Abstract
The invention relates to a brush magnetic DC motor, in particular a novel AC-DC motor for hand-held bag-sewing machine. The novel AC-DC motor includes: an outer casing, a motor shaft, a front bearing, a rotor, a magnetic tile, a carbon brush holder, a commutator, a rectification assembly and a rear cover. The inner wall of the outer casing opposite to the position of the rotor is provided with a dual semi-annular motor plastic fixing block thereon. The fixing block is provided with a dual semi-annular motor inner casing thereon. The motor inner casing is provided with the magnetic tile thereon. The magnetic tile and the rotor have a gap therebetween. The rear cover is provided with the carbon brush holder, a filter capacitor and a rectifying tube thereon. The motor inner casing is a lock ring made of an iron sheet and tightly wraps the magnetic tile inside. The magnetic tile is composed of an upper sheet and a lower sheet which are close to semi-annular sheets. The carbon brush holder is provided with a carbon brush thereon. The brush magnetic DC motor of the invention has the advantages of reasonable structure, matched rotating speed, low temperature rise, excellent stability, low power consumption, simple technology and low production cost.
