Abstract: An electric motor, in particular for a power tool, the electric motor having a stator with an inner opening for receiving a rotor. The inner opening has a diameter corresponding to an inner diameter of a stator, the stator having a series of pole teeth, which are each wound with a winding to form a coil. The winding is characterized by a reference diameter, a ratio of the reference diameter to the stator inner diameter multiplied by a number of pole teeth being greater than 0.3. Taking into account the internal resistance of an energy storage cell of an energy supply device of a maximum of 10 milliohms, the ratio of the diameters may be greater than 0.03 (milliohms)?1. Also provided is an electric motor, in particular for a power tool, a ratio being formed from a sum of total winding conductor cross sections and a free winding cross section, the ratio being multiplied by a number of pole teeth and the product being greater than 2.2.

Abstract: A method is provided for controlling a power tool (1) when a material (W) is being worked, including the steps: the rotational speed of a drive (20) of the power tool is set to a first value; a first temperature value is measured; the first temperature value is compared to a pre-specified threshold value; the rotational speed of the drive (20) is reduced from the first value to a second value if the first temperature value exceeds the pre-specified threshold value for a pre-specified first period of time; a second temperature value is measured; the second temperature value is compared to the pre-specified threshold value; and the rotational speed of the drive (20) is raised from the second value to the first value if the second temperature value has fallen below the pre-specified threshold value for a pre-specified second period of time.
