The purpose of this research is to develop the linear induction - synchronous hybrid motor with a novel construction for practical use. In recent years, as for the adoption of the electric motors in the fields of industrial world, high stable alternating-current motor represented in the induction motor and the synchronous motor becomes the main stream. Though there are complementary relations between the induction motor and the synchronous motor in terms of advantages and disadvantages, it was difficult to hybridize them by existing structure because of the decline of the efficiency for operation. From the standpoint of the linear motors with construction, we proposed that the U-shaped linear hybrid motor that made us operate the induction motor in parallel with the synchronous motor on the same winding coil. A detailed examination was done for practical use.First as a fundamental investigation, we verified that the undesirable magnetic attraction was offset by its symmetrical construc … More tion, the space harmonics was reduced effectively by an adoption of split pole on the side of field winding with the concept of pulse width modulation, the effective inductive thrust for self starting and hunting prevention was obtained by hybridizing synchronous actions to the inductive actions.Furthermore, we investigated not only the static characteristics, but also the transient characteristics by the running experiment. As a consequence, we have succeeded to confirm the effectiveness of the proposed motor achieved to be synchronized with less vibration and shorter range.In future, it can be thought that the development of the linear hybrid motor including several characteristics proceed more.Since the characteristic ratio of each motor depends on the characteristics on the whole of the motor, as for getting requested characteristics with this hybrid motor, it is thought to be very effective that proposed motor has U-shaped construction which is independent on the secondary side part respectively.

本研究的目的是开发具有新颖结构的实用化线性感应同步混合电机。近年来，就电机在工业领域的采用而言，以感应电机和同步电机为代表的高稳定性交流电机成为主流。虽然感应电机和同步电机在优缺点上存在互补关系，但由于运行效率的下降，现有结构很难将它们混合。从线性电机结构的角度来看，我们提出了U形线性混合电机，使我们能够在同一绕组线圈上并联运行感应电机和同步电机。对实际使用进行了详细的检查。首先作为基础研究，我们验证了其对称结构抵消了不良磁引力，采用脉宽调制概念的励磁绕组侧分极有效降低了空间谐波，通过将同步动作与感应线圈混合，获得了有效的感应推力，用于自启动和防振荡。 此外，我们不仅研究了静态特性，还通过运行实验研究了瞬态特性。结果，我们成功地证实了所提出的电机的有效性，以实现更少振动和更短范围的同步。将来，可以认为，包括多种特性的线性混合电机的开发将更加深入。由于每个电机的特性比取决于整个电机的特性，因此为了获得该混合电机所要求的特性，我们认为所提出的电机具有U形结构是非常有效的，该结构是 分别独立于次级侧部分。较少的
