In the design steps of the induction machines, reducing the power consumption level of the induction machine is a very important issue. Winding topology is one of the most important design parameters for induction machines. Variation of the number of turns in the slots has a significant effect on the performance of the machine. In this study, unlike the studies in the literature, only the number of turns are changed and analyses are performed. Parameters such as stator outer diameter, inner diameter, package length, number of slots, air gap length, coil section and etc. are kept constant. 6 different induction machines which have 6 different winding topologies are designed. 3 of the machines are designed half-coiled and the other 3 machine are designed whole-coiled. Both winding topologies have different turn numbers for a single slot. The turn numbers are 96, 106 and 116 respectively. Noload, locked rotor, and load tests are conducted on these machines. According to the test results and analytical results, performances of the machines are considered. In this way, increasing the turn number for both winding topologies has a decreasing effect on the iron losses of the motor. Similarly, increasing of the stator and rotor resistances directly affects the copper losses of the machine negatively. When considering the efficiencies of the machines, maximum efficiency is achieved for half-coiled 116 turns numbered topology. Similarly, maximum efficiency is achieved for whole-coiled 106 turns numbered topology.
