Brushes not available for electric motor...
I have a question and a rant!
I've got a leaf blower that needs new brushes. Neither Toro (the manufacturer) nor Mamco (the motor supplier) will sell the brushes to me or refer me to a third party. I got an email response from Mamco stating that they couldn't give me the specs for the brushes because it was considered proprietary info.
I thought the response was silly given that I could make the mechanical, chemical, and electrical measurements myself with the right equipment.
In addition, I thought about the car industry. Every part on every vehicle is probably proprietary to some car company or supplier. I can hear it now..."Oops, I'm sorry your headlight is bad so you'll have to buy as new car".
This company obviously wants to sell a new motor that costs more than the whole blower all because a $3 replaceable part failed. Any suggestions would be appreciated!
Thanks in advance,
Dick
A way to make your own brushes
I don't know if this will work for you, but it is worth a try.
Back in the 1940s I watched my dad make replacement brushes for a motor. He cut open a standard dry cell battery (say C size). In the middle is a black cylinder. It is mostly graphite, the same material as most motor brushes. With a saw and file, shape the material to fit your brush holders. For less sparking and more power, shape the face concave that rides on the commutator for good contact.
