摘要： The hand-held power tool has a tool socket to hold a tool. A motor is coupled to the tool socket in order to drive the tool socket. The motor is arranged in a housing. The housing has a holder that is provided with a mechanical lock for detachably coupling a battery pack, and with a power connection for electrically connecting the battery pack to the motor. A communication interface serves to transmit properties of the battery pack to a motor control unit. The motor control unit includes a soft start that accelerates the speed of the motor from a standstill to a target speed at a given rate, whereby the motor control unit controls the rate as a function of a property of the battery pack transmitted by the battery pack.
