  1. MEDIUM VOLTAGE VFD MOTOR CONTROLLER Liquid Cooled Components Active Front End - No Transformer 3300 – 6900 VAC 700 – 2500 HP www.system-controls.net Contact: sales@system-controls.net

  2. Single 1000 HP, 4160 VAC Motor Controller with Rubber Tire Option

  3. 4160 Volt VFD Underground Motor Controller • Skid-Mounted Continuous Weld Design • Input and Output Couplers Standard • Rubber Tire Option

  4. 4160 Volt VFD Underground Motor Controller • Voltages from 3300 to 6900 AC • Horsepowers from 750 to 2500 • Regenerative Applications Standard • Constant Torque Duty – 150% Overload Standard • Custom Design Allows for 250% Overload

  5. PowerFlex 7000 Kit Rockwell Automation PowerFlex 7000 Liquid-Cooled Direct-to-Drive kit packaged for Underground Use Liquid Cooled Rectifier and Inverter

  6. PowerFlex 7000 • Active Front End (AFE) is Regenerative - Standard • AFE means no Integral Transformer Required • Direct-to-Drive (D2D) means 4160 vac In and 4160 vac Out to Motor • Liquid Cooled Components Stay Cooler and Cleaner = Longer Life • Reduces Harmonics on Electrical System

  7. Liquid Cooling for Longer Life! • Closed-Loop De-Ionized Liquid Cooling • Integral Flat Plate Heat Exchanger Keeps Closed-Loop System Clean and Contained

  8. Liquid Cooling for Longer Life! • Flange Fittings for Mine Cooling Water Input and Hot Water Return • Redundant Pumps for Ease of Maintenance • Controls Monitor Temperature, Pressure, and Conductivity of Cooling Liquid DC Link Choke

  9. Underground Mining Equipment VFD Motor Controls • Face Conveyor and Stageloader Applications • Torque and Speed Control • Enhanced Overload Capacity

  10. Underground Mining Equipment VFD Motor Controls • Allows Face Conveyor to Operate at Reduced Speeds: • Minimizes Chain Wear by up to 40% • Reduces Energy Costs • Extends Time Between Rebuilds

  11. Underground Mining Equipment VFD Motor Controls • Extreme Overload Capabilities: • PowerFlex 7000 Kit May be Customized • Normal Duty at 110%, Heavy Duty at 150% • Mine Duty up to 280% Overload for 20 Seconds of Each 120 Seconds • 6.6 kv Rectifiers with Oversized DC Link Choke and Input Line Reactor

  12. Underground Mining Equipment VFD Motor Controls • Modular Liquid Cooled Design: • Used in Multiple Motor Configurations, Add or Remove Motors as Required • Separate Controls in Skid or Wall Mounted Configuration • Closed Loop Liquid Cooling System Keeps VFD Cooler and Cleaner for Increased Life and Reliability • Motor Leads Up to 10 KM

  13. 4160 Volt VFD for Underground Belt Conveyor Controls • Modular Design Provides Flexibility in Number of Motors Used • Main or Booster Applications • Torque and Speed Control

  14. 4160 Volt VFD for Underground Belt Conveyor Controls • Unlimited Conveyor Start Time Minimizes Belt Tensions: • Minimizes HP Required and Conveyor Component Sizes • Reduces TakeUp Requirements • Extends Belt Life

  15. 4160 Volt VFD for Underground Belt Conveyor Controls • Allows Conveyor to Operate at Reduced Speeds: • When Less Than Design TPH is Required Conveyor Speed May Be Reduced • Belt Inspection Speed for Maintenance

  16. 4160 Volt VFD for Underground • Modular Liquid Cooled Design: • Used in Multiple Motor Configurations, Add or Remove Motors as Required • Separate Belt Controls in Skid or Wall Mounted Configuration • Closed Loop Liquid Cooling System Keeps VFD Cooler and Cleaner for Increased Life and Reliability

  17. 4160 Volt VFD for Underground • Lowers Electrical Harmonics: • Active Front End Provides Regenerative Ability • Active Front End Meets IEEE-519 Requirements • SGCT Devices Use Slower Switching Frequencies Reducing Common Mode Noise • Eliminates Need for Drive Isolation Transformers • Eliminates Harmonics Damage to Electrical Distribution Equipment • Motor Lead Lengths Up to 10 KM

  18. 4160 Volt VFD for Underground • Reduces Installation Cost of Low Voltage: • Saves on Cable Cost • Smaller Cables Reduce Installation Time • For 400’ of Cabling: • Saves Over $70,000 in Cable Cost • Requires Less Than 1/3 of Time to Install or Move
