What would cause a brushed motor to lose strength?
My wife used her mixer to make two pounds of dough for years, but recently the motor would struggle and eventually stop. The only way to use the mixer now is to make smaller batches of dough.
I took a look under the hood, and all seems OK. The brushes on the motor are clean and making good contact, the cooling fan moves air over the motor as it should, all the gears were well lubricated and moved freely, nothing was broken.
What made the motor lose it's mojo? Is there a way for me to make it strong again?
