Abstract
An electric motor of an AC-operated, handheld power tool, with a stator that has multiple windings that are accommodated in a laminated stator core and are electrically insulated therefrom with basic insulation, in which stator a rotor is supported so as to be rotatable about an axis of rotation, wherein the rotor has a rotor shaft on which a laminated rotor core with a multiplicity of permanent magnets is held, which laminated rotor core is electrically insulated from the rotor shaft, characterized in that the stator is enclosed by a motor housing that is electrically insulated from the windings of the stator, and in that a supplementary electrical insulation is formed between the motor housing and the rotor shaft.
