Hi. I want to build a debarker for my sawmill and am looking for an economical motor option.

A debarker is like a circular saw with a 1/4" wide blade that runs just in front of the bandsaw blade and removes dirty bark, so the bandsaw blade stays sharp 2-3 times as long.

The factory debarker has a 12VDC 1550RPM 3/4 HP motor and has to be able to handle the weather during operation.

I am trying to find a cheaper alternative to the factory option. Would a 1750RPM motor with everything else equal be effected much in torque? I have found some of these on ebay.

What type of motor am I looking for? I thought of a small .5KW car starter motor, but there must be something in the design that limits it's duty cycle as I can see it burning up. Example:



Here is the model motor for the factory debarker:


Thank you for your help. -Mike

 

You could try the automotive starter as long as it is PM field, the wound field series starter motor operates in a run-away condition without load, so may not be suitable, but they do have very high torque.

Thank you Max. I will read up on "PM field" starters when I get home this afternoon.

 

Hi! Wanted to thank you for the help. I built the debarker and will be installing it this afternoon. I ended up finding a new old stock motor for it at a very good price. Here is a pic:
