Rotor Slot Distance Effects on Output Parameters in Single Phase Induction Motors
In this paper, single phase induction motor which has different rotor slot distances are analyzed with 2-D Finite Element Method (FEM). The analyses are carried out using ANSYS/Maxwell program which solves equations with FEM. The model has same stator and rotor slot geometry. The variable parameter is slot distance which is between outer diameter of rotor core and top border of slot. The single phase induction motor model has 2 poles, 96 W shaft power and run capacitor. It is connected to 220 V, 50 Hz AC network under the full load. Slot distance is varied from 0.2 to 1 mm in 0.1 mm steps. Magnetic model is solved for each distance. Electrical performance characteristics which are speed, efficiency, current, torque and power factor (PF) are determined. Magnetical flux density (B), flux lines and current density on bars are demostrated visually. Motor performance is improved as the slot distance decrease.
