Abstract

Provided is an identification method for use in an identification apparatus that identifies types of brushless DC motors. Each brushless DC motor includes a circuit board on which at least one terminal with a pull-up resistance incorporated therein is mounted. The pull-up resistances vary among multiple types of brushless DC motors. A power supply voltage is supplied from the identification apparatus to a brushless DC motor, a pull-up voltage value set by the pull-up resistance and outputted from the at least one terminal of the brushless DC motor is inputted to the identification apparatus, and the identification apparatus identifies the type of the brushless DC motor based on the pull-up voltage value.
