Abstract: A rotor of a brushless motor includes permanent magnets formed on the outer circumference of a rotating shaft to have a fan shape in an axial cross section, magnetized from the inner radial surface toward the outer radial surface, and arranged at even intervals so that magnetic poles of the outer radial surfaces are disposed alternately with respect to the polarities thereof in the circumferential direction. The outer radial surface of each of the permanent magnets includes a center of curvature on a line segment connecting a center point in the circumferential width on the outer radial surface with the axial center of the rotating shaft, and formed as a cylindrical surface having a radius of curvature smaller than the distance of the line segment. Each of the permanent magnets is magnetized in a parallel orientation so that the orientation of magnetized magnetic flux is parallel to the line segment.

Abstract: A fastener system that when assembled prevents the assembly from accidently falling out of the housing. The fastener system includes a reduced shank bolt, a bushing with internal threads and a snap ring relief, a snap ring, and a housing modified to receive the bushing and the snap ring. The flange may have a flange relief to seat the snap ring when the fully engaged.

Abstract: A mounting bracket for a motor, including a hoop structure and a plurality of mounting feet. The hoop structure includes a wall surface. The wall surface of the hoop structure includes the mounting feet formed by punching the wall surface of the hoop structure so that a plurality of grooves close to the mounting feet is produced on the wall surface of the hoop structure, and one end of each mounting foot is coupled to the wall surface of the hoop structure. The mounting bracket for a motor of the invention has a simple structure, low cost, and reliable connection and requires less material compared to conventional mounting brackets. The mounting bracket is suitable for different types of motors.

Abstract: A motor casing, including a hollow motor casing body. The wall of the motor casing body comprises a plurality of brackets and a plurality of grooves which are formed simultaneously by punching the wall of the motor casing body. The plurality of grooves is disposed one close to one of the brackets. One end of each bracket is coupled to the wall of the motor casing body. The motor casing has a simple structure, low cost, and reliable connection and requires less materials compared to conventional motor casings.

Abstract: A generator including a generator frame (2, FIG. 1), frame rings (4) extending from an inside surface of the frame (2), stacked laminations forming a stator core (88) disposed within the generator frame (2), a spring bar (40, FIG. 2) spanning a distance between at least two frame rings (4), a first spring bar end attached to a first frame ring (4) and a second opposing spring bar end attached to a second frame ring (4), at least one bracket (80) attached to the spring bar (40); and a first and a second keybar (84) attached to the bracket (80), each keybar (84) for engaging a corresponding groove within the stator core (88).
