    What has RPM to do with current? Torque will increase as speed decreases. At the same line voltage if the current changes, will the power rating remain the same?

    If the pump is designed for 1440 RPM and consumes 15 KW, connecting a 15 KW 2900 RPM motor to it will severely overload the motor and cause a burn out.

    If the pump is designed for 2900 rpm with 7.5 kw motor and we want to run the pump in 1440 rpm with 7.5 kw motor what will be the result
