ZJSHUYI ZJSHUYI Difference between soft starter and frequency converter....

First of all, the purpose of the soft starter and the frequency converter is different. The main problem solved by the soft starter is to reduce the starting current of the large load and reduce the impact on the power grid. The startup of large equipment will generate a very large startup current, which will cause a large voltage drop. If the traditional star-delta and other step-down methods are used, it will not only cause a larger current impact to the power grid, but also cause a larger load to the load. Mechanical shock, in this case, a soft starter is often used to start, to achieve no shock throughout the start, so that the motor starts more smoothly, thereby reducing the capacity of the power supply. The frequency converter is mainly used in places with speed regulation. It can control the speed of the three-phase motor, such as the speed regulation of the spindle motor of CNC machine tools, the transmission control of mechanical conveyor belts, large fans, and heavy-duty machinery. #Inverters can be used in applications, etc. In general, its functional practicability is far greater than that of soft starters. Secondly, the control function of the inverter of the soft starter is different. The main function of the soft starter is to adjust the starting voltage of the motor to realize the smooth start of the motor and reduce the impact of the motor on the machinery and power grid. However, since it controls the voltage by chopping the conduction angle, the output is an incomplete sine wave, which leads to low starting torque, high noise and high harmonics, which will pollute the power grid. Although the soft starter also has various functions such as the setting of the current limiting function and the setting of the starting time, the function parameters of the soft starter are relatively monotonous compared with the hundreds of function command parameters of the inverter. Generally speaking, the function of soft starter is not as much as that of frequency converter. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #softstarter #motorsoftstar #softstarters #softstartechnology  #VFD  #INVERTER #frequencyinverter   #frequencyconverter  #converter  #inverters   #vfds  #softstartermarket #softstarterprice #vfdmarket
