Why Your Plant Still Struggles with Conventional Motors

  • 🔧 High electricity bills: Fixed‑speed drives waste up to 30 % of energy on start‑up and overload.
  • ⚙️ Frequent maintenance stops: Mechanical wear from abrupt starts leads to + 15 % downtime annually.
  • 📈 Poor process control: Inflexible speed limits reduce product quality and limit throughput.
  • 💰 Capital over‑spend: Over‑sized motors are bought to compensate for inefficiency, inflating CAPEX by 20‑25 %.

According to the 2025 International Energy Agency report, factories that adopt VFD technology cut overall motor‑related energy consumption by an average of **37 %**.
