Hardware Implementation of BLDC Motor Diagnosis

摘要

In today's automotive applications the usage of BLDC (Brushless DC) motors is becoming very popular because of its advantages over the DC motors. For automotive applications the permanent fault diagnosis and protection of the BLDC motor is mandatory. This paper presents a concept for extensive diagnosis implementation for the fault conditions of a BLDC motor. The implementation is done using hardware circuits which can be easily integrated in the BLDC motor control ASIC (Application Specific Integrated Circuit).
