A variable speed motor includes a motor body having an axis, and a plurality of coil mounting parts that extend radially and that are angularly spaced apart relative to the axis. A run coil is mounted on the coil mounting parts. A starting winding includes first, second and third speed-changing coils mounted on the coil mounting parts, a set of first taps provided respectively on two coil terminals of the first speed-changing coil, a set of second taps provided respectively on two coil terminals of the second speed-changing coil, and a set of third taps provided respectively on two coil terminals of the third speed-changing coil. Each of the first, second and third speed-changing coils spans an angular length relative to the axis that is substantially equal to that spanned by the run coil.
