Abstract
The present invention provides a molded motor in which the axial center of an inserted body can easily be aligned with the axial center of the rotor of the mold motor. The molded motor of the present invention is provided with: a stator 30 having a stator core 31 laminated from a plurality of layers of thin metal coldrolled steel plate and stator coils 8 mounted in the stator core 30; a rotor 2 rotatably disposed inside the stator 30; and a molded main body 4 made of resin which covers the stator 30 and has a receiving portion 17 in which an annulus 16 is received, wherein guide portions 34 are formed in the cold-rolled steel plate closest to the annulus 16 to align the axial center of the annulus 16 with the axial center of the rotor 2.
