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! 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.

i have a 7.5 hp electric dc motor
what is the torque produced at 1000rpm
