Replacement motor for Sta-Rite Max-E-Pro

My Sta-Rite Max-E-Pro 1.5 HP model P6EA6F-206L motor recently stopped working.  It powers a PEC2000 inground pool cleaner.  It had started making a very loud noise like the bearings were going out but I waited too long to replace them and now it just hums and will not turn at all.  When I removed the motor, I noticed what looks like a brass plated assembly that was fastened to the end of the back of the motor shaft had come appart.  There are two springs on either side of this assembly and one of them had broken off and the part of the assembly that was held on by the springs had fallen off. Sorry for referring to this as an assembly but I have no idea what it is and cannot find a parts breakdown for the motor itself.

My Questions:

* Could the broken assembly be the reason the motor stopped working?

* Is it possible to replace this broken assembly?

* What would be my options for an energy efficient replacement for this motor?

Thanks in advance.

Hello Mem9900 - The part in your picture is called the governor. It controls the opening and closing of the start switch. This part is replaceable. The governor for your particular motor is part number 5270-92. However, your motor probably has other issues (start capacitor, bearings, start switch).

My recommendation would be to replace the motor. The energy efficient single speed option is part number UQC1152. The UQC1152 would be approximately 10% more efficient than what you currently have. The most energy efficient option would be a variable speed motor. The variable speed motor for your 1.5HP Max-E-Pro pump would be model ECM16SQU

We recommend replacing the seals when you replace the motor. The seal kit is part number GOKIT79.

 Thanks a lot InyoRob.  I will replace the motor rather than the governor.  I currently have 2 veriable speed Sta-Rite motors driving the filter and one driving a waterfall.  Those motors appear to have a serial control line in addition to AC power.  Does the ECM16SQU require a control line as well?  The current wiring for the motor I am replacing only has AC power for the controller to the motor.  I believe my controller can do two additional veriable speed motors but I'd have to check on how to add one if it is required.  Since this is driving a in ground cleaner I only need one speed but it would be nice to be able to adjust that speed for maximum efficency.

I read the user's manual for the V-Green 165 and it appears there is a serial control line.  I need to coordinate the new motor with the current filter motor since the filter motor needs to run while the clearner motor is running.  If I understand correctly, connecting just the power lines to the motor will start a 24 hour scheduler rather than just starting the motor when my controller applies power.  I guess if I set the schedule to be on all the time at the speed I decide is optimum it will start right away and just restart every time the power is applied.  Is this correct?  Alternatively I can check serial control compatibility with the current controller I have which is a PentAir (I'll have to get the exact model number when I get home).

Is it possible to get conformation that the PentAir Intellitouch pool system controller is compatible with the ECM16SQU veriable speed pump?

The Pentair Intellitouch can tell the Century VGreen ECM16SQU to turn on and off. However, the speed settings can only be set and controlled on the ECM16SQU interface.

Hi InyoRob,

Thanks for your help.  I ordered and received the new motor and the tune up kit.  The new motor was working great however I noticed it was leaking.  I took it appart agin and it looks like I unfortunately made a mistake when putting it back together.  I am pretty sure I put the seal in backwards (hard white plastic piece facing the motor instead of away from the motor) and ended up breaking the impeller.  I'll have to order a new tune up kit and the impeller.  Can you tell me which impeller is the correct replacement for the Sta-Rite Max-E-Pro 1.5 HP model P6EA6F-206L?  Live and learn...

Sorry to hear about your problems. The correct impeller for the Sta-Rite Max-E-Pro P6EA6F-206L is part number C105-238PB.
