The inverter can adjust voltage and frequency to realize the speed control and starting of the motor, while the soft starter only changes the voltage to protect the motor. It has a complex structure and high price. The inverter generates harmonic current during operation, while the soft starter only generates harmonics during the starting process and no longer generates them after starting.
Speed control ability
The inverter can adjust voltage and frequency to realize the speed control and starting of the motor, while the soft starter only changes the voltage to protect the motor. It has a complex structure and high price.
Operating characteristics
The frequency converter will generate harmonic current during operation, while the soft starter only generates harmonics during the starting process and no longer generates them after starting.
