Abstract (en)

[origin: WO2022178771A1] The present invention relates to a power tool adapted to produce a notification to a user. The power tool comprises a sensor configured to sense a fault condition of the power tool; a motor driving circuit connected to the sensor, and configured to provide a motor driving signal based on the fault condition of the power tool; and a motor connected to the motor driving circuit and adapted to be driven by the motor driving signal from the motor driving circuit to produce the notification. The notification is in the form of an audible sound and/or a perceivable vibration via which the user is notified about the fault condition.
