Induction motor

An induction motor (10), comprising:

• a motor casing (20) comprising an irregular octagonal shape with a central open area and configured to house a cooling system within an outer wall (140) and an inner wall (130) of the motor casing (20), wherein the cooling system comprises a plurality of interconnected cooling channels (180) and a plurality of air ducts (170), wherein the motor casing (20) comprises a set of four side walls (160) and a set of four corner walls (150);
• a stator assembly (60) housed within the central open area of the motor casing (20), wherein the stator assembly (60) comprises:
• a hollow cylindrical stator stack (260) fabricated with a plurality of rectangular shaped open slots (280) on inner surface periphery and a plurality of cleating notches (290) on outer surface periphery;
• and
• a set of intertwined stator rods (250) configured as stator windings and housed within the plurality of rectangular shaped open slots (260);
• a rotor assembly (70) configured to be fitted inside the stator assembly (60);
• wherein the rotor assembly comprises:
• a hollow cylindrical rotor stack (350) fabricated with a plurality of predesigned rotor slots (380) on outer surface periphery, a plurality of vent holes (390) and a rectangular notch (400) of predefined dimension on inner surface periphery;
• and
• a set of rotor bars (360) configured as rotor windings and housed within the plurality of predesigned rotor slots (380);
• a shaft (80) configured to be fitted to the rotor assembly (70), wherein the shaft (80) comprises
• a rectangular depression (450) for proper alignment with the notch (400) on inner surface periphery of the rotor assembly (70);
• and one or more equispaced steps (440) on both axial ends for aligning mounted induction motor components;
• and
• a fan positioned on the first axial end of the induction motor (10) and configured to assist inflow of air into the plurality of air ducts (170).
