The Research Of Hub-BLDC's Key Technology

The driver of the electrical motor is the key part of an electrical automobile. The driver's capability is the major factor, which influence the running performance of an electrical automobile. The driver must support the motor stably, reliably and efficiently and meet the requirement of start-up, running and braking.This dissertation is combined with the project practice of developing electrical automobile and do research on the key technologies of the BLDC's driver. The scope of research is protective measures, control strategy, feedback braking, soft-hardware realization and ABS function. The result of research is applied in the design and development of the driver. The developed driver performed good capability in platform test and on-road experiment.
