Regarding soft start
Thread Content
Should a 60HZ motor be started using a soft starter or an inverter? Why, solve it.
What’s the point of using it? It’s sufficient to just start it with a soft start function. If you want to control the speed, then use an inverter; an inverter can provide a soft start function as well, but it’s much more expensive!
The power grids in our country are all 50HZ; so this must be an imported motor. It is only possible to supply the motor with a 60HZ power supply using frequency conversion, but this has never been done.
It must be the inverter. Soft starting refers to methods used to reduce the starting current and increase torque, and an inverter can definitely achieve this. Since you are using 60HZ, it’s impossible to do this without an inverter
I agree with what was said about the sofa – it depends on your actual needs as to how you want to control this motor!
Agree to variable frequency; soft start cannot change the 50Hz power frequency of China’s power grid
We all use 50HZ; it’s not possible to reach 60HZ without frequency conversion
The domestic voltage is 50HZ; if you want to use 60HZ equipment, it can only be done through an inverter. With an inverter, there is no need to use a soft starter anymore
A soft starter cannot change the frequency; it is only the inverter that can increase the motor’s speed by raising the frequency. The motor’s nameplate will definitely indicate values such as 380V 50hz 2980r/min and 60hz 5520r/min. As mentioned by Shanghai You, a soft starter can only reduce the starting current of the motor, thereby minimizing the impact on the power grid caused by the high current generated during motor startup
A 60HZ motor? Variable frequency drives are used for frequency control, while soft starters are used for voltage control
