Definitions
- the hand-held power tool according to the invention with the characterizing features of claim 1 has the advantage that its protective covers are in one piece or with multiple layers and can be applied to the parts to be encased by means of assembly line processes without any manual work. Simple technical means are suitable for this purpose, such as, for example, feed devices for the textile material of the protective sleeves and, for example, a punch and an ultrasound or laser welding device.
- the hand-held power tool according to the invention there is also the advantage of the smallest possible size with a long service life and high performance and better handiness. Due to the more streamlined shape of the engine parts and the good thermal conductivity of the protective covers, the cooling is improved and the increased service life and / or improved power output can thus be achieved.
- the rotor 13 is shown, which is covered by a protective sleeve 23 in the form of a tube. Whose ends are tied together in an end lacing 31 like sausages. Protrusions are separated by a weld cut between the rotor shaft 10 and the winding head 14. The outer surface of the hose can be gathered and pressed between the rotor laminated cores 22. So that for better heat conduction the cooling air flow 16 can get directly to the rotor core 22, the rotor 13 can be at least partially freed from the protective cover 23 on its outer diameter by grinding. The winding head 14 of the rotor 13 is then reliably protected against the abrasive particle effect.

Abstract
Pour une machine-outil à main, en particulier une meuleuse d'angle (1), muni d'un moteur électrique à ventilation intérieure (5), dont les bobinages enroulés à partir d'une multitude de spires de fil, en particulier le rotor (13) et chacune des bobines (18, 20) du stator (11), sont toujours entourés d'au moins une enveloppe protectrice (23), les mesures prises pour la protection contre la corrosion mécanique sont réduites par le fait que chaque enveloppe protectrice (23) est composée d'au moins deux coques partielles ou demi-coques (24, 25) assemblées entre elles.
