Hello all. I am trying to increase the power of a 3 phase motor at output pin 1, 2 and 3 of connector J3. Can anyone give suggestion? I provide the schematic diagram for reference.

Thank you.

Hello there :) A word of caution!
When a polyphase
inductive motor is operated above the nameplate rating, the efficiency, current, and speed will differ from the nameplate values. Such operation may reduce the life of the motor insulation. Care must be taken to ensure that all applicable conditions, such as ambient temperature and altitude, are observed. :)
