Modelagem e controle de velocidade do motor CC sem escovas aplicado a veículos elétricos

Abstract

In this paper we present the motor speed control method Brushless through vector control and a brief demonstration of the speed control using the control by hysteresis. The topology of the electronic three-phase inverter driver applicable to motor Brushless DC (BLDC) is displayed. Brushless motors are widely used in electric vehicles and stand out for their high performance and low maintenance, making it the best choice for this application. A mathematical modeling of ideal Brushless motor besides the main connection settings and electronic control strategy. Modeling is obtained from the theoretical characteristic curve of torque X speed and efficiency X torque of an existing prototype.
