The importance of detecting failures and anomalies in electric motors reflects the improvement in the application of techniques used for maintenance on these machines. Thus, in the present work, a technique for detecting anomalies in the vibration of electric motors is proposed, based on the classification algorithm One-Class Support Vector Machine (OCSVM). An accelerometer device was used to capture the vibrations of an electric motor of 1.5 cv together with an electromagnetic brake system. In addition, a method for selecting the hyper-parameters of the algorithm was developed, obtaining a decision boundary that classified the operating data considered normal with a lower error rate than 5%
