Hi, I am new here.

I have some problems with the engine motor. What is the difference between starting torque (or locked up torque) and stall torque?

What happen if motor torque = load torque? Will the mass move up with constant speed or stay stanionary? motor torque = stall torque = load torque?

Thanks for any help and suggestion! :smile:

Regards
coolrox

Assuming you are asking about an electric motor...

Starting torque = torque reqd to overcome friction, load inertia, stiction, etc., and accelerate the load inertia. This is meant to be a transient value.

Running torque or load torque = less than starting torque, keeps the previously accelerated inertia + load at steady state speed.

Stall torque = torque value that will slow down and stop your motor + load. Hopefully you have properly wired your motor protection devices and they will kick in. Otherwise the motor will draw a lot of current, heat up, catch fire, burn your building down.
