Abstract
A rotor () for an electric machine, in particular a permanently excited synchronous machine. At least one recess () is formed on the outer wall () of the receiving space () and forms a non-magnetizable space () adjacent to the lengthwise surface () of the permanent magnet (). Due to this non-magnetizable space (), iron losses in the stator teeth can be reduced in particular during operation of the electric machine in the field weakening range, which may result in a rise in efficacy of up to 3% for the electric machine.
