At start the equivalent impedance of the FCMA is constant and maximum, done by the Main winding and the motor current through it.
When the motor speed increase, the cemf of the motor increase the flux in the feedback winding, as this winding is in opposition with the Main winding the total flux, so the total equivalent impedance in the module, is decreasing with the motor speed.
The design of our module, fonction of the motor data, is such as the starting current is keeping constant and the voltage at the motor terminal is continiously increasing during the motor start .
DOL, Star Delta, Soft starter, VFD
A DOL or direct on line starter works by connecting the motor terminals directly to the power supply when they are energized. A DOL starter is the simplest type of motor starter.
I think one is conventional starter motors and the other is Gear-reduction starter motor.
Across the line starter has a large inrush current.
A three point starter is a device that is meant to help start a DC motor. A three point starter will start device without much starting current.

Most of the motors are usually controlled by the soft starters which usually trip frequently. One of the steps in find why the soft starter has tripped is looking at the motor circuit protector rating.
It is an advanced power electronic device to start the motor with a very smooth starting curve. It is next generation starter compared to DOL or star Delta starter
I assume a 3 phase, AC induction motor. A star delta starter or a soft starter can be used. A soft starter is better compared to a star delta starter, but it is more expensive.
You could cheat or soft reset.
An inverter is just a device to invert one form of electrical power supplied to its input into another form of electrical power as its output. A soft starter may be included into an inverter design, its function is just to provide temporary power to the inverter until it gets started. After that the soft starter is disabled, usually by a diode feedback link.
A soft start is a starter that bring a motor from the starting point of a slow speed in to a multiple speed that can be programmed in the starter Imagine you have a big plant in your factory, the voltage will go down/up when the plant start/stop, cause the sharp start/stop The soft starter is controlling AC motor in soft start/stop to eliminate such problems.

it could go on and on. have to be lucky

You can by soft resetting a numerous amount of times.
