Abstract: The alternator is used in the motor vehicles and provides increased current output. It comprises ring (17) and (17a) connecting the second claw poles (16) and (16a), and its peripheral surface which is opposite to the second claw poles (16) and (16a) is profiled and protruded outwards, shaped by the adjacent surfaces of inner and outer truncated cones whose axes coincide with the axis of the shaft. On the peripheries of external side plates (23) and (23a) at diameters equal to the inner diameters of the carried pole configurations and axes coinciding with the axis of the shaft (1) stationary are fixed second magnetoconductive rings (26) and (26a) whose surfaces located on the side of the first magnetoconductive rings (17), (17a) are shaped like a groove whose shape corresponds to the shape of the profiled protruded outwards peripheral surface of the first magnetoconductive rings (17), (17a) comprising them with possibility for their free rotation in the corresponding groove.

Abstract: It is designed for traction motors in motor-in-wheels, fans, and direct driving electric machines. The inner stator (1) consists of pole elements (13) comprising external periphery (14), core (15), part of yoke (16), externally wound bobbin (3). The pole elements (13) on inner aluminum housing (4) are stationary fit. In housing (4) on bearings in end bells outer rotor (8) carrying motor-in-wheel (6) or another operating mechanism is sustained. The inner housing (4) is a carrier of the electrical machine and the operating mechanism, laterally closing side plate-carrier of electronic control device.

Abstract: It is designed for operation as alternator and motor-alternator for mobile vehicles, as servomotor, as electric motor for electric cars and others. It has reduced overall dimensions in two mutually perpendicular directions while maintaining power. A part of the outer surface of the stator /5/ is smooth and is covered by aluminum body /8/ consisting of mirror located and pressed one to another fore-part /8a/ and rear part /8b/ of aluminum body /8/ with a section with square oval shape. In the corner zones of the aluminum body /8/ are formed axial ventilating ducts /9/. In case of need the rotor space is isolated from outside air by non-metallic cylindrical partition /23/.
