Paper Summary:
This study defines the load torque demand, which is the torque required to drive the load at a given speed.
The load torque demand is proportional to the square of the speed. This is typical for gear systems.
The information provided defines the motor torque capability as a function of speed.
The steady-state running speed and torque of the motor driving the load are the intersection of the motor torque capacity curve and the load torque demand curve.
If the actual operating speed is higher or lower than the normal operating point when the induction motor is initially energized, the excess motor torque capability is applied to accelerate the gear system and load inertia to the normal operating speed.
