Motor speed torque characteristics
NettetInduction Motor Speed Torque Characteristics. When applying VARIABLE Frequency Drives(VFD), the speed-torque characteristics of an induction motor started at full voltage and operated on utility power should first be reviewed. Figure 1 shows the speed-torque curve for a 30HP, 1800 RPM induction motor in an Nettet11. feb. 2024 · The characteristics of a DC motor are represented by a torque-speed curve that slopes downward to the right, with torque as the horizontal axis and speed as the vertical axis. The speed is highest when there is no load, falling away to the right until maximum torque is reached at zero speed.
