Abstract
The identification method according to an embodiment is used for an identification device for identifying the type of a brushless DC motor. A brushless DC motor includes an output terminal for outputting a signal. The output terminal is able to output a signal obtained by superimposing signal types. The signal resulting from the superimposition is different depending on the types of brushless DC motors. In the identification method, power is supplied to a brushless DC motor, and the signal resulting from the superimposition that is output from the output terminal of the brushless DC motor is input to an identification device. The signal resulting from the superimposition is separated into signal types, and the separated signals are used to identify the type of the brushless DC motor.
