Disc set for rotor or stator of e.g. synchronous motor for electrical or hybrid propulsion system of vehicle, has spacing portion provided between protruding lugs so that permanent magnets are fixed into receiving spaces by lugs

摘要

#CMT# #/CMT# The disc set (1) has receiving spaces (5) that are formed to receive permanent magnets (7). These receiving spaces are formed by receiving space recesses which are formed in the individual lamellae (3). The protruding lugs are formed in the receiving space recesses so that the permanent magnets are oppressed in the receiving space. The spacing portion is provided between protruding lugs so that the permanent magnets are fixed into the receiving spaces by protruding lugs. #CMT# : #/CMT# An independent claim is included for electric machine. #CMT#USE : #/CMT# Disc set for rotor or stator of electrical machine (all claimed) such as generator and synchronous motor for electrical or hybrid propulsion system of vehicle. #CMT#ADVANTAGE : #/CMT# The spacing portion is provided between protruding lugs so that the permanent magnets are fixed into the receiving spaces by protruding lugs, so that the permanent magnets can be reliably and securely accommodated into the receiving spaces with less tolerance. The cost required for fixing permanent magnets into the receiving spaces can be reduced. The single cutting tool is used for the manufacture of the lamellae, so that the disc set can be manufactured at reduced cost. The disc set is simple in structure. The permanent magnets are coated with nickel layer, so that the risk of damage of permanent magnet can be reduced during the assembly of the permanent magnets and the corrosion properties of the permanent magnet can be improved. Thus the operational safety of the permanent magnet can be improved. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of the disc set for rotor of electrical machine. 1 : Disc set 3 : Lamellae 5 : Receiving space 7 : Permanent magnets 9 : Rotor.
