Porro et retrorsum rotatione DC motor controller, motor controller clockwise et counterclockwise. Motricium est clockwise gyrationis motricium est, et motor Rotate counterclockwise est reverso motricium. Et reversing imperium circuitu et principle analysis ut consequi motor moderatoris et reversing, quamdiu duo tempus switch connectatur motor controller trium-phase potentia copia Circuit potest consequi finis inverter. Sunt duo modi hoc facere: unum est armature vicissim modum, nimirum non mutare agri coruscans terminum voltage, in mutantur initus intentione a armatione curvis ad vicissim motricium controller. 2 it is reverse excitation winding connection, that is, the armature winding end voltage unchanged, by changing the excitation winding end voltage to adjust the direction of the motor controller, when the two motor controller voltage change at the same time, the direction of rotation of motor controller stays the same.
