3 is a front view showing the permanent magnet 11 and the magnet holder 12 of FIG. 1, and FIG. 4 is a plan view showing the permanent magnet 11 and the magnet holder 12 of FIG. The magnet holder 12 has a plate shape. A recess 121 into which the permanent magnet 11 is fitted is formed on the radially inner side surface of the magnet holder 12. In this example, the radially inner side surface of the magnet holder 12 is a magnet pasting surface. The magnet holder 12 has a screw hole 122 extending in the axial direction. Bolts 14 are inserted into the screw holes 122. By inserting the bolt 14 into the reamer hole 133 and the screw hole 122, the magnet holder 12 is fixed to the base 131.
この例では、１つの磁石保持体１２に１つのねじ孔１２２が形成された構成について説明するが、１つの磁石保持体１２に複数のねじ孔１２２が形成されてもよい。また、この例では、１つの磁石保持体１２に１つの永久磁石１１が取り付けられる構成について説明するが、１つの磁石保持体１２に複数の永久磁石１１が取り付けられる構成であってもよい。
In this example, a configuration in which one screw hole 122 is formed in one magnet holder 12 will be described, but a plurality of screw holes 122 may be formed in one magnet holder 12. In this example, a configuration in which one permanent magnet 11 is attached to one magnet holder 12 will be described, but a configuration in which a plurality of permanent magnets 11 are attached to one magnet holder 12 may be used.
次に、アウターロータ型電動機１の製造方法について説明する。まず、磁石保持体機械加工工程を行う。磁石保持体機械加工工程では、磁石保持体１２に凹部１２１を形成する。磁石保持体１２が基部１３１に固定される前に、磁石保持体１２に凹部１２１が形成されるので、磁石保持体１２の磁石貼付面を容易に機械加工することができる。
Next, a method for manufacturing the outer rotor type electric motor 1 will be described. First, a magnet holder machining process is performed. In the magnet holder machining step, the recess 121 is formed in the magnet holder 12. Since the concave portion 121 is formed in the magnet holder 12 before the magnet holder 12 is fixed to the base 131, the magnet sticking surface of the magnet holder 12 can be easily machined.
磁石保持体機械加工工程の後、磁石貼付工程を行う。磁石貼付工程では、凹部１２１に永久磁石１１を取り付ける。また、磁石貼付工程では、永久磁石１１は、接着剤を用いて磁石保持体１２に対して固定される。磁石保持体１２が基部１３１に固定される前に、永久磁石１１が磁石保持体１２に固定されるので、永久磁石１１を磁石保持体１２に容易に固定することができる。
After the magnet holder machining process, the magnet sticking process is performed. In the magnet sticking step, the permanent magnet 11 is attached to the recess 121. In the magnet sticking step, the permanent magnet 11 is fixed to the magnet holder 12 using an adhesive. Since the permanent magnet 11 is fixed to the magnet holder 12 before the magnet holder 12 is fixed to the base 131, the permanent magnet 11 can be easily fixed to the magnet holder 12.
磁石貼付工程の後、磁石保持体組付工程を行う。磁石保持体組付工程では、まず、磁石保持体１２を保持体取付面１３４に接触させた状態で、磁石保持体１２を位置決め部１３２に径方向に当てる。これにより、磁石保持体１２の径方向についての位置が決められる。その後、磁石保持体組付工程では、リーマ孔１３３およびねじ孔１２２にボルト１４を挿入して、磁石保持体１２を基部１３１に対して固定する。以上により、アウターロータ型電動機１の製造方法が終了する。
After the magnet pasting process, the magnet holder assembly process is performed. In the magnet holder assembly step, first, the magnet holder 12 is applied to the positioning portion 132 in the radial direction in a state where the magnet holder 12 is in contact with the holder attachment surface 134. Thereby, the position of the magnet holder 12 in the radial direction is determined. Thereafter, in the magnet holder assembly step, the bolts 14 are inserted into the reamer holes 133 and the screw holes 122 to fix the magnet holder 12 to the base 131. Thus, the method for manufacturing the outer rotor type electric motor 1 is completed.

Therefore, a magnet sticking that is a surface to which the permanent magnet 11 is attached in the magnet holder 12 is provided. Surface machining is facilitated, and as a result, manufacturing efficiency can be improved. Further, since the permanent magnet 11 can be easily fixed to the magnet holder 12, the manufacturing efficiency can be further improved.
また、ロータヨーク１３は、基部１３１に設けられ磁石保持体１２が径方向に当たることによって径方向についての磁石保持体１２の位置が決められる位置決め部１３２を有しているので、磁石保持体１２を位置決め部１３２に当てることによって、磁石保持体１２の径方向についての位置決めを容易に行うことができる。その結果、アウターロータ型電動機１の製造効率を向上させることができる。
Further, the rotor yoke 13 has a positioning portion 132 that is provided on the base portion 131 and determines the position of the magnet holder 12 in the radial direction when the magnet holder 12 hits in the radial direction. By contacting the portion 132, the magnet holder 12 can be easily positioned in the radial direction.
