All of the motors I've seen from Winco have been
shaft, bearing, and or general clean up issues and not
anything in the windings (then again the same can be
said for the DC motors I do.
The BT models I've been getting from Winco Foods are
made by Danaher (Czech Republic) and in fact are good
motors from what I can tell so far, minus the abuse my
customers dish out 8^)
The data tag on the Drive unit says that it's a 3~87
Hz, 34 volt 174 amp, 7.5 KW at 2500 RPM's.
One of the biggest issues that I see is that these
Danaher motor use an encoder bearing on one end that
runs 600.00 bucks if it needs replacing 8^o IMO
that's a pretty costly bearing and in fact costs more
than most of my total invoices for full DC motor
repairs. Although the winding aspects are not the
problem with these units the fact that I'm already
seeing them do to these other issues tells me that
there is nothing that someone can design that another
person can't beat the crap out of 8^o
I'll grab some pics before I get these two I have in
shop back out, and I'll post them at the site when I
get a minute.
BTW, there's nothing like an old fashioned DC brushed
motor that any general controller can make run 8^)
Pinpoint customers who are looking for what you sell.
