I need a quick bit of advice (I've searched the thread, and cant really find my answer)
I am trying to size a DC motor. The speed is not important, it will be be seriously low speed like 1RPD (revolution per day ) to achieve this I am seriously gearing the motor down with a sprocket drive. The load it balanced and the center of rotation is co-indecent with the center of gravity.
Correct me if I'm wrong, but once the motor is running at a constant speed, it will only have to over come the friction of the system - as it is balanced - therefore the main concern of sizing the motor is the starting torque, as the mass moment of inertia is very large (large sprocket).
T=J X angular acceleration
My question is this: Knowing the mass moment of inertia of my system how do i size a DC motor with the least power requirements.
Oh, and one more thing,I predict the motor is likely to stop start many many time.
