Abstract
A direct-current electric motor (an electrically powered machine) is a 3-pole brush-equipped direct-current electric motor which is provided with an armature (a rotor), a field element (a stator), a shaft, a commutator, a brush, a bracket, and an end plate. Of these, the armature (an armature) is provided with a dust core configured with a compressed powder compact formed of magnetic powder, and a coil buried in the dust core. On the other hand, the field element is provided with a field magnet which generates a magnetic flux, and a yoke housing which supports the field magnet and also functions as a housing.
