本発明は永久磁石回転電機に係り、特にスロットリップ
ルの少ない高性能回転電機を量産するのに好適な着磁装
置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a permanent magnet rotating electrical machine, and particularly to a magnetizing device suitable for mass producing high-performance rotating electrical machines with little slot ripple.
従来、永久磁石回転電機の固定子、または回転子に組み
込まれた永久磁石を着磁する際には、被着磁物の形状２
寸法に合わせた着磁ヨークを製作し、１回または２回程
度、着磁ヨークに磁束を発生する為のコイルに電流を流
し着磁していた。Conventionally, when magnetizing a permanent magnet incorporated in the stator or rotor of a permanent magnet rotating electric machine, the shape of the object to be magnetized is 2.
A magnetizing yoke was manufactured according to the dimensions, and the magnetizing yoke was magnetized by passing current through a coil for generating magnetic flux once or twice.
第３．４図に従来の着磁装置の例を示す。Figure 3.4 shows an example of a conventional magnetizing device.

着磁を実施する際には、１機種当り１組の着磁ヨークを
必要とする。しかも被着磁物に合わせて着磁ヨークも大
きくなる為、段取変更がたいへんであるという問題があ
った。The above conventional technology does not consider magnetizing objects of high quality, especially when implementing skew magnetization to reduce slot ripple, which is a factor of rotational speed pulsation in permanent magnet rotating electric machines. , one set of magnetizing yoke is required for each model. Moreover, since the magnetizing yoke also becomes larger in size to match the size of the object to be magnetized, there is a problem in that it is difficult to change the setup.
本発明の目的は多品質の被着磁物を同一の着磁装置で着
磁する際、比較的簡単な段取りでそれぞれの機種に最適
なスキュー着磁を施す着磁装置を得ることにある。An object of the present invention is to provide a magnetizing device that can perform skew magnetization optimal for each model with relatively simple steps when magnetizing objects of various quality with the same magnetizing device.
上記目的は１着磁ヨークの軸方向長を着磁しようとする
回転子又は回軸子の軸方向長さよりも薄く構成し、着磁
ヨークを被着磁物に対して相対的に軸方向に移動させる

着磁装置により達成される。The above purpose is to configure the axial length of the magnetizing yoke to be thinner than the axial length of the rotor or rotor to be magnetized, and to This is achieved by a magnetizing device that performs skew magnetization by magnetizing the object while moving it and simultaneously rotating it relative to the magnetization yoke.

一径の被着磁物は、Ｌの長いものから短いものまでひと
つの着磁ヨークで着磁可能である。As described above, since the magnetizing yoke is moved in the axial direction relative to the object to be magnetized, the axial length of one magnetizing yoke may be small. Therefore, the portions that need to be attached and detached when changing the setup are small. In addition, because the 1 magnetizing yoke is small, 1
The capacity of the power supply device that supplies current to the coil to generate magnetic flux to the magnetizing yoke is small.Furthermore, the skew angle is determined by the speed of rotation of the magnetized object relative to the magnetizing yoke, or the rotational distance. Since it can be changed by varying L, objects to be magnetized with the same diameter can be magnetized with one magnetizing yoke, from those with a long L to those with a short L.

Further, the magnetized object holding section 2 rotates at a rotational speed that matches the skew angle θ. If the skew angle of the entire length of the permanent magnet 9 is 00, then the rotation speed is such that θx' rotates in seconds.After a second, the capacitor 6 in the power supply device is discharged again to perform magnetization. While continuing the axial movement of the magnetizing yoke 1 and the rotational movement of the magnetized object 7, the capacitor 6 in the magnetizing power source 1 is repeatedly charged and discharged for t seconds to continue magnetization.
