... brushless DC motor (BLDC)-driven water pumping system with a bidirectional power flow control. The system with bidirectional power flow allows driving the pump at full proportions uninterruptedly irrespective of the weather conditions and feeding a grid when water pumping is not required. Design...

... brushless DC motor A three-phase BLDC motor requires three hall sensors to detect the rotor’s position. These sensors are placed 120° from each other and it provides the required digital signals (high/low) for the controller to determine the rotor position in intervals of 60 electrical degrees...
