As a result, the terminal fitting (7) becomes long when viewed from above, and accordingly, the terminal block (6) and the bracket (5) to which the terminal block (6) is attached are also extended in the longitudinal direction of the terminal fitting (7). It has to be set long in the motor axial direction, and since the terminal block (6) is installed on the outside of the circumferential side of the bracket (5), it also protrudes greatly in the motor radial direction. There was a problem that it became large.
このため、特に狭いスペースに設置されることの多い小
形モータでは使用範囲が限定されていた。For this reason, the range of use has been limited, especially for small motors that are often installed in narrow spaces.
