Built For
Heavy Industry.
From HVAC and machine shops to food & beverage and metalworking. General-purpose and low-harmonic VFDs, panel shop builds and motor protection engineered, built and tested in Rapid City, SD.
One Series. Every Industrial Load.
Industrial equipment puts different demands on a motor control system. Large motors, high starting torque, continuous operation and sensitive processes require more than a standard, off-the-shelf drive.
Phase Technologies provides VFDs, phase conversion, motor protection and custom control panels for demanding industrial applications. From HVAC and machine shops to food and beverage production, aggregate processing and metalworking, our systems are engineered to deliver dependable motor control, stable power and long-term performance.
Whether you are running a single machine or coordinating motors across an entire facility, our team can help configure a system around the load, incoming power, operating environment and control requirements of your application.
Every Phase product is engineered, assembled and tested in Rapid City, South Dakota. Our in-house engineering and manufacturing capabilities give us greater control over quality, configuration and delivery, helping industrial customers get the equipment they need without the extended lead times common with highly customized systems.
Applications
Commercial Building
VFDs and motor control for HVAC, pumping and building systems.
Manufacturing
Speed control for conveyors, presses and production line motors.
Aggregate
Rugged drives for crushers, conveyors and quarry equipment.
Data Centers
Low-harmonic VFDs for cooling in mission-critical facilities.
Power Generation
Drives and controls for turbines and generation support equipment.
Food & Beverage
Motor control for mixers, conveyors and pumps in food production.
When motor-driven equipment stops, the impact goes beyond a single machine. Production slows, labor is interrupted and maintenance teams lose valuable time tracking down the problem.
Phase Technologies helps industrial facilities build more reliable systems from the start. Drives, phase converters, starters, filters and protection products can be selected to work together as one coordinated package. That means fewer compatibility issues, simpler installation and a clearer path to support when questions come up.
From everyday speed control to low-harmonic and regenerative applications, the goal is the same: give your equipment the power and control it needs to perform consistently, shift after shift.

Phase Perfect is the only true digital phase converter made anywhere in the world. It uses active digital electronics to synthesize a genuine third phase, delivering balanced three-phase power that stays stable under load.
Others claim the title, but they are two-leg phase shifters. Rotary and static designs leave the generated leg unbalanced and unstable, and that shows up where it matters: motor heating, nuisance tripping, premature wear and wasted energy.
We build the real thing, and we are unapologetic about being the only one. Phase Perfect delivers the cleanest, best-quality three-phase power available for single-phase sites, so your equipment runs cooler, quieter and longer.
