Variable Speed Drives and Soft Starters
What are Variable Speed Drives (VSD) and Soft Starters? Variable Speed Drives (VSD) and Soft Starters are speed control devices used in AC motor systems to control starting, stopping, and acceleration of motor speed. Variable Speed Drives (VSD) allow for motor speed adjustment to match the required load, resulting in better control and energy savings and efficiency. Soft Starters gradually ramp up the motor speed to have a smooth start and reduce the initial current surge to minimize stress on the motor and extend its lifespan.
To start and stop a motor using a Variable Speed Drives (VSD), you can use a control signal to initiate or stop the drive's output.
