The embodiment of the utility model relates to a brushless motor commutation circuit and device. The brushless motor commutation circuit comprises a brushless motor control module, a commutation signal generation module, a commutation follow current logic conversion module and an enabling follow current synchronization signal module, the output end of the brushless motor control module is connected with the input end of the commutation signal generation module, and the input and output ends are connected to the output end of the commutation follow current logic conversion module; the input end of the commutation signal generation module is connected to the first input end of the commutation follow current logic conversion module; the second input end of the commutation freewheeling logic conversion module is connected to the enabling freewheeling synchronization signal module. An enabling freewheeling synchronizing signal module and a commutation freewheeling logic conversion module are added, so that a trans
