New Variable Frequency Drive (VFD) and VFD Plus kits from Servo

By Mike Santora | July 7, 2020

VFDPlusSERVO Products Company (Eastlake, OH), a progressive designer and manufacturer of a broad line of manual knee-type milling machine accessories since 1964, recently introduced designer and manufacturer of a broad line of their new Variable Frequency Drive (VFD) and VFD Plus kits which 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. 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.

• (50-500 RPM & 500-5,000 RPM)
• torque throughout the entire RPM range
• 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

VFD.1Made 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 convenient package, it can go up to 5,000 RPMs in high gear–10-15% higher than the standard milling. Providing all the torque you need in a machine could do. Unlike early VFD kits, these provide full-torque at the lowest RPM.

SEMI-AUTOMATED TAPPING FEATURE: The tapping function uses a proximity switch to reverse the spindle at the user set depth to automatically reverse the spindle, and back out of the tap. Once the spindle goes back to the top position, the spindle then turns forward, ready for the next tapping cycle. You simply put the drill in, and then set the speeds; i.e.-push-button “1” at drilling speed, then set push button “2” at a tapping speed. This allows you to run through a desired sequence at the right RPMs.
