The 2 photos below are taken of the rating plate and the terminals of a 3 phase induction motor respectively.
- Without further information, can you identify what configuration of supply is suitable for the motor based on how the terminals have been wired up? Why do you say so?
- Draw a schematic diagram of the 3-phase induction motor connected to a 3-phase power supply. Label all the line voltages, phase voltages, line currents, and phase currents.
- Based on the rating plate values of 415V and 8.3A for delta configuration, what is the resistance per phase within the motor?
