Motor using rotor including interior permanent magnet, and apparatus-driving-unit employing the same motor |
摘要 |
The motor includes the following elements: a stator-core having plural teeth, and a yoke that links the teeth, coils wound on the teeth in a concentrated winding form, and a rotor with interior permanent magnets. The rotor with interior permanent magnets includes the following elements: a rotor core having plural slits of which ends extend closely to the rotor circumference, permanent magnets positioned in the slits, non-magnetic-sections provided between the circumference of the rotor-core and respective ends of permanent magnets. This construction allows the motor to withstand persistently demagnetization, to be a smaller size with high efficiency, and to be manufactured in a highly efficient manner. The motor can be integrated as a driver into an apparatus driving unit.
