The difference with Soft Starter vs Variable Frequency Drive (VFD) is the method of starting employed. A soft starter reduces voltage, not Hertz, and as such the starting torque at 23 Hz is next to nothing. The soft starter is essentially robbing the motor of voltage at all points between 0 and 59 Hz, peak (Line) voltage met at 60 Hz.
A motor soft starter is a device used with AC electrical motors to temporarily reduce the load and torque in the power train and electric current surge of the motor during startup. This reduces the mechanical stress on the motor and shaft, as well as the electrodynamic stresses on the attached power cables and electrical distribution network, extending the lifespan of the system.
Hard start of mill motor, throwing ball charge Most mills are designed with a soft starter arrangement; a typical mill starter system could include a Liquid Resistor Soft Starter (LRS) or Variable Frequency Drive (VFD), or it could be a clutch. Regardless of the system used, it is important to use correct start .
This is invaluable with, for example, ball mills, allowing starting with a full load rather than the alternative of having to start the mill with an empty barrel then progressively load it to full capacity. A fully loaded "hard start" for such equipment would essentially be applying full power to a stalled motor.
the voltage, current and power factor during the start to calculate the full load figures. During the running stage, the power factor continues to be monitored. When the power factor drops, the motor is lightly loaded, and there are losses inherent in the design of a motor causing excess energy to be wasted. These are known

The mill used for this comparison is a diameter by meter long ball mill with a 5000 HP drive motor. It is designed for approximately 90 per hour. This type twocompartment mill is a state
III. The advantages of improved ball mill. The VFD start is the soft start, which has avoided the startup impulse current in the working frequency. Meanwhile, it will protect the equipment. It can operate as the set multistage PLC which is set automatically.

SR33 soft starters are semiconductor devices designed for reducedvoltage start/stop control of 3phase AC induction motors; typically in applications that would otherwise require an electromechanical wyedelta starter. SR33 soft starters are suitable for use in industrial environments. EN 55011/22 Class A. SR3322 through SR3355
be appropriate. Stellar soft starters should not be used if the starting time will exceed 30 seconds. The Stellar Advantage Fully Digital with Touchscreen, 3Phase Soft Starters S Series, 17A – 477A S soft starters are fully digital, and use thyristors in all three motor phases for controlled reduced voltage motor starting and stopping.

CD Automation Soft Starters are perfect for a multitude of applications. The following list illustrates our current applications but please feel free to contact us if you have a requirement not listed here.
Oct 05, 2015· The disadvantage of the soft starter technology compared to the frequency converter is that it is unable to control the speed and is unsuitable for applications requiring speed control. When starting loads with high inertial torque, for example in ball mills, it is easily applicable and has to be selected at a higher power level.
Using Soft Starter for starting heavy electrical loads In my practice I have used soft starters to start the water pumps and fans with power up to 200 kW at 400 V. It is excellent solution slow start, soft stop and less starting current.
