Detection of ventilation diagnosis

The use of power tools (electric impact drills, angle grinders, cordless screwdrivers, etc.) can be found in the construction industry. Faults of electric power tools can be dangerous for employees’ health. Condition monitoring enables early detection of machine faults. Highly effective diagnosis techniques of electric power tools can decrease the number of accidents and economical losses. For these reasons investigation of fault diagnosis of electric power tools is essential. The development of new methods and techniques of fault diagnosis is profitable. Fault diagnosis techniques can be focused on various parts of equipment for example bearings, ventilation, gears, brushes, stator faults, rotor faults, shaft, etc. The development of fault diagnosis techniques is also related to signal analysis for example: acoustic and vibration signals.
