Tips: What will the output torque be when the motor’s rotating speed changes?

Starting torque and maximum torque under the driving of VFD are smaller than those directly driven by power supply.
When the motor is powered by a power frequency supply, the starting and acceleration impact are huge. When the motor is powered by a VFD, the impact would be much weaker. Power frequency starting would produce a huge starting current. When a VFD is used, the output voltage and frequency of VFD are gradually added to the motor, so the starting current impact would be much smaller.
