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 2-3 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.
The Benshaw variable frequency drive powers the 4160Volt - 3500HP synchronous ball mill motor during positioning to smoothly rotate the ball mill and bring it to the proper position for maintenance. The customer's previous system utilized multiple DC contactors and a motorized cam switch to position the mill.

Maximise your crusher or mill throughput by installing a soft starter at the motor input. The soft starter allows the motor to operate at its upper thermal limit, while care-fully monitoring thermal capacity to ensure motor protection. The crusher can then safely ride through tempo-rary product overload situations The soft starter
SR33 soft starters are semi-conductor devices designed for reduced-voltage start/stop control of 3-phase AC induction motors; typically in applications that would otherwise require an electromechanical wye-delta starter. SR33 soft starters are suitable for use in industrial environments. EN 55011/22 Class A. SR33-22 through SR33-55
III. The advantages of improved ball mill. The VFD start is the soft start, which has avoided the start-up impulse current in the working frequency. Meanwhile, it will protect the equipment. It can operate as the set multi-stage PLC which is set automatically.

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.
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 …
Feb 12, 2009· The motor does not want to make it over the cascade point in soft start mode. When this happens, we bypass the soft start, and the mill starts right up. Inrush current across the line is in the neighborhood of 1300 amps. We don't like to do this often, because it leads to increased failure of the stator windings. I would say that the motor stalls.

The Stellar Advantage Fully Digital with Touchscreen, 3-Phase Soft Starters SR55 Series, 17A – 477A SR55 soft starters are fully digital, and use thyristors in all three motor phases for controlled reduced voltage motor starting and stopping.
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

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 start-up. 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.
