PURPOSE: A molded-type motor is provided to reduce resin required for a mold by removing a device mounting area in a substrate. CONSTITUTION: In a molded-type motor, a stator assembly(10) comprises a hollow body(10'). The hollow body is formed by molding a core, a coil, and an assembly unit. The hollow body is molded by a resin. A bearing is installed in the hollow both sides entrance of the stator assembly. A rotor(20) is inserted into the hollow of the stator assembly. The rotor is supported in the bearing. An insulator surrounds the core. A coil is wound around the teeth of the core. A device controls a current which is applied to the coil. The current controls the driving and rotation speed of the rotor. A sensor senses the magnetic pole of the rotor. |
