Variable Frequency Drives
What is a Variable Frequency Drive (VFD)?
A VFD is an electronic device that controls the speed and torque of an AC motor by varying the frequency and voltage of the power supplied. By replacing fixed-speed operation with dynamic adjustments, VFDs eliminate energy waste, reduce mechanical stress, and enable smarter automation.
What Are Variable Frequency Drives
Key Features of Schneider Altivar VFDs:
Energy Savings: Reduce motor energy consumption by 30–50% by matching motor speed to actual load demands.
Soft Start/Stop: Gradually ramp up/down motor speed to prevent mechanical shocks and prolong motor/bearing life.
Advanced Control: Built-in PID controllers, PLC-like logic, and multi-motor synchronization capabilities.
Smart Connectivity: IoT-ready with EcoStruxure integration for remote monitoring, predictive maintenance, and data analytics.
Robust Protection: Safeguard motors from overloads, phase loss, voltage fluctuations, and overheating.

How VFDs Work
Convert AC to DC: Rectify incoming AC power to DC using a diode bridge.
Filter and Stabilize: Smooth DC voltage using capacitors.
Invert DC to Variable AC: Use insulated gate bipolar transistors (IGBTs) to recreate AC power at adjustable frequency/voltage.
Control Motor Speed: Adjust frequency (Hz) to regulate motor RPM, ensuring precise load matching.
