摘要：
This paper presents the method for improving the performance and efficiency of a three-phase asynchronous machine with squirrel cage architecture used in HVAC applications and refrigeration. Recently, these machines have been driven by V/F controlled VFDs, which led to decreasing the overall cost of the HVAC system and increasing its overall efficiency simultaneously. Load torque in the blower and pumps is proportional to the rotor speed. This can be improved further by optimizing the flux's magnitude. This work presents the optimization of flux using the field weakening method to increase the machine's overall efficiency.
