Replacement Pump Motor

It seems we woke up to a dead pump motor today. Noticed the overflow wasn't running and found the breaker to the pump tripped. Reset breaker, the motor did not restart and the breaker tripped again. This is a Pentair DynaPro E model MPEA6Yg-207L motor that was installed new in July 2016...so just a touch over 4 years old. For what it's worth the motor housing has had significant rust for some time now...perhaps there was water intrusion where it should not have been...don't really know though as I haven't disassembled & investigated just yet. A few questions:

- Assuming there is no electrical fault between the source and motor itself is it safe to assume the motor is 'dead' and requires replacement?

- Is it necessary that the motor be replaced with the same model? If not, what do I need to know to select an appropriate replacement of a different make/model?

- This pump was only able to drive my Zodiac vacuum at the appropriate speed/with enough suction to get it to climb the walls with the motor on high speed and all intakes other than the vacuum closed off. Can I purchase a higher HP replacement motor that would then create enough flow to drive the vacuum 'at speed' without having to close off all return lines other than the vacuum port? If so, how do I know what is needed to accomplish this?

Thanks in advance for any guidance on this!

You have a 2hp 2 speed pump and motor... I think you could upgrade to the new V-green VS motor, please contact Inyo and make sure and also ask if your motor is a square or round flange...

You should be able to use the 2.7 V green motor but you will need to upgrade your impeller to the 2.5 hp impeller for your pump, Inyo should be able to help you there also :)

Thanks for the input Cowboycasey.

I checked out the links in your post which raised another question for me. My current set up has a separate timer mechanism as well as what I'll just describe as a pressure switch that changes speed on the motor as well as turns on/off the blower for the spa. It's just rubber boot attached to an airline that runs to the remote timer. How would that work with a motor like these that are a) variable speed (vs. 2 speed) and b) when the motor has a built in timer like these is it necessary to bypass the remote timer? If so then how would I turn the spa blower on/off?

So this motor and all VS motor require constant power all the time... You would connect it to the side of the timer suppling power to the timer... the timer would still run everything else that you have connected to is... this pump is very interesting and dos things in an ingenious way... I just did this with my SWG and it works perfect...

Say you want you to turn your spa blower on...

1. buy this 120v ac to 24v dc adapter Amazon.com: NOYITO AC to DC Precision Buck Power Supply Module AC 110V 100V-264V to 24V 1A 1000mA Isolated Step-Down DC Module (24V 1A): Home Audio & Theater
2. connect the 120v side to your spa motor
3. connect the 24v dc side to the new V green pump on the digital inputs 1 2 or 3 (page 11 here) http://images.inyopools.com/cloud/documents/v-green165-usermanual.pdf

when you turn on the blower the VS motor will change to the speed you select :)
