What is the difference between a VSD and a Soft Start

We are frequently asked, what the difference is between a variable speed drive and a soft starter? The difference is the speed that the motor can run when at full speed. With a soft start starter, the motor is reduced when voltage is started; and then when the motor is at full speed, or a Continue reading

Soft starter VS variable speed drive AC Motor VFD Drives

A soft starter is a basic device which will ramp up the speed of your motor to full speed over a preset time, easing mechanical stress and also easing the high inrush currents which can be experienced by starting a motor under load. A breaker will cut the supply to your motor if the load is too high. A variable speed drive will allow you to control a motor (to varying degrees of accuracy

How does soft start work? Soft Starter Motor Soft

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. As a result the stator draws high current and by the time the motor

The difference between VFD and Soft Starter

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.
