    Abstract: In view of the limitations and deficiencies of current three-phase asynchronous motor fault diagnosis methods, based on the use of wavelet packet analysis to extract the characteristics of the motor fault signal, a fault identification model of asynchronous motor BP neural network based on bat-particle swarm and improved BP algorithm is proposed. The bat-particle swarm algorithm is used to optimize the structural parameters of the BP neural network, and the improved BP algorithm is used to train the BP neural network. The analysis of simulation results shows that the BP neural network model is used for fault identification of three-phase asynchronous motors, with fast identification speed, high accuracy and good reliability.
    Key words: asynchronous motor; wavelet packet analysis; bat-particle swarm algorithm; improved BP algorithm; fault identification
