The working theory of RS-328B resistance-wire winding machine for the manufacturing of compact spiral coils is to reel the coil to the payoff with a brake gear, guide the resistance wire to precision spinning by the wire carrier, and twine the wire around the core axle by an adjustable speed rotary device. The inside diameter of the coil is decided by the external diameter of the core axle, which can be altered free and controlled by coder and electronic counter. The length's analogue of the resistance wire could be set and amended in the counter to achieve length control. As long as the wire comes to the preset length, it would be cut through displacement or electromagnet. The other counter of the machine records and controls the quantities of the spiral coils. The frequency converter is employed in adjusting the rotational rate of the core axle. The production capacity is 2500 PCs/8h.
