Torque characteristics fan and pump loads are: resistance of air or liquid within a certain speed range generated roughly proportional to the square of the speed. As the speed increases, the load torque increases by the square of the rotational speed. In the curve of the output frequency and output voltage type 1: U / f smaller low speed, the electromagnetic torque generated by the motor is smaller as the speed increased, U / f corresponding increase generated by the motor electromagnetic torque is also increased, and the entire curve presented as a function of U = f (f) is approximately the square of the relationship, and the load torque characteristics coincide. Type 2 is suitable for proportional torque load. Type 3 is suitable for constant torque load such as belt conveyors, hoists, etc. Constant torque load characteristics is that the entire frequency range, torque load essentially unchanged. Type curve in the output frequency and output voltage of 3: U / f is linear, is a constant value. Thus the electromagnetic torque generated by the motor is also kept constant, and the load torque characteristics coincide.
