Abstract: A bus bar unit is configured to supply power to coils (16) of a plurality of phases, and includes phase bus bars (47U ), (47V), and (47W) which are provided for each phase and are connected to winding start ends of the coils, and a neutral point bus bar (81) which is connected to winding finish ends of the coils, the neutral point bus bar (81) being formed by bending an elongated plate-shaped member such that a width direction of the elongated plate-shaped member and a radial direction of the bus bar unit coincide with each other, and including a plurality of bus bar pieces (82) and a connection portion (83) which connects the bus bar pieces (82) and (82) adjacent to each other, and a width of a deformation portion (85) of the connection portion (83) being narrower than a width of the bus bar piece (82).

Abstract: There is provided a rotating electrical machine capable of suppressing backlash of a magnet in the trust direction and suppressing an axial variation in the fitting position of the magnet. A magnet holder 19 used for a motor 1 has a holder base 31 fixed to a rotary shaft and a plurality of holder arms 32 projecting from the holder base 31 in the extending direction of the rotary shaft. The holder base 31 has sidewall portions 53 between adjacent holder arms 32. On each sidewall portion 53, there is formed an inner end surface 53a opposed to an axial end portion 17c of the magnet 17. Projections 55 are formed on the inner end surfaces 53a, and the projections 55 are pressed and crushed by being brought into contact with the axial end portion 17c of the magnet 17. The magnet 17 is fitted in the holder arms 32 while pressing and crushing the projections 55.

Abstract: There is provided a rotating electrical machine capable of suppressing backlash of a magnet in the radial direction and suppressing an axial variation in the fitting position of the magnet. A magnet holder 19 used for a motor 1 has a holder base 31 fixed to a rotary shaft and a plurality of holder arms 32 projecting from the holder base 31 in the extending direction of the rotary shaft. Each holder arm 32 has an arm main body 41 fixed to the outer periphery of a rotor core and extending in the extending direction of the rotary shaft, and also has a bridge portion 51 for connecting the holder base 31 and the arm main body 41 and formed to have a circumferential width W1 set smaller than width W2 of the arm main body 41. The rigidity of the base portion of each holder arm 32 is set lower than that of conventional magnet holders. Magnets inserted between adjacent holder arms 32 are held by elasticity of the holder arms 32 and this limits spread-open of holder arm end portions involved in fitting of the magnet.
