摘要：The three-phase induction motor squirrel cage has a characteristic change in the event of a change in temperature beyond the motor operation, which leads to changes in the stator so that the resistance value affects the performance of the rotational speed of the motor, the motor rotation speed changes are influenced by the amount flux generated by the flow of resistance in stator. This paper aims to monitoring the motor rotation speed a characteristic three phase squirrel cage induction againts shift in the stator resistance value using a PI controller and a sensor of the motor speed in which the reference modeling is used motor stator current and stator flux. All of the three phase system is transformed in quadrature and direct axis.The resistance change of approach to equality of the number of turns in each phase in the stator. The Direct Torque Control method is used because the process of the motor speed is determined by the stator flux, torque, and position the sector to determine the input of inverter switching obtained from the Lookup Table [6]. The value of resistance in flux estimation gives the value of the flux hysteresis band against the actual performance.
