DESIGN AND IMPLEMENTATION OF A FAULT TOLERANT SCHEME FOR BLDC DRIVE

The design and implementation of a fault-tolerant scheme for a Brushless DC (BLDC) motor drive focuses on ensuring reliable operation even in the presence of faults such as inverter switch failures sensor malfunctions or winding defects. BLDC motors widely used in electric vehicles aerospace and industrial automation demand high reliability making fault tolerance essential. The scheme typically involves real-time fault detection isolation and compensation using redundant hardware sensorless control methods and reconfiguration techniques to maintain torque and speed with minimal performance loss. Implementation integrates a three-phase inverter microcontroller-based control and monitoring of current voltage and speed supported by algorithms for fault diagnosis and recovery. This approach enhances system safety reduces downtime and extends the operational life of the motor in mission-critical applications.
