We have .ht motor which is 60Hz.we run on 50Hz.so that it's speed reduce
but we had one prob.that motor winding temp increase up to 135 deg.we
want reduce this temp.what to do?we arrange ext.cooling fan but not much
effect.we want reduce this temp. Inhouse without affecting much.cost. also
don't want reWINDING OF MOTOR?

You may have to reduce the load more till you get the
desired temp rise

As you have reduced the speed ,the cooling effect of the
shaft mounted cooling fan is also reduced .Either you have
to reduce the load by about 10% or replace cooling fan .
