Abstract: The purpose is to accommodate large axial channels in a slim electric machine without sacrificing its torque density and radial dimensions. This is possible with a rotor (11) provided with permanent magnets (12) and a stator (13) with slots (15) for coils (20A-c), where the slots (15) are separated by teeth (16, 17), which electrical machine include teeth (17) not carrying coils (20A-c), which teeth (17) are provided with axial channels (18, 18') protruding into the teeth (17) and neighboring back iron so that an area of the channel (18, 18') inside the tooth (17) is comparable to or even larger than the an area of the channel (18, 18') in the back iron. The channels serve for transportation of fluids and other substances through the machine and also to integrate a motor protector, which may be required in down-hole applications. There are also novel manufacturing techniques associated with the new concept.
