Cart barely moves in foward and reverse

Rcpipercub

Hi to all I am new here and a new batterie powerered cart owner. From what I can tell I have a 2001 medalist series cart. When I bought it one of the posts came off of the motor. The place I got it from had another motor laying in the shop. I put it on and now it barely moves. The solenoid is clicking and I am getting low voltage to the motor. The old motor was stuck and I damaged it removing it. before I could get all the information off of the old motor the shop threw it away because of the damage. I had the motor gone thru and tested and it is supposed to be good I think it is the wrong motor. Would a Sepex work in a series cart? I will not be able to look into anything for the next couple of days. Due to work. The shop is not a golf cart place the guys there do not know much about them. I am sure if I surf the threads I could find something on this so if there is another thread with this topic if you could get me a link I would appreciate it. Thanks in advance

Sir Nuke

first thing, lets verify whether you have a SERIES or a SEPEX drive system

Thanks sir nuke. I am sure the cart is a series thru my research I will have to remove the motor to look at the windings for motor verification. Do you know right off if the motor is wrong would it run? It may be a sepex. It does not have any sensing wires on the back. Thanks for the quick response.

You may be correct - a sepex motor will barely turn in a series system.

Just curious if this may be a fast/easy confirmation. Do SepEx motors have different sized studs for rotor than stator, or are they all the same, like a series?

Thanks Scotty b I think I need a motor I will pull it and identify it. Thank you for the fast response. I will keep you all posted on my findings.

All four studs on the motor in EZGO's first sepex drive attempt, the DCS, were the same size and were labeled A1, A2, S1 & S2, so the only way to distinguish them from a series motor was the part numbers, or looking at the field/stator windings. Sepex has a lot of thin wire while series has a few turns of thick wire or ribbon.

-------------
PDS and later sepex motors have smaller studs for the field winding that are labeled F1 and F2. And they usually have a speed sensor on the rear of the end cap.

Mistakenly putting a DCS motor in a series drive cart is a definite possibility.

Yeah, I assumed field (stator S) windings would be obvious, but since he had it installed...

Part number is the only way I know of to differentiate between a series and a DCS motor when installed.

I stole your picture for my stash.
Is that your AMD 7126 Raptor?


The picture of the series motor I posted was from a Marathon with side mounted motor.

yurtle

Yes.
