sensorlessdrive: Sensorless Drive Faults Detection Data

Description

These data are the results of a sensorless drive diagnosis procedure. Features are extracted from the electric current drive signals. The drive has intact and defective components. This results in 11 different classes with different conditions. Each condition has been measured several times by 12 different operating conditions, this means by different speeds, load moments and load forces. The current signals are measured with a current probe and an oscilloscope on two phases. The original dataset contains 49 features, however, here only 3 are used, that is, features 5, 7 and 11. First class (1) are the healthy drives and the rest are the drives with fault components.

Usage

data(sensorlessdrive)

Format

sensorlessdrive is a data frame with 58509 cases (rows) and 4 variables (columns) named:

1. V5 continuous.

2. V7 continuous.

3. V11 continuous.

4. Class discrete 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or 11.
