Summary:To improve electric motors.SOLUTION: A brushless motor comprises a rotor assembly, a stator assembly, a frame, and at least one strut. The rotor assembly comprises a shaft, an impeller, a bearing assembly, and a rotor core. The frame comprises an outer portion, and a support portion present radially inward of the outer portion, the support portion supporting at least one of the rotor assembly and the stator assembly. The at least one strut extends between the outer portion and the support portion. The strut and the stator assembly are aligned such that at least part of the strut and at least part of the stator assembly are disposed along a line substantially parallel to a rotation axis of the rotor assembly.SELECTED DRAWING: Figure 7 【課題】電気モータを改善する。【解決手段】ブラシレスモータであって、ロータアセンブリと、ステータアセンブリと、フレームと、少なくとも１つのストラットとを含み、ロータアセンブリが、シャフトと、インペラと、軸受アセンブリと、ロータコアとを含み、フレームが、外側部分と、外側部分の半径方向内側に存在してロータアセンブリ及びステータアセンブリの少なくとも一方を支持する支持部分とを含み、少なくとも１つのストラットが、外側部分と支持部分との間に延び、ストラット及びステータアセンブリが、ストラットの少なくとも一部とステータアセンブリの少なくとも一部とがロータアセンブリの回転軸と実質的に平行な線に沿って並ぶように整列されているブラシレスモータ。【選択図】図７
