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 operating a hand-held machine tool including a drive device, with a control device for actuating the drive device and at least two capacitive sensor elements operatively connected to the control device being provided. The method includes the following method steps of determining a first and second electrical charge of the first and second sensor element comparing the determined first electrical charge with a defined first threshold value and the determined second electrical charge with a defined second threshold value which differs from the first threshold value; enabling, via the control device, the actuation of the drive device when the first electrical charge is greater than the defined first threshold value and/or the second electrical charge is greater than the defined second threshold value. A machine tool for carrying out a method of this kind is also described.
