Title:
AXIAL ALIGNMENT APPARATUS AND METHOD OF MOTOR DYNAMOMETER
Document Type and Number:
WIPO Patent Application WO/2023/096001
Kind Code:
A1
Abstract:
An axial alignment apparatus of a motor dynamometer according to the present invention comprises: a sample material motor mounting jig on which a sample material motor is mounted; a Z-axis driving part for providing driving force in a vertical direction to the sample material motor mounting jig; a torque sensor mounted between the sample material motor and a load motor and detecting torque; a vibration sensor for detecting vibration of the sample material motor; and an axial alignment adjustment part for collecting a signal from at least one of the torque sensor and the vibration sensor, detecting an axial alignment state by performing Fourier conversion of the collected signal into a frequency area, and controlling the Z-axis driving part according to the detected axial alignment state.
