WebMay 7, 2024 · The torque-speed curve is a constant, dependent only on the difference between synchronous and actual rotor speed. This is fine, but eventually, the notion of “volts per Hz” runs out because at some number of Hz, there are no more volts to be had. This is generally taken to be the “base” speed for the drive.

WebMathematically, the speed curve is the derivative of the curve that plots the distance traveled vs time (or for 1D properties their value curve). So, the distance traveled is the integral of the speed curve. If you learned differential calculus in school, you might remember that the integral of a function corresponds to the area under the curve. WebIndian Railways WebThe 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. himountain cruise
