motors for SQ stacks

[PeterL]

Question for the repair braintrust:

In the laundromat that i'm working for, we have a number of Speed-Queen stack driers that have 1/2 HP drive motors that seem to be prone to centrifugal switch failures. The motors are Marathon Electric motors with a 56Z frame. Has anyone else used GE or Baldor motors or some other brand that are more reliable ?. I am assuming there are other motors out there with the same dimensions and that have the wiring provisions to power the ignition circuit as these motors do.

The stack driers are 6 or 7 years old, and i seem to spend a lot nice evening time rolling around on the floor skinning my hands on the insides of these machines. At the same time we have some 30 plus year old SQ singles that seem to have their original motors.

Any thoughts appreciated.

welcome to the board. I am sure someone who has worked on SQ stack motors will be responding. I only have 3 of them, and when a motor goes the dryers might go also :)
I did have a mat with a number of old Cissel dryers at one time. As the motors died, the price from Cissel was near $400 ea. I asked a local electric motor repair shop if they could sell me something like it, and they did,, for about $170 ea. Yes, ouch, compared to SQ for $75, but a big savings for me. BTW, those Cissels may have been older than me at the time, so I don't fault the brand. So check your local guys, maybe even Grainger. You are way ahead of me with the "56Z frame" stuff.......

The motors themselves are good quality. The problem is with lint. The only solution would be a completely sealed motor. That would probably be a problem because of the heat. In this business, lint is something you have to live with.

I've found that an air compressor and air gun about every 2months does wonders. Blow thru the air holes in the motors until nothing else comes out. You'll be amazed what comes out if you've never done this!

I agree with ferd however I don't keep such a rigerous schedule as he does. I use compressed air and a shop vac to clean out my dryer motors usually once per year, I should do it more often.

The origional fan motor on the STO300 has been replaced by an updated part #. HOWEVER....It is still the wrong type of motor for the intended application. The newer version motors have a "better" centrifigual switch. ?????? This motor should be a closed design, and it is not. There are two reasons the switch goes bad. Lint gets into the switch and lint collects on the fan and vibrates the switch to death. They need regular maintanence. While you are cleaning the fan, clean the thermister and limit stat.
