Title:
MODULAR SYSTEM AND METHOD FOR PRODUCING AN ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2015/043799
Kind Code:
A3
Abstract:
The invention relates to an modular system for forming at least one first electric machine and at least one second electric machine of different outputs. The electric machines are formed as an inner rotor with an external stator (1) and an internal rotor (2) which has permanent magnets (4). The modular system is characterized by stators (1) which are identical at least with respect to the stator internal diameters for the electric machines, whereas the rotor (2) of the first electric machine has ferrite magnets and the rotor (2) of the second electric machine has rare earth magnets.
