How Brushless Motors Are Classified

Three classifications cover most of what you will see in a specification sheet.

By phase angle

Brushless motors divide into 60° and 120° phase angle types.

By speed

They divide into high-speed and low-speed brushless motors. A boat drive sits firmly at the low-speed end — the Caroute range tops out at 1,800 rpm at the propeller.

By position sensing

They divide into sensored and sensorless brushless motors, according to whether a motor position sensor is fitted.

What It Means for Your Boat

When you compare two drives on paper, check which of these three you are actually comparing. A 60° sensored low-speed motor and a 120° sensorless high-speed motor are not the same machine with different numbers.

FAQ

Questions About This Topic

What are the three classifications?
By phase angle (60° or 120°), by speed (high or low), and by whether a position sensor is fitted.
Where does a boat drive sit?
At the low-speed end — the Caroute range tops out at 1,800 rpm at the propeller.
Does Caroute publish the phase angle?
No. It is TBC on the published material; ask if it matters for your integration.
Is the Caroute motor sensored or sensorless?
Not published. Ask Jane Cao if your controller requires a specific arrangement.
