Abstract

Bürstenloser Elektromotor mit einem Außenläufer (Rotor), an welchem Permanentmagnetelement angeordnet sind, und einem Stator, welcher elektromagnetische Statorpole (7) aufweist, wobei die elektromagnetischen Statorpole (7) je einen Polfuß (17), einen Polzahn (12) und einen Polschuh (16) aus Eisenwerkstoffen aufweisen, und mit einer Isolationsschicht (11) um die Eisenelemente der Statorpole (7), und mit einer elektrischen Spulenwicklung, welche auf der Isolationsschicht (11) angeordnet ist, wobei die Polschuhe (16) im Querschnitt, vorzugsweise in Richtung ihrer Endbereiche, eine Freiformrundung (13) aufweisen und in einem Winkel > 90° zum Polzahn (12) nach außen weglaufend zu den Enden hin schmaler werden an der Unterseite der Polschuhe (16), da wo die Isolationsschicht (11) aufgebracht ist, wobei die Isolationsschicht (11) am Polschuh (16) sich an der Oberfläche (14) für die Spulenwicklungsaufnahme, also auf der prinzipiell gegenüberliegenden Oberfläche der Isolationsschicht (11) am Polschuh (16), rechtwinklig zum Polzahn (12) erstreckt.
