If we know the stall torque and no load speed of a pm dc motor, the maximum power motor can deliver is P max = 1/2* Tstall * 1/2* ω(no load).
A mechanical device that produces stall torque has an output rotational speed of zero. Electric motors are capable of developing torque when stalled.
However, as the current flowing is at its maximum while an electric motor is halted, they are vulnerable to overheating and potential damage.
The no load speed is the speed when running at nominal voltage and zero load.
So, the maximum power motor can deliver is P max = 1/2* Tstall * 1/2* ω(no load).
