[PSUBS-MAILIST] Brushless Motor Drive

[Alan James]

Hi Psubbers
I've been thinking about motor compensation options.
Any thoughts about whether this idea may have any merits?.....
Mount a brushless motor vertically on an outboard motor lower unit gear case
& air compensate it.
The length of the vertical drive shaft from the motor to the gear case gives
plenty of margin of error for the air compensation system before any water
could make its way to the motor.
The gearing already exists for the higher speed of the brushless motor, & although
there is an energy loss through the gearing there would be some savings in 
that the motor is not directly in the path of the propellor thrust.
A can would need to be made around the motor & sealed on to the lower unit.
Regards Alan
