Claims (4)
回転軸に嵌合した回転子鉄心と、前記回転子鉄心の外周面に固着された永久磁石とを有する回転子とを備え、
前記電機子巻線は、回転軸方向に延びる直線部と、軸方向に直交する方向に曲げられるコイルエンド部とを有し、
前記回転子は、前記筒状の固定子の内部に空隙を介して対向するように配置されているスロットレスモータにおいて、
前記電機子巻線のコイルエンドの、前記永久磁石と対向していない部分に、電機子巻線内周面を覆わないように電機子巻線と同一内径寸法で、補助鉄心を設け、
かつ、前記永久磁石の軸方向の端部側に、前記永久磁石と軸方向に間隔をあけて、永久磁石と同外径の磁性リングを配置し、
前記補助鉄心と前記磁性リングを、径方向の空隙を介して対向させたことを特徴とするスロットレスモータ。 A stator having a cylindrical stator core, and an armature winding fixed to the inner peripheral surface of the stator core;
A rotor having a rotor core fitted to a rotating shaft, and a permanent magnet fixed to the outer peripheral surface of the rotor core;
The armature winding has a linear portion extending in the rotation axis direction and a coil end portion bent in a direction orthogonal to the axial direction,
In the slotless motor, the rotor is disposed so as to face the inside of the cylindrical stator via a gap,
In the portion of the coil end of the armature winding that does not face the permanent magnet, an auxiliary iron core is provided with the same inner diameter as the armature winding so as not to cover the inner peripheral surface of the armature winding,
And, on the end side in the axial direction of the permanent magnet, a magnetic ring having the same outer diameter as that of the permanent magnet is disposed with an interval in the axial direction from the permanent magnet,
A slotless motor, wherein the auxiliary iron core and the magnetic ring are opposed to each other through a radial gap.
The slotless motor according to any one of claims 1 to 3, wherein an interval between the magnetic ring and the permanent magnet in an axial direction is wider than a distance from a surface of the permanent magnet to a stator core.
