V*S Master Motor Saves Thousands in Avoidable Costs

This ABB case study highlights how a mining company replaced an inefficient hydraulic drive system with a Baldor-Reliance® 25 HP V*S Master motor. The upgrade delivered significant cost savings—nearly $90,000—by reducing downtime, improving efficiency, and eliminating the need for a costly hydraulic alternative.

Key Points

  • Mining operation’s feeder ran too fast even at minimum VFD speed (6 Hz).
  • The motor installation cost just over $3,000 versus $90,000 for a hydraulic system.
  • The V*S Master motor provided continuous full-load torque from zero to base speed.
  • Documented by ABB Motors and Mechanical Inc., Fort Smith, AR (2022).
  • Replacing with a Baldor-Reliance® 25 HP V*S Master motor allowed operation down to 1 Hz.
  • ABB’s analysis revealed total savings of $89,292 across purchase, operation, and downtime.
  • ABB’s consultative approach ensured a reliable, cost-effective solution for variable speed applications.
