A stator core includes a laminated core member and a single-piece insulating layer. The laminated core member includes: a central ring portion defining an axis, and having first top and first bottom sides disposed opposite to each other, and an outer periphery extending from the first top side to the first bottom side; and at least two coil mounting portions extending radially and outwardly from the central ring portion, and angularly spaced apart relative to the axis. Each of the coil mounting portions has a second top side extending contiguously from the first top side, a second bottom side extending contiguously from the first bottom side, and a pair of coil winding surfaces extending from the second top side to the second bottom side. The insulating layer covers the top and bottom sides, the coil winding surfaces, and segments of the outer periphery between the coil mounting portions.
