Abstract: A two-pole TEFC (totally enclosed, fan-cooled) electric motor is concerned. A housing of the motor as an inner space, into which a stator assembly, a motor shaft and a rotor assembly fixed to and surrounding the motor shaft is fitted. A mounting foot structure radially protrudes from the outer surface of the housing for mounting the induction motor to a planar base structure. The mounting foot structure includes four mounting points defining corner points of a rectangular mounting footprint of the motor, such that the rectangular mounting foot print has two opposite sides parallel with the motor shaft. Furthermore, the mounting foot structure including at least an additional mounting point positioned on each side of the mounting footprint parallel with the motor shaft, between the corner points of the mounting footprint.
