Parameter Identification of BLDC Motor Using Electromechanical Tests and Recursive Least-Squares Algorithm: Experimental Validation

In this article, the parameter identification of a brushless DC motor (BLDC) is presented. The approach here presented based on direct considering three-phase line-to-line voltage electromagnetic torque as function electric currents and rotor speed. estimation divided into two stages. First, electrical parameters are estimated by well-known no-load tests. Consequently, mechanical performed using recursive Least Square Algorithm. proposed validated comparing model responses to real time responses. Additionally, design, digital simulation implementation PI speed controller, model, validate proposal here.
