Die Anzahl der Spulen 4 des Stators 2 stehen zur Anzahl der Permanentmagnete 3 auf dem Rotor 1 vorzugsweise im Verhältnis von drei Spulen 4 zu vier Permanentmagneten 3 oder einem ganzzahligen Vielfachen davon, so z . B. im Verhältnis 9:12 oder 12:16. Andere Verhältnisse sind denkbar. Auf der dem Stator 2 abgewandten Seite der Scheibe 1 kann eine weitere Scheibe 7 und/oder eine Ringscheibe 8 aus einem magnetischen Werkstoff angeordnet sein. Durch die Scheibe 7 bzw. Ringscheibe 8 wird ein starker magnetischer Rückschluss geschaffen ist. Die Scheibe 7 und die Ringscheibe 8 sind zur Welle 5 magnetisch isoliert. The number of coils 4 of the stator 2 are the number of permanent magnets 3 on the rotor 1 preferably in the ratio of three coils 4 to four permanent magnets 3 or an integral multiple thereof, such. In the ratio 9:12 or 12:16. Other conditions are conceivable. On the side facing away from the stator 2 of the disc 1, a further disc 7 and / or an annular disc 8 may be arranged from a magnetic material. Through the disc 7 or washer 8 is a strong magnetic inference is created. The disc 7 and the annular disc 8 are magnetically isolated from the shaft 5.
Die Spule 4 kann sehr leicht auf den Spulenkern aufgewickelt werden. Die Verbindung der Spulen 4 untereinander ist ebenfalls unproblematisch. Bei gewünschten konstruktiven Detaillösungen können die Spulen 4 auch aus Teilspulen bestehen . The coil 4 can be wound up very easily on the spool core. The connection of the coil 4 with each other is also no problem. For desired structural detail solutions, the coils 4 may also consist of partial coils.
