The uses of industrial control systems and robotics are expanding rapidly due to their positive impact on costs and quality. This paper discusses aluminum electrolytic capacitors’ role as output filter capacitors to improve power quality in Brushless DC Motor (BLDC) controllers and drives. Aluminum electrolytic capacitors can be used to provide exacting drive voltage to motors. This, in turn, improves system reliability and performance. The paper reviews a test case using a 3-phase, 24V / 30 watt BLDC motor with a rated speed of 4000 RPM and rated torque of 0.072 N-m.
