FIELD: engine technology.
SUBSTANCE: invention relates to the testing of DC electric machines. A method for diagnosing the technical condition of DC electric motors for land and water transport with electric propulsion includes measurement and amplitude-frequency-time analysis of the RMS deviation of vibration parameters performed using continuous wavelet transform, which makes it possible to record short-term vibration pulses in all operating modes of the diagnostic object from transient to steady.
EFFECT: improving the quality of controlling the technical condition of DC electric motors.
