VFD Converting Kits

Variable speed components on milling machines typically wear out within 5 to 10 years and will need to be rebuilt—which could represent thousands of dollars for a stop-gap repair. Unique to the market, there is now a one-time, alternative solution that completely eliminates a machine’s needless sliding variable speed pulley components–providing an ultra-reliable, long-term fix.

The Variable Frequency Drive (VFD) and VFD Plus kits are full-featured packages designed to convert older step pulley mills and variable speed mills from mechanically controlled speed, into an electronically controlled machine.

The complete VFD kits are “plug-and-play” solutions that are easy to install and easy to operate–quickly upgrading a mills reliability, versatility, and productivity with smoother variable electronic speed control.

Made in the USA, both VFD kits are also suited for smaller garage/machine shops, mills, lathes, and grinders.

Adaptable to most applications, the VFD kits can run the motor on 220V single-phase incoming power vs. requiring three-phase power–eliminating the need for a phase converter. Providing all the torque you need in a convenient package, it can go up to 5,000 RPMs in high gear–10 to 15% higher than the standard milling machine could do. Unlike early VFD kits, these provide full-torque at the lowest RPM.

Notably, both VFD kits feature a red E-Stop button that milling machines typically do not have. There is also an E-Stop safety circuit to prevent accidental start-ups.

  • Two RPM Ranges (50 to 500 RPM & 500 to 5,000 RPM)
  • Full torque throughout the entire RPM range
  • Accurate in both gear ranges
  • Can run a three-phase motor with single-phase input (up to 3 hp) 
  • Sensorless vector control
  • Includes all mounting hardware
  • Spindle rotation is always correct
  • Bright Blue LED Display that is truly accurate in both gear ranges
  • 10 Turn potentiometer for accurate speed control
  • Integrated dynamic braking resistor for quick forward/reverse changes (like tapping applications)
  • There is a window to view the VFD status
