ENHANCEMENT OF DYNAMIC PERFORMANCE OF BRUSH LESS DC MOTOR DRIVE

Growing of industry and increasing demand in consumer load/distribution side place a new demand in mechanism connected with electrical motors. This is leading to different problems in working operations due to fast dynamic and instability. The stability of the system is essential to work at desired set target but due to non-linearity caused by a motor frequently reduces stability which reduces control ability to maintain speed/position at set points. BLDC motors are widely used in industries because high efficiency, low cost, roughest construction, long operating life noise less operation but the problem arises in BLDC motors are speed controlling by using sensor and senseless controllers and large torque ripples and torque oscillations. This paper presents assessment and evolution of the BLDC motor by providing proper voltage controller methods (back emf controller method) and analysis has done in MATLB/SIMULINK software. Therefore the parameters of the BLDC motor analyzed and compered with BLDC motor drive without any controller.
