I would like to build a handheld rotating brush to clean the hull of my boat.
Something like this: http://www.maxdepaz.es/clonar/wp-conten ... 902220.jpg
On a much smaller scale.
I could drive it with a belt from above the water. But having a geared hubmotor in the brush would be awesome.
I have a large lathe and can machine my own parts.
So first question:
How is the stator connected to the shaft on a bafang geared hubmotor?
Has anyone every replaced the shaft of a motor?
My idea is to machine a new stainless shaft longer then original with a large smooth area outside the hub. Bolt new machined aluminium housings to the outside the side of the hub and house double lipseals in these parts that seal on the shaft. The same way a regular outboard motor gearcase shaft seal is made.
Most dificult part might be getting the wires trough the new shaft.
And maybe fill the motor with outboard gearcase oil? With a inspection plug to check for water.
So in case of water leakage the oil start turning too milk and nothing is damaged yet als long as the oil is replaced on time.
All ideas welcome.
