Title:
IDENTIFICATION METHOD AND IDENTIFICATION DEVICE FOR IDENTIFYING TYPE OF BRUSHLESS DC MOTOR
Document Type and Number:
WIPO Patent Application WO/2019/189166
Kind Code:
A1
Abstract:
An exemplary identification method according to the present disclosure is used for an identification device that identifies the type of a brushless DC motor. Output response characteristics of the brushless DC motor vary from one type to another of a plurality of brushless DC motors. This method includes: supplying a power supply voltage from the identification device to the brushless DC motor via a power supply line; and identifying the type of the brushless DC motor on the basis of a driving current flowing through the power supply line in accordance with the rotational speed of the brushless DC motor which is accelerated toward a first speed in response to a first speed command value.
