WebAug 17, 2013 · A "mechanical" solution used in the aquarium pump world is to install a "T" right after the pump outlet with a valve and then you can simply return some of the fluid right back into the tank thus reducing the output from the main pipe. Or some pumps you can just restrict the outlet (never restrict inlet or it will cavitate) with a valve. WebThe equation for motor speed is: Where: N = motor speed in revs per minute. f = frequency of supply to the motor in Hz. p = number of poles on the stator. s = slip of motor in revs per minute. From this equation, it can be seen that the speed of an induction motor can be controlled in three ways: (a) Change the number of poles.
