Rotating electrical machine having a structure for support of a bus bar and terminal block

A rotating electrical machine, comprising:

• a rotor provided on a peripheral surface of a rotary driving shaft;
• a stator oppositely spaced apart from an outer peripheral surface of the rotor and held inside a circular-cylindrical frame;
• a connection plate having a bus bar connected to one end of a coil wound around the stator and an insulating holder, the bus bar including a plurality of bus bars laminated in a radial direction and the insulating holder holding a plurality of the bus bars;
• a terminal block having a connection terminal to which is welded the bus bar extracted from the connection plate to electrically connect an outside wire that supplies the coil with power and the bus bar;
• a case storing the frame and the terminal block;
• and
• an annular connection plate cover made of an insulating material and covering the connection plate,
• the rotating electrical machine being characterized in that:
• a part of the outside wire is fixed to the case and the terminal block is directly or indirectly fixed to the frame, and
• the terminal block together with the connection plate and the connection plate cover is fixed to the frame by an annular pressing member press-fit inside the frame.
