For AC motor, you can change motor RPM by changing its supply voltage or by changing supply frequency. For DC motor, you can change motor speed by controlling armatyre voltage or field current.

No. The water pump is designed for a specific RPM. It will not operate correctly, and will probably be damaged, if you attempt to operate it at twice the design RPM.


What is the maximum RPM does a 3 phase motor run at?

The formula for RPM is ; RPM = Hz x (120 (constant)) divided by the # of poles. Number of poles a motor has; # of poles = Hz x (120 (constant)) / RPM.

How do I determine RPM of a 3v DC motor?

RPM stands for revolutions per minute. This is calculated for different devices and can indicate how fast something is going. For a DC motor, the RPM is calculated by how many times the motor turns.
