Motor temps???

[Courtlandjs]

What temperatures should my D&D torque motor not exceed? 48v club car D&D motor, Alltrax xct 500, 30" tires....drove for and hour or so non stop yesterday and motor was hot, but I could hold my hand on it for around 5 seconds???? Is it getting to hot?

[Revolution]

thats pretty normal.

To really know whats too hot look at the motor name plate for the wire temperature rating it will be a letter like "H".

[Courtlandjs]

Yea it has h rating.....so it's fine as long as it does exceed 356 degrees f?

[TerryH]

Well, yes and no. That is what the insulation is rated for but it's going to end badly if the motor gets that hot. 200 or so on the case is the max.

The case temp will normally be cooler than the rotor and stator windings, so like Terry is saying keep it well below the wire temp rating on the case.

After a 10 mile drive at 20-23 mph, my D&D motors were 133* in the front and 140* on the rear motor. 77 outside air temp.

At 100 in August they get quite a bit warmer.

After playing with my new temp gun, I don't think I exceeded 120 degrees, havent checked motor but I think it's fine

Took the cart out today with a 4 people on it. Drove it wide open for an hour stop and go.... motor casing was at 175 and vented cap 115 degrees..... sound ok?

I talked with Vic at D&D about this same thing 2 weeks ago after reading a thread on here about adding a temp sensor to a series motor. He said as long as you keep the case temperature surface below 110C (230F),{preferably not above 100C (212F)if you can help it} you will be fine.

From what I've read the highest temperatures are reached AFTER the cart has been sitting after measuring the temp. So I would push it past 100-110C if I plan on driving back to where I need to be, unless you don't mind waiting a while for it to cool back down.

Thanks for the info, I should be alright then
