Motor Control

Motor control refers to the process of regulating the speed, torque, and direction of an electric motor. In today’s applications, the most efficient and effective way to achieve this is through a Variable Frequency Drive (VFD). A VFD controls a motor by adjusting the frequency and voltage of the power supplied to it. This allows for smooth acceleration, deceleration, and precise speed regulation, ideal for systems where performance, energy efficiency, and equipment protection matter.

Phase Technologies offers a wide selection of single-phase and three-phase input VFDs to meet your specific motor control needs. Whether you’re working in a remote area with only single-phase power or running large equipment in a commercial facility, we have a VFD that fits:

Low Harmonic Series VFDs - Phase Technologies' Low Harmonic VFDs are engineered to meet IEEE-519 compliance without the need for external filters or additional components. By actively reducing total harmonic distortion (THD), these drives deliver clean, efficient power. Ideal for industrial, commercial, and utility applications, our low harmonic drives combine precision motor control with superior power quality.

Residential Series VFD’s - Phase Technologies' Residential series VFDs offer quiet, efficient motor control for home and light commercial applications where only single-phase power is available. Compact and easy to install, these drives are perfect for residential wells, HVAC systems, and small pumps. They provide soft starts, energy savings, and built-in protection, bringing industrial-grade reliability to residential settings.

Using a VFD gives you complete control over your motor’s operation. Rather than running at full speed all the time, a motor paired with a VFD can ramp up slowly, run at the exact speed needed, and ramp down safely, reducing wear and tear on mechanical systems and improving energy efficiency. VFDs are especially valuable in applications like pumps, fans, conveyors, and compressors, where load demands vary and energy savings are significant.

Other benefits include:

Reduced inrush current at startup

Improved process control

Extended motor life

Lower operating costs

Protection against voltage imbalance and phase loss

VFDs from Phase Technologies are designed to control standard single-phase and three-phase AC induction motors, which are the most commonly used motors in industrial and commercial applications. Many of our drives can also operate permanent magnet motors and EC motors with proper configuration. From irrigation pumps and saws to compressors and HVAC systems, our VFDs are trusted across a wide range of industries.
