Web6 jul. 2015 · A VFD drive that is properly sized to a motor is capable of delivering 150% torque at any speed up to the speed that corresponds to the incoming line voltage. Fig. 2—Typical speed/torque curve for a NEMA-B induction motor (courtesy of Houston Armature Works Inc.). WebThe variable frequency drive (VFD) varies the frequency and hence varies the speed or torque of the induction motor as per the requirements of the load. As VFD provides the power efficient operation, smooth speed and torque control but also leads the harmonics in the system. Harmonics are generated due to use of power electronic switching devices.

Web2 mrt. 2024 · Figure 2: An induction motor (an asynchronous motor) requires slip to produce torque. Motor speed is the difference between the command frequency and the slip frequency.
