、その一部が継鉄２に設けた凹部２ａ。As shown in these figures, the stator 1 has a cylindrical yoke 2. This yoke 2 includes magnetic poles 3 (permanent magnet 3a, auxiliary pole 3b) provided on the inner peripheral surface. The magnetic pole 3 is held by a cylindrical holding frame 4. In FIG. 1, 5 is a rotor, 6 is a shaft, 7 is a rotor core, 8 is a rotor coil, and 9.10 is a bracket that supports the rotor 5 and stator 1 coaxially. In this embodiment of the stator 1 configured as described above, the holding frame 4 is attached to the inner peripheral surface of the yoke 2 by inserting the magnetic pole 3 into the window 4a provided so that the magnetic pole 3 can be inserted. Recessed portion 2 partially provided in yoke 2
A and 2b were filled under pressure, and the area around the window 4a was pressurized so as to press the magnetic pole 3 against the yoke 2. By doing this, the holding frame 4 has a window 4a provided for inserting the magnetic pole 3.
The magnetic pole 3 is inserted into the center and attached to the inner circumference of the yoke 2, and a part of the recess 2a is provided in the yoke 2.
２ｂ内に加圧充填され、窓４ａの周囲部分が磁極３を継
鉄２に押圧するように加圧されるようになって、保持枠
４が磁極３を継鉄２に強固に固定保持するようになり、
磁極３を継鉄２に強固に固定することを可能とした回転
電機の固定子１を得ることができる。2b is pressurized and the surrounding area of the window 4a is pressurized to press the magnetic pole 3 against the yoke 2, and the holding frame 4 firmly fixes and holds the magnetic pole 3 on the yoke 2. It became like this,
It is possible to obtain a stator 1 for a rotating electrical machine that allows the magnetic poles 3 to be firmly fixed to the yoke 2.
すなわち非磁性金属で形成し、磁極３の入る複数の窓４
ａを設けた保持枠４を凹部２ａ、２ｂを設けた継鉄２に
収納し、収納後は保持枠４を凹部２ａ、２ｂに加圧充填
して、継鉄２に固定する。That is, a plurality of windows 4 formed of non-magnetic metal and into which the magnetic poles 3 are inserted.
The holding frame 4 provided with the recesses 2a and 2b is stored in the yoke 2 provided with the recesses 2a and 2b, and after storage, the holding frame 4 is pressurized and filled into the recesses 2a and 2b and fixed to the yoke 2.
このような状態で保持枠４の窓４ａに磁極３である永久
磁石３ａおよび補助極３ｂを挿入し、固定子１の内周か
ら雇を使用して窓４ａの周囲を加圧し、磁極３に押付け
るようにして塑性変形させ、この押圧力で磁極３を継鉄
２の内周に固定する。In this state, insert the permanent magnet 3a, which is the magnetic pole 3, and the auxiliary pole 3b into the window 4a of the holding frame 4, pressurize the area around the window 4a from the inner circumference of the stator 1 using a magnet, and apply pressure to the magnetic pole 3. The magnetic pole 3 is plastically deformed by pressing, and the magnetic pole 3 is fixed to the inner circumference of the yoke 2 by this pressing force.
このようにすることにより保持枠４は磁極３を継鉄２に
強固に固定・保持するようになって、磁極３を継鉄２に
強固に固定できるようになり、振動に強く、信頼性の高
い固定子１を得ることができる。By doing this, the holding frame 4 can firmly fix and hold the magnetic pole 3 to the yoke 2, making it possible to firmly fix the magnetic pole 3 to the yoke 2, making it resistant to vibration and highly reliable. A high stator 1 can be obtained.
なお、永久磁石３ａおよび補助極３ｂの軸方向側面１“
１，１２は軸中心０と接線をなすようにし、保持枠４の
押圧力が磁極３を継鉄２の内周に押し付けるようにしで
ある。In addition, the axial side surface 1" of the permanent magnet 3a and the auxiliary pole 3b
1 and 12 are arranged to form tangents to the axis center 0, so that the pressing force of the holding frame 4 presses the magnetic pole 3 against the inner periphery of the yoke 2.
また、保持部４は磁極３の厚さに比べて余り薄くなると
磁極３を十分に押圧することができないので、磁極３の
厚さの少なくとも１／２以上の厚さにしである。Further, if the holding part 4 is too thin compared to the thickness of the magnetic pole 3, it will not be able to press the magnetic pole 3 sufficiently, so the thickness should be at least 1/2 or more of the thickness of the magnetic pole 3.
