Small-sized direct-current motor |
| abstract |
ABSTRACT A small-sized direct-current motor in which a PTC thermistor made of a BaTiO3 ceramic material with the ratio V.beta./? 25 of the withstanding voltage V.beta. to the ordinary-temperature resistivity ?25 in a range of from 7 to 20 is connected to an armature coil in series and is disposed within a motor housing. |
