Description

technical field [0001] The invention relates to the field of textile equipment, in particular to a flat knitting machine electromagnet state detection circuit. Background technique [0002] At present, computerized flat knitting machines have gradually become general-purpose equipment in the field of knitting technology, and computerized flat knitting machines need to use various electromagnets, such as needle selection electromagnets, triangle electromagnets, yarn feeder electromagnets, etc., to select shuttles, needles, etc. Various operations. The head electric controller of the computerized flat knitting machine mainly controls the needle selection electromagnet, triangle electromagnet, yarn feeder electromagnet and stepping motor, etc. These devices have auxiliary protection circuits such as special over-current protection circuits, but only these cannot Fully guarantee the normal operation of the flat knitting machine system. For example, if the electromagnet of the y...
