DC Motor control circuits-直流电动 DC Motor control circuits, Notes:Here,S1 and S2 are normally open,push to close ,press button swithches.The diodes can be red or green and are there only to indicate direction.
The present invention relates generally to direct current motor control circuits of the type in which alternating current from a source is rectified and applied to the motor through a phase controlled bridge circuit to control the effective voltage thereof and more particularly to such circuits which...
摘要: PROBLEM TO BE SOLVED: To prevent the misalignment of a print head by providing a means that short-circuits the part between armature coil winding terminals for applying a DC drive voltage to a DC motor, when the motor is not being driven....
