Product description

The BA 9018 softstarters are electronic devices designed to enable 1-phase or 3-phase induction motors to start smoothly. It 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. When the motor is up to full speed the semiconductors are bridged to prevent internal power losses and heat build up. In addition BA 9018 allows a softstop function prolonging the stop time of the motor, preventing high counter torques from abruptly stopping the motor.
