Electric motor for a handheld power tool

An electric motor of an AC-operated handheld power tool, the electric motor comprising:

• a stator that has a plurality of windings that are accommodated in a laminated stator core and are electrically insulated therefrom with insulation;
• and
• a rotor supported in the stator so as to be rotatable about an axis of rotation, the rotor having a rotor shaft on which a laminated rotor core with at least two permanent magnets is held,
• wherein the laminated rotor core is electrically insulated from the rotor shaft,
• wherein the stator is enclosed by a motor housing that is electrically insulated from the windings of the stator,
• wherein a supplementary electrical insulation is formed between the motor housing and the rotor shaft,
• wherein the supplementary electrical insulation includes an end cap that delimits the motor housing in an axial direction, and
• wherein a mounting flange, in which a part of a position sensor is accommodated for determining a rotational position of the rotor shaft, is formed in the end cap.
