Title:
IDENTIFICATION METHOD FOR IDENTIFYING TYPE OF BRUSHLESS DC MOTOR, IDENTIFICATION DEVICE, AND BRUSHLESS DC MOTOR
Document Type and Number:
WIPO Patent Application WO/2019/107156
Kind Code:
A1
Abstract:
[Problem] To provide an identification method of a brushless DC motor capable of identifying information relating to a brushless DC motor without specifically performing a handshake. [Solution] The identification method of the present disclosure includes: supplying an input voltage from an identification device 100 via a power supply line to a brushless DC motor 200 having at least one resistance element 251 connected between the power supply line and a GND line, an inverter 230 that drives a motor, and a switching circuit 270 that switches the power supply line and an inverter 230 between being connected and not connected; disconnecting the inverter from the power supply line using the switching circuit; reading a resistance value of the at least one resistance element in a state with driving of the inverter stopped; and identifying information relating to the brushless DC motor based on the read resistance value of the at least one resistance element.
