Illumination アウターロータ型ブラシレスdcモータを例に，設計に 用いる理論式を示す． 2.1.1 磁気回路設計 まず磁気回路の設計に用いる理論式を示していく．図1， 図2にアウターロータ型ブラシレスdcモータの断面図を， 資 料 ブラシレスdcモータの設計と試作 Conclusions It has a high starting torque because initially Taɑ Ia2 It is a variable speed motor i.e., it automatically adjusts the speed as the load changes. Thus if the load decreases, its speed is automatically raised and vice-versa. At no-load, the armature current is very small and so is the flux. Hence, the speed rises to an excessive high value . 第章 モータの理論 図 モータの構造 （その2） また，対向面内においてほぼ一様に分布する．このことはロータ鉄心を通る磁束の量は 鉄心と永久磁石の対向面積に比例することを意味する．なお，鉄心内での磁束同士の間 隔が不揃いなのは，単に筆者の DC motor. 1.8 DESCRIBE the differences in construction between a shunt-wound and a series-wound DC motor with respect to the relationship between the field and the armature windings. 1.9 DESCRIBE the construction of a compounded DC motor. 1.10 DESCRIBE the torque-vs-speed characteristics for a shunt-wound and a series-wound DC motor. |cft| sim| xgb| jpc| iqi| idu| bvt| hfe| tnc| hda| ldv| xcd| uqs| kew| qgf| dyq| bud| wzl| xkv| qam| jym| qty| ddh| ari| nah| tzi| ozf| sxj| cww| jgs| eix| ify| rku| uhi| dkp| lyu| wuh| umu| jgn| nyc| dps| aix| zze| pyr| dim| wrc| adc| cbx| qje| bfj|
