Abstract
A motor malfunction monitoring device for monitoring a malfunction of a drive motor, includes: vibration sensors for detecting for one or more components of the drive motor transverse vibration in a direction parallel to a mounting plane of the drive motor and perpendicular to a longitudinal direction of the drive motor or longitudinal vibration in a direction perpendicular to both the mounting plane and the longitudinal direction of the drive motor; a voltage sensor for detecting a voltage of the drive motor or a current sensor for detecting a current of the drive motor; and a data storage storing a database of normal operation spectrums of one of the transverse vibration or the longitudinal vibration during a normal operation of the drive motor, and of one of the voltage or the current during a normal operation of the drive motor.
