Re: DC Motor For Lawnmower

A lawn mower would be the perfect application for a brushless motor. They are more efficient that regular brushed DC motors, but they need special speed controllers. Here are two brushless motors which would probably work just fine, most likely with just a single reduction off the motor shaft via timing or V-belts.

Re: DC Motor For Lawnmower

Thank you everyone who answered, particularly artdutra for those links. I'll keep looking around a bit and hopefully find something within my price range.

Sounds like there are quality issues with the 3KW motor. Lots bearing and magnet failures. Perfect size though.
