Abstract: Single-phase induction machines are found in various appliances such as refrigerators, washing machines, driers, air conditioners and fans. This paper presents a mathematical model and simulation results of dynamic characteristics of the split phase induction motor for different values of the inductor and moment of inertia at no-load conditions. Based on the state vector analysis of the system, the dq axis model of the split phase induction motor is deduced. It reveals the periodicity and chaos for various system parameters. Accordingly, a chaotic-speed fan is derived varying the motors internal parameters or the operations
