- Top angular speed of electric motor 2 answers
I connect a DC motor to a flywheel with a given moment of inertia. I then supply that motor with a constant voltage and current for an infinite time interval. What do I need to know about my motor to predict the top angular speed of my flywheel? How do I calculate the top angular speed of the flywheel?
I read here that an unloaded motor will reach a terminal angular velocity when the back EMF rises to the same value as the applied voltage. This concept makes sense to me, but where in a motor's specifications can I find the constants in the equation for back EMF? $$E_b = \omega \phi k_b$$ Moreover, can that calculation be used to find the terminal angular velocity of a loaded motor?
