[JAC278] Creating Six-Phase Induction Motor Efficiency Maps
With advances in variable speed operation technology for induction motors, progress is being made in applications to fields where wide operating regions are required. With this, polyphase design may be used for the purpose of enhancing redundancy. Polyphase design includes the likes of six-phase drive using two inverters. Efficiency maps are created for both motor design and control design in order to fully comprehend the characteristics of these motors that are capable of drive within such a wide range.
In this example, a six-phase induction motor efficiency map is created in the concept design stage, and each operating point slip and iron loss are evaluated.
Efficiency Map, Slip Map
The efficiency map is displayed in Fig. 2, and the slip map is displayed in Fig. 3.
Efficiency can be understood from Fig. 2.
Slip can be understood from Fig. 3. Slip with maximum efficiency at each operating point can also be understood.
