Soft Starters place a device called a reduced voltage starter, or soft starter, between the motor and the incoming utility line to regulate the amount of current fed to the motor. Soft Starters enable the AC induction motor to speed up in smaller, resulting in less current drawn than with a traditional motor starter.

Siemens Standard Drives Application Handbook

1.1 What is a Variable Speed Drive? A Variable Speed Drive (VSD) consists of a Motor and some form of controller. Early electric VSDs consisted of AC and DC motors combinations which were used as rotating controllers. The first electronic controllers used Thyristor (SCR) Rectifiers which controlled the voltage, and therefore the speed of DC motors.

The VSDs provide a ‘soft start’ which, together with running the mill machinery at lower speed, reduces excessive wear and extends the operating life of the machines. The farm’s miller can use a mobile phone or iPad, connected remotely to the VSDs, to control the grinder and crusher motors to enable them to talk through the demonstrations at different speeds.

How will VSDs alter motor efficiency? - Control Design

Dec 14, 2017 The soft start Ideally, you would start by installing soft starts on most large motors. A soft start is a VFD hybrid with a bypass across-the-line contactor that ramps up motors to the across-the-line speed and then closes the across-the-line contactor to take the ramping module off-line.

Choosing Between Soft Starters and Drives

In applications such as fans, pumps, compressors, mixers, and conveyors—reduced voltage soft starters (RVSS) or variable frequency drives (VFD) can be used instead of traditional contactors or motor starters to reduce inrush current. Both RVSSs and VFDs reduce the AC RMS voltage applied to the motor during startup.
