Abstract
Provided are a winding device and a motor. A nozzle that feeds out a coil has: a nozzle hole from which the coil is fed out; an inner-diameter round chamfered part formed on an opening edge of a tip of the nozzle; an outer-diameter round chamfered part formed on the outer peripheral edge of the tip of the nozzle. When the wire diameter of the coil is defined as Φc, the inner diameter of the nozzle hole is defined as Φin, the radius of curvature of the inner-diameter round chamfered part is defined as Rin, and the radius of curvature of the outer-diameter round chamfered part is defined as Rout, they satisfy 1.2Φc≤Φin≤1.4Φc, 0.5Φc≤Rin≤Φc, and 0.25Φc≤Rout≤0.5Φc.
