本発明は、電気自動車などの駆動に用いられるアウター
ロータ型モータのロータ取付方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for attaching a rotor to an outer rotor type motor used to drive an electric vehicle or the like.
本発明は、電気自動車などの車軸に固定して直接ホイル

性を高めた構造になっている。The present invention relates to an outer rotor type motor that is fixed to an axle of an electric vehicle or the like and rotates a tire directly via a wheel. More specifically, the rotor magnet is connected to the yoke via a pin, thereby increasing reliability against mechanical shock.

石の固定は、オーブンスペースも太き（とれるので余り
考える必要はなかった。Conventional electric vehicles replace the gasoline engine with a motor, and the motor is not fixed to the axle. Therefore, the motor had a large structure using alnico magnets as the rotor magnet, and its installation was easy. For this reason, fixing the rotor magnet took up a lot of oven space, so I didn't have to think about it too much.
前述の従来技術では、狭い空間にモータを配設するため

することによって、機械的ショックに対する信頼性を高
められ且つ精度も向上できることにある。In the above-mentioned conventional technology, since the motor is disposed in a narrow space, the axle becomes extremely large and heavy, making it difficult to move.
It had drawbacks such as lack of speed. The present invention is intended to solve these problems, and its purpose is to increase reliability against mechanical shock and improve precision by joining the rotor magnets to the yoke via pins. It's all about what you can do.

The yoke (yoke) is fixed to the rotor magnet 6 by the pin 7. The rotor magnet 6 is a 2-17 rare earth magnet bonded with epoxy resin. 9 and 6 have a structure in which adhesive is applied to the joining surfaces 12 and then joined together, and a part of the bottle 7 is caulked to be fixed. The rotor thus fixed is attached to the wheel 10 via the support frame 8. Reference numeral 5 denotes an armature, through which a pulse current is passed through a winding coil to rotate the rotor, thereby causing the vehicle to travel. During this rotation, extremely large torque is generated in the rotor. Rotor outer diameter 2101Il/+
For example, 7.5kg 1m at 48V100A.
You can get starting torque. Therefore, a structure like the bottle 7 can withstand such torque impact force and improve assembly accuracy.

簡単にし且つ信顛性を高められる効果がある。As described above, the present invention simplifies the structure of a drive motor for an electric vehicle and improves reliability by fixing the rotor magnet and yoke by drilling holes and performing adhesive and mechanical connection via a pin. It has the effect of increasing sex.
