Three-phase speed control
Variable Frequency Drives
AC drives supplied, installed and programmed. Speed control for building automation, pumping, irrigation, and water and wastewater plant.
A drive earns its keep before the motor ever slows down.
We sell, install, program and service AC drives, and we are a leader in the field of AC variable frequency drives in this shop. A VFD controls three-phase electric motor speed, and we put them to work across building automation, industrial, pumping, agricultural, irrigation, and water or wastewater applications. We stock TECO Westinghouse A510, E510 and F510 drives on our own rack, certified with Teco Westinghouse and other leading manufacturers, so a drive is often available the same day rather than back-ordered.
What a drive changes about the rest of the system
Slowing a motor down with a drive instead of a mechanical control changes more than the speed. It changes what wears, what costs to maintain, and what the demand charge looks like when the motor starts. The full list of what that buys you is below.

Seven reasons a drive earns its place.
What it costs to run
- Reduces energy costs
- Reduces amps during motor starting, lowering demand charges
- Less expensive to maintain than mechanical controls
What it does to the machine
- Inherent soft-starting reduces wear and tear on motors, sheaves, belts, couplings and other system parts
- Offers greater motor and application protection
- Reduces fan noise and duct rumble
- Provides accurate and repeatable control of HVAC settings, eliminating frequent readjustments
A drive controls the same range of motor we rewind and rebuild on the shop floor, fractional horsepower through 1000 HP, so application, installation and start-up gets handled by the people who also service what the drive is running. Call (405) 235-9638.
