Abstract
The invention is based on a hand power tool having an electric motor () located in a housing (), via which an insertable tool () situated in a tool mount () is capable of being driven in a rotating manner, and having a safety device () with which a characteristic value for an occurrence of uncontrolled blockage of the insertable tool () can be detected via a sensor unit (), and the movement of the housing () can be decelerated. It is proposed that the safety device () is formed at least partially by a motor control unit (), via which the electric motor () can be actively decelerated when an occurrence of uncontrolled blockage of the insertable tool () is detected.
