The curve in Figure 4 shows the actual speed-torque curves which result when a motor is operated from a constant volts-per-Hertz voltage source supply. When low voltage and low frequency is applied to the motor, the maximum torque available decreases at reduced speeds. This is a result of the resistive voltage drop of the stator windings.

The graph below illustrates—in a very general sense—the way speed affects torque in impact drivers and impact wrenches. The speed vs torque "curve" in cordless impact drivers and impact wrenches works differently. Given full power to the motor, an impact tool produces more speed to the rotating anvil.

Figure 5 shows torque-speed curves for a DC drive with armature voltage regula-tion. For either a DC drive or an AC drive, the drive's torque-speed curves are an infinite number of parallel lines that are nearly vertical.
