FAQ

Frequently Asked Questions

Are these articles about Caroute motors specifically?
They explain the permanent magnet brushless DC motor in general. Where a figure applies to a Caroute drive it is named as such — for example the 50% efficiency advantage and the five times service life quoted against the N platform.
Where do the figures come from?
All of them are published on the Caroute technical resource pages.
Which article should I read first?
“Why a Brushless DC Motor Is More Efficient Than a Brushed One” covers the ground the other four build on.
Can I get a copy of the catalogue?
Yes — the Caroute Brushless Boat eMotor catalogue PDF is on the downloads page.
