Approach: A new stator slot shape is proposed based on the results obtained from the iterations with Rotational Machine Expert (RMxprt) software and the performance is compared with that of the existing stator slot shape, for a 3-phase, 5 hp, 380 V, 2-pole motor The motor with both the Designing Squirrel Cage Rotor Slots with High Conductivity… conductivity of cast copper in rotors of induction motors. Deep bar and multiple cage effects are useful in design of such machines. It is shown that a useful understanding of how different slot shapes work may be developed through the use of frequency response curves that describe rotor slot impedance as a function of rotor frequency.
