Side thrust of OMA-5025-375 electric motor shaft.
Hi Guys,
I have been experimenting with various types of rotocraft for several years.
These are the cyclogyro rotorcraft with horizontal axis rotor shaft.
I want to use the most powerful electric motor available which I presume is the OMA-5025-375 rated at 1550 watts.
I use toothed timing sprockets and belts to reduce the rpm down from 10,000 to 700rpm.
Assuming side loading on the motor shaft is not possible, I have the initial sprocket mounted between two bearings and then propose a 6mm shaft extending our one end and coupled to the 6mm motor shaft.
I guess a similar problem comes up with using these motors in larger RC helicopters?
Is there an off the shelf coupling that can be attached to what is intended to be a propellor mounting boss on the motor?
Jack.
