| Abstract: | "Virtual ground" is a method often used in sensorless brushless DC(BLDC)controlling.A sensorless brushless DC controller implemented with the method of "virtual point" based on C8051f310 is introduced.In this method,simple circuits have been needed and enhanced the mechanic performances.IT has emphasized how to utilize the inner source of C8051f310 effectively.Meanwhile,the concept of Virtual Watch Dog Timer and the advanced three-step startup are proposed in software.Finally,the test results have been verified with kinds of BLDCs. |
