Abstract: A portable power tool includes a motor housing (22a, 22b, 22c, 22d, 68) and a housing cover (26a, 26b, 26c, 26d, 72) that is attached to the motor housing (22a, 22b, 22c, 22d, 68). The portable power tool includes insulation (44a, 44b, 44c, 44d, 70a, 70b) adjacent to the motor housing (22a, 22b, 22c, 22d, 68) and the housing cover (26a, 26b, 26c, 26d, 72), which are guided through a guide (50a, 50b, 50c, 50d, 52a, 52b, 52d, 92) in the direction toward the motor housing (22a, 22b, 22c, 22d, 68) and/or the housing cover (26a, 26b, 26c, 26d, 72).

Abstract: The present invention relates to a portable power tool with a motor housing (22a, 22b, 22c, 22d, 68) and a housing cover (26a, 26b, 26c, 26d, 72) that is attached to the motor housing (22a, 22b, 22c, 22d, 68). It is provided that the portable power tool includes insulation means (44a, 44b, 44c, 44d, 70a, 70b) adjacent to the motor housing (22a, 22b, 22c, 22d, 68) and the housing cover (26a, 26b, 26c, 26d, 72), which are guided through a guide means (50a, 50b, 50c, 50d, 52a, 52b, 52d, 92) in the direction toward the motor housing (22a, 22b, 22c, 22d, 68) and/or the housing cover (26a, 26b, 26c, 26d, 72).

Abstract: The armature (1) for high-speed electric motors force-ventilated in air containing abrasive dust, in particular in electric tools including right angle grinders, has windings which are laid in slots (7) of an armature laminate stack (5), and are held down in the slots (7) by elongated, elastic slot seals (15), and forth winding overhangs (9, 11) on the end faces of the armature. To increase the strength of the armature winding, the resistance to cooling air containing abrasive dust, and to improve the cooling, the slot seals (15) project over the slots (7), follow the contour of the winding overhangs (9, 11), in particular along surface lines, in the armature longitudinal direction, extend up to the end faces of the armature (1), and their ends are secured there by a ring (19) or cord winding (17).
