Title:
IDENTIFICATION METHOD FOR IDENTIFYING TYPES OF BRUSHLESS DC MOTORS, IDENTIFICATION DEVICE, AND BRUSHLESS DC MOTOR
Document Type and Number:
WIPO Patent Application WO/2019/181471
Kind Code:
A1
Abstract:
This identification method identifies information about a brushless DC motor, which is output from the brushless DC motor, and is used in an identification device. The identification method comprises: supplying a power supply voltage to the brushless DC motor from the identification device via a power supply line; upon receiving the supply of the power supply voltage, rotating the brushless DC motor according to a PWM signal output from a drive circuit for the brushless DC motor and measuring reaching time until a drive current flowing through the power supply line in association with the rotation of the brushless DC motor reaches a threshold value; and identifying information about the brushless DC motor on the basis of the reaching time.
