in term of rotational speed decreasing and current increasing.
