ASSESSMENT OF THE OPERATING CHARACTERISTICS OF BRUSHLESS DC MOTORS [PDF]
Journal of Energy TechnologyThis paper presents the operating characteristics of brushless DC motors (BLDC) obtained via analytical, numerical, and simulation software, enabling steady-state and transient characteristics of a motor to be computed. Based on the catalogue data from the producer, Moog, a motor is simulated in a closed-loop control system fed by a voltage inverter ...
