Abstract: The disclosure provides a motor and a method for assembling the motor. The motor includes: a bus bar including a first portion of the bus bar and a second portion of the bus bar, the first portion of the bus bar and the second portion of the bus bar are defined separately; a first support component having a first support surface supporting the first abutting portion of the first portion of the bus bar toward the first direction; and a second support component having a second support surface supporting the second abutting portion of the second portion of the bus bar toward the first direction. The first portion of the bus bar further includes a first connecting portion, and the second portion of the bus bar further includes a second connecting portion. A distance between the first connecting portion and the second connecting portion is variable in the first direction.

Abstract: The disclosure provides a hollow shaft and a method for manufacturing the same. The hollow shaft includes: an outer periphery component having a cylindrical shape, and the outer edge of the outer periphery component has a polygonal shape; an inner periphery component having a cylindrical shape and is fitted to the inner wall of the outer periphery component; and a bottom component including a bottom plate and a cylindrical body, the extending direction of the bottom plate is perpendicular to the axial direction, the cylindrical body extends from the radially outer circumference of the bottom plate along the axial direction toward the outer periphery component, and the inner wall of the cylindrical body fits the outer wall of the inner periphery component. The outer periphery component, the inner periphery component, and the bottom component are separately defined components. The hollow shaft of the disclosure includes three separate components defined separately.

Abstract: A motor is provided, including: a rotor that is arranged in a rotatable manner centered on a central axis and has a shaft and a rotor core arranged around the shaft; a stator arranged so as to face the rotor in a radial direction; and a detector located on an upper side of the rotor core in an axial direction. An upper surface of the rotor core in the axial direction has a first concave portion recessed downward in the axial direction, and a portion of the detector is inserted into the first concave portion. An electrical product including the motor is also provided.
