## Description

THIS DRIVE WILL NOT OPERATE WITHOUT A PLUG-IN HORSEPOWER RESISTOR. Horsepower resistors are available for purchase. KBMD-240D Multi-Drive - NEMA-1 SCR Drive The Model KBMD-240D, also called Multi Drive, is a packaged SCR drive in a NEMA-1 enclosure. It utilizes the KBMM speed control for its electronics. The Multi-Drive is rugged and compact in size. It handles both 115 and 230VAC line inputs by setting the built-in Dual Voltage Switch. In addition, the single model can be used on a wide range of motor horsepower by inserting the appropriate Plug-in Horsepower Resistor. The Auxiliary Heat sink (optional) increases the rating of the basic unit. An optional Forward Brake-Reverse Switch Kit is also available.

Review: Mini-lathe motor controller!! - High quality DC motor controller! Purchased this to operate my Grizzly G0765 mini lathe who's board burned up. I cannot say enough good things about this controller. Very smooth operation and runs very cleanly. The fine tuning pots allow the user to dial in all the necessary parameters for stop, torque, startup, etc. I'd go as far to say simply get rid of your mini lathe controller and just install this. The build quality of the board and components are several steps above. Simply a fantastic unit.
Review: Works well, very pleased - I purchased this to put on a Rockwell/ Delta wood lathe. It's an older lathe, and I wanted to give myself some of the updated options of todays lathes(forward / reverse / variable speed). I also added a DC reversible motor. With these additions, I have the ease of maintenance of the older lathes and the variable speeds / reverse options of the newer models.

### ⭐⭐⭐⭐⭐ DC Motor Controller
*by W***N on October 25, 2025*

Great controller. I use this to replace my original controller on my Big Dog mill and lathe. Both machines used to same control boards that are in this controller, but stuffed inside oem housing. I wanted to just get rid of the oem housing and go to something simpler. Super easy to install and modify to fit machine. I did have to make adjustments to pot settings. Took seconds to adjust to my liking. Shipping was quick. Had it in 3-4 days. What more can you ask for. Thanks
