Use Case: High-Torque Motor Ramp-Up

Liquid starters are used to prevent damaging inrush currents and mechanical strain during start-up of large motors. Typical installations include mills, crushers, pumps, and long conveyor drives found in mining, infrastructure, and industrial plants.

Standard Liquid Starter System

Gino-AKA Liquid Resistance Starters supplied by Fortress offer smooth, controlled motor acceleration through a submerged electrode system. By varying resistance in an electrolyte medium, the LRS manages torque ramp-up while protecting motor windings and reducing maintenance costs.

Liquid Starter Models

The Compact model is suitable for motors up to 1,200kW. For higher-powered or dynamic load applications, the MAK and SKS series offer faster adjustment, better response, and high thermal stability. Fortress can advise the best model based on motor size, start frequency, and duty cycle.

Use Case: High-Torque Motor Ramp-Up

Oil cooled starters are used for controlling start-up torque in large motors that drive high-inertia equipment such as crushers, mills, and conveyor systems. They prevent excessive inrush currents and mechanical wear, making them ideal for mining and industrial plants.

Oil Cooled Starter System

The Gino-ESE 3PA3 is a stepped-resistance starter where resistance changes are handled through contactor switching. These steps are submerged in insulating oil, allowing for stable thermal management and a compact footprint. Unlike stepless liquid systems, the 3PA3 operates through discrete switching points for cost-effective control in harsh environments.

System Design

Fortress supplies the Gino-ESE OCS in custom configurations, including mild or stainless steel tanks, auxiliary equipment, and local control integration. Designed for easy maintenance and built to perform in demanding Australian conditions.

Use Case: Optimised WRIM Start-Up Monitoring

The AKAMAS 2.0 system is purpose-built for wound rotor induction motors (WRIMs), offering real-time insight into starting performance. It’s typically deployed alongside liquid or oil-cooled starters to measure torque behaviour, rotor current, and acceleration patterns—enabling better system tuning and preventive diagnostics.

Monitoring Functions

AKAMAS measures rotor current across two phases during startup, calculates real-time performance metrics, and displays all data on an integrated touchscreen. Logged data can be exported or accessed remotely via Ethernet, Wi-Fi, or USB connection for deeper review.

Optimisation and Maintenance

With AKAMAS, users can fine-tune starter parameters, detect degradation in motor start behaviour, and pre-empt equipment faults. It’s especially useful for high-power motor systems where startup consistency is essential for operational safety and efficiency.
