#CMT# #/CMT# The machine has a stator (16) with a stator core (17) provided with stator slots, where stator has a stator winding (18) arranged section wise in the stator slots. A part of the stator winding arranged in the stator slots is connected with an end winding (45) by a coil section, where the stator winding is interrupted in a circumferential direction by gaps (63, 69). Rings (78, 81) are arranged radially within the gaps and fastened to a rotor (20), where the gaps exhibit an axial length. The rings cover is made of a non-magnetic material. #CMT#USE : #/CMT# Electrical machine i.e. claw pole generator, for a motor vehicle. #CMT#ADVANTAGE : #/CMT# The ring extends over a region where pressure fluctuations develop radially in relation to the gaps so that surface pressures on the rotor are stable over the circumference in the region of the ring, thus reducing formation of aero-acoustic sound waves, and hence providing an electrical machine with improved noise behavior and cooled construction units. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of an electrical machine. 16 : Stator 17 : Stator core 18 : Stator winding 20 : Rotor 45 : End winding 63, 69 : Gaps 78, 81 : Rings. |
