How does soft start work? A soft starter is any device which controls the acceleration of an electric motor by means of controlling the applied voltage. An Induction motor has the ability to self start owing to the interaction between the rotating magnetic field flux and the rotor winding flux, causing a high rotor current as torque is increased.
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 STO soft starter is designed to smoothly start (and stop) three phase AC induction motors by utilising a constant current system (closed loop). As well as efficient soft start and soft stop, the STO range adds essential motor protection with excess start time, phase loss and motor overload functions.
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
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

SR22 semi-conductor soft starters provide many advantages when used instead of electro-mechanical contactors to control 3-phase AC induction motors. The SR22 soft starters use thyristors for controlled reduced voltage motor starting and stopping, then switch to internal contacts for effi-cient running at rated speed. Features

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.
M350 starters are designed to meet the starting torque requirements of the application and the starting duty (starting time and starts per hour) specified by the user. The ratings given to M350 starters are therefore variable and application dependant. 5 starter model nominal motor kW rating at …

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.
