 Load torque characteristics

 Torque / speed characteristic

Power / speed characteristic

1.Torque almost constant; power proportional to speed.

2.Torque increases proportionally with the speed; power proportional to the square of the speed.

3.Torque increases proportionally with the square of the speed; power proportional to the cube of the speed.

4.Torque decreases in inverse proportion to the speed; power constant.
