Abstract

The International Electrotechnical Commission totally enclosed, fan cooled 100 Motor frame for 2.2 kilowatts squirrel cage induction motor have been manufactured with both 24-slot stator and 36-slot stator. This study compared the two solutions along the lines of rated performance, material consumption, and robustness of design. Since the difference between the two motors is basically the number of slots in the stator, similar machine data were adopted for them. The unknown data were calculated from standard machine equations carefully suited for the motors. The data so obtained were used as input to the RMxprt model where the motors were simulated. The results show marginal difference in all the parameters considered such as efficiency (0.09% in favour of the 36-slot Stator), power factor (0.0014 in favour of the 24-slot Stator), annual cost of operation (N687.88 saved by the36-slot stator), and overload capacity. The inference of this study is that the two stator designs are adequate solutions for the 3hp motor having International Electrotechnical Commission totally enclosed, fan cooled 100 Motor frame, and that while the 24-slot stator design would be easier and cheaper to manufacture, the 36-slot stator design is however more robust and cheaper to operate.
