Saminco VFD Closed Loop

Saminco's Variable Frequency Drive, closed-loop propulsion systems for mining vehicles, provides precise position, speed and torque control to allow mining vehicles such as Continuous Miners, Shuttle Cars and Scoops to maintain electrical-powered stand-still on a slope without requiring the use of mechanical brakes.

Saminco Testing Battery/AC VFD System for Battery Haulers

See our Video
Testing will be complete soon on the new Battery/AC Variable Frequency Drive system for Battery Haulers.  Available at 128V or 240V, this system is a retrofit installation sized for existing xp boxes with dual voltage motors (128V or 240V) which will mount within existing framework, using existing gear reducers and planetary wheels.

Current testing confirms tram motors are working smoothly with speed frequency running from 90 Hz to 150 Hz.  The Turbo Torque™ traction drive is delivering superior stall torque and top speeds.  Tramming has stayed strong when moving through wet, mushy or sandy ground, especially when cornering.    The Whisper Pump™ on-demand hydraulic pump drive system has also proven very successful in early tests as it reduces DC current draw on the battery during idle periods and then immediately increases rpm speed with hydraulic pump demand.  This has significantly reduced pump noise during idling, allowing extended exposure time for miners.

The new VFD system will fit in xp boxes with a minimum size of 35.5” (902mm) W x 15.75” (400mm) H x 25” (635mm) D.  The system is sold complete with tram and pump drives, a master control module, dual voltage motors and all accessories.  SWAP team services are available for inspection and installation.  Contact your Saminco salesperson for system specifications and requirements.
