Softstarter, 0066471, DOLD

The 0066471is an electronic device designed to enable 1-phase or 3-phase induction motors to start smoothly.This device slowly ramps up the current on two phases, therefore allowing the motor torque to build up slowly.This reduces the mechanical stress on the machine and prevents damage to conveyed material. These features allow cost saving constructions of mechanical gear. When the motor is up to full speed the power semiconductors is bridged to prevent internal power losses and heat build up. In addition this product allows a softstop function prolonging the stop time of the motor, preventing high counter torques from abruptly stopping the motor.
