Abstract: The application relates to a stator frame of an electrical machine having a first end and a second opposite end. A flange is protruding from the first end and surrounding the first end. The stator frame includes cooling fluid channels and cooling fins on the outer surface of the stator frame extending from the first end to the second end. The stator frame is formed as a single piece. The ends of the outer walls of the cooling fluid channels in the first end are connected to the flange and the cooling fins extend to the junction of the flange and the first end.

Abstract: An electric motor which includes a stator with an outer perimeter provided with beams and a stator frame surrounding the stator and including at least two intermediate plates having openings for receiving the stator. For enabling simplified assembly of the electric motor, the intermediate plates include first contact surfaces forming a tight contact with corresponding second contact surfaces provided on the beams. The electric motor is provided with bolts extending through the intermediate plates between the outside of the stator frame and the openings at an exactly predetermined position of each of the first contact surfaces and engaging threaded holes provided to an exactly predetermined position of each of the second contact surfaces.

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.
