Keywords: Electric motor, submersible pump, estimation of speed in rpm, mechanic performance of electric motor (ProQuest: ... denotes formulae omitted.) Extendend Summary Electric motors are the most commonly used power source for operation of pumps. The algorithm outputs have been obtained for the two-poles (3000 1 / min) threephase asynchronous electric motors with a voltage range of 380-400 V in the IE1 efficiency class and the load ratio between 50-100%. Developed algorithm were given these regression equations; for 6 inch pump diameters at 3,7-37 kW power ranges operating speed is estimated with n = 866,101 - 155,225·PL + 0,750·nN, for 7 inch pump diameters at 22-55 kW power ranges operating speed is estimated with ni = 834,375 - 112,500·PL + 0,750·nN, for 8 inch pump diameters at 18,5-105 kW power ranges operating speed is estimated with n = 853,273 - 137,697·PL + 0,750·nN, for 9 inch pump diameters at 115-168 kW power ranges operating speed is estimated with n = 829,687 - 106,250·PL + 0,750·nN, for 10 inch pump diameters at 81-185 kW power ranges operating speed is estimated with n = 824,464 - 99,286·PL + 0,750·nN. Beside of findings of this research, for the 6 -10 inch pump diameters with the developed regression equations, the operating speed can be estimated with between ± 1,414 and ±6,707 min-1 standard error by using the rated speed and load ratio from the nameplate values of the motors in the 3.7-185 kW power range.
