Investigation into soft-start techniques for driving servos

WebbThe first consideration in choosing a motor control technology is the speed control requirements. Some soft starters have limited slow-speed control between starting and stopping. Slow speeds can vary from 1 to 15 percent of the full speed and can be used in a maintenance or alignment operation. WebbA soft starter is incapable of speed-control. It only restricts starting current by applying the voltage in a ramp. The consequence is that for much of the ramp, the torque is severely …
