Rotor device of integrated stater-generator motor and rotor working system

A rotor system, the system comprising:

• an engine, a crankshaft connected to the engine, a rotor device connected to and rotates together with the crankshaft, a rotor iron core fixed on the rotor device, a clutch connected to the rotor device, and a gear box connected to the clutch;
• wherein;
• the rotor device is a monobloc cast machined to become an inseparable, one-piece structure;
• the rotor device having a central portion and a brim projecting radially therefrom, wherein the rotor device has an external side surface of a top of the central portion being a first surface, an external side surface of the brim being a second surface, an inner side surface of the brim being a third surface, and a fourth surface which connects the first surface with the second surface;
• the first surface of the rotor device is formed with multiple through holes for fixing with a crankshaft;
• the third surface of the rotor device is formed with multiple threaded holes for connection with a clutch, and the threaded holes pass through the second surface corresponding to the third surface;
• wherein the second surface is provided with multiple bosses, each boss being associated with a corresponding threaded hole;
• multiple triangular ribs are provided between the second surface and the fourth surface;
• and
• an extruded extrusion platform is provided on the first surface, and all the through holes are formed on the extruded extrusion platform, the shape of the extruded extrusion platform is a ring.

A rotor device of an integrated starter-generator (ISG) motor, comprising:

• an inseparable, one-piece structure casted as a monobloc cast and then machined, the structure including:
• an external first side surface lying in a first plane;
• a brim portion defined by:
• an external second side surface lying in a second plane spaced from and generally parallel to the first plane;
• and
• an inner side surface lying in a third plane spaced from and generally parallel to the second plane;
• a generally arcuate surface extending between the first side surface and the second side surface;
• wherein:
• the first side surface of the structure is formed with multiple through holes for fixing with a crankshaft:
• the second side surface of the structure is formed with multiple threaded holes for connection with a clutch, the threaded holes passing through to the inner side surface;
• wherein the second surface is provided with multiple bosses, each boss being associated with a corresponding threaded hole;
• multiple triangular ribs provided between the second side surface and the arcuate surface;
• and
• an extruded platform is provided on the first side surface, and all the through holes are formed on the extruded platform, the shape the extruded platform is a ring.
