Nominal sped of submersible motor

3" motor                                              N = 2800 rpm

4" motor                                              N =2900 rpm

6" motor                                              N=2900 rpm

8" & 10" motor                                  N=2900 rpm

 

Note:

1)      Weights are approximate.

2)      Copper weight is @ 600gm per HP (+/-) 10%.

3)      Copper weight varies acceding to RPM , selected for 1440 RPM in case of induction motor

4)      Gross weight of motor  increases with decrease of RPM
