Application of Energy-Saving for an inverter feeds three-phase induction motor

Yanbu Journal of Engineering and Science, 2021
Three-phase induction motors are the most prevalent AC motors used in many applications. Operation of these motors at load power less than that of the motor full-load power leads to significant power losses and reduces the motor's efficiency. To mitigate

Protection of AC motors by means of microcontrollers

2000 10th Mediterranean Electrotechnical Conference. Information Technology and Electrotechnology for the Mediterranean Countries. Proceedings. MeleCon 2000 (Cat. No.00CH37099), 2005
In this study, a system was designed and implemented to make protection for the current, voltage, winding temperature of induction motors. In the system, the voltage transformer with transformation ratio of 400/5 V and current transformer with transformation ratio of 25/5 A were connected to each phase of induction motors.
