Modeling and simulation of double-stator cage induction motor

Abstract

The poor start-up characteristics of driving induction motors result in large losses during normal operation. Compared with ordinary induction motors, double stator cage induction motors have lower starting current, larger starting torque, and higher efficiency and power factor during normal operation. The motor changes the starting current and starting torque by changing the voltage difference between the two stators, thereby improving the starting performance of the motor. This article first analyzes the basic structure and working principle of the double stator cage induction motor, divides the entire starting process into three stages: initial, switching, and running, establishes its mathematical model, writes a simulation program with MATLAB, and obtains the simulation results. The poor start-up performance is compared and analyzed. The research results show that the double stator cage induction motor is a new structure motor with excellent starting characteristics, which will be widely used in related fields such as industry and promote the development of production.
