English: stepper motor schematics
Deutsch: Schrittmotor Anschluss-Schemata; links ein bipolarer Motor aus einem Drucker, Spulenwiderstand 7 Ohm; rechts ein unipolarer Motor mit einem Spulenwiderstand von 140 Ohm aus einem Diskettenlaufwerk. Beide Motoren haben eine Kantenlänge von 40 mm. Bipolare Anschlussweise erfordert je eine H-Brücke pro Wicklung; unipolarer Betrieb erfordert lediglich zwei Schalttransistoren pro Doppelspule. Unipolare Motoren wie der abgebildete lassen sich auch bipolar betreiben, indem die Mittelanzapfungen unbeschaltet bleben.
