Fortress Resistors proudly offers the GINO-AKA range of Liquid Resistance Starters (LRS)—robust, high-performance solutions designed to meet the demanding start-up requirements of large wound-rotor motors. Engineered for industries like mining, cement, and manufacturing, these starters deliver smooth torque control, reliable motor protection, and seamless integration into heavy-duty operations. With scalable configurations and advanced monitoring options, the GINO-AKA series sets the standard for precision and durability in industrial motor starting.
Liquid starters are used to start wound rotor induction motors (WRIMs) by introducing a variable resistance in the rotor circuit of the motor. With the AK type starter series, Fortress Resistors provides a cost-effective, reliable solution for the cement and industrial sector. For the minerals market, particularly for Ball and SAG Mills, Fortress Resistors offers the MAK type starters with additional features for the specific demands.
Fortress resistors offers a special liquid resistance starter for shredder applications to guarantee the highest performance for the demanding environment on shredder installations: The SKS series. The SKS starters have a specially developed drivetrain and measuring facilities:
The ARL system is predominantly used for motor powers up to 500kW. The robust design guarantees high operational reliability and long service life. In addition, the simplicity guarantees best value per kW and fits even the tightest budget.
Advantages of the compact starter ARL at a glance:
Complementary to our liquid starter line Fortress Resistors also provides a stepped starter with oil immersed resistors. The design combines the advantages of a resistor starter with those of a more economical heat carrier (oil) and a high protection class for applications in harsh environments. Robust power contactors guarantee high operational reliability and a long service life combined with low maintenance requirements.
With the AKAMAS monitoring device Fortress resistors provides a specially developed tool that measures the rotor currents in two phases of the wound rotor induction motors (WRIM) rotor circuit and calculates multiple starting performance characteristics of a resistive starter and WRIM in real-time. The measured data of the AKAMAS is logged in customized software and can be analyzed by the users. In addition, the starting curves and performance indicators are displayed on the integrated touch display.
The AKAMAS is the first standalone device that enables the users to have a solid measurement-based analysis of the starting procedure and empowers them to adjust the liquid resistance starters settings to meet the requirements of the application.
