Ball mills on the other hand, as far as process requirements are concerned, did not require variable speed. However, frequency converter based drive systems provide benefits that improve the ball mill operation. FIXED SPEED CONFIGURATIONS The key issue to operate a mill in a fix speed mode is the starting.

The cycloconverter is a frequency changer which converts a polyphase voltage with the frequency f1 into a single or poly-phase voltage with a different, lower frequency f2. In the case of the gearless mill drives the operational output frequency is from 0.3 Hz up to about 5
A Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. Other names for a VFD are variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive, microdrive, and inverter.. Frequency (or hertz) is directly related to the motor’s speed (RPMs).

Motor starters – also called soft starters or soft starting devices – are not frequency converters, but devices that simply reduce the voltage. You use them if your motors are connected to line supplies that are either very weak, or to which other loads are connected that are very sensitive to voltage fluctuations.

Advantages of VSDs vs Soft Starters. VSDs provide all the Soft Starter benefits and more. Compared to Soft Starters, Variable Speed Drives (VSDs) offer much more flexibility in terms of features and settings and, depending on the application, much bigger cost savings, especially where speed control is required.

Now that we have talked about some applications and how the soft starter is wired into a system, let’s dive into the internal workings of the soft starter. The main component of a soft starter is a Triac which is designed to limit the applied voltage to the motor. Triac consists of two back to back Thyristors or SCRs.

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.
