2 HP 1500 Watt Computer Controlled Servo Motor With 2024 control unit.
Built to fit Bolton B290VG

Please note:
The back of the control unit must be open to atmosphere to allow for cooling.
Optionally it can be thermally bonded to any large metal surface. Then the surface
becomes the cooling system.

Look close should fit similar Precision Mathews

Custom Built When You Order:
Lead time is up to 5 days.


Comes with a custom made 2 step pulley designed to match the OEM belt and pulley.
See new 2024 version anodized in red pulley images.
These are custom made by us and a direct fit to our motor as well as to this lathe.
Also greatly reduces runout and or vibration.

Sold with a custom built 2024 control unit:
Includes reverse on the fly and more.
Speed is programmable for any range between 300 to 3,500 RPM.


Current motor face mount design: 
Allows for our servo motor to be installed in the original location. 
On the Bolton lathe in images, it's simple, just widen 2 of the four slots a little bit.
See You Tube video

Runs on typical 110 to 120 volt AC household power supply's

Motor programming + spindle speeds and Reverse:

  • The motor speed can be programmed to operate in any range chosen by the user.
    Between 200 and 3,500 RPM's.
    Note: Settings are limited to 10 RPM intervals.
  • The full range of speed (RPM's) can also be controlled with just the speed control knob.
  • Speed control programming only requires a few easy steps.
  • Reverse is simple, just hold the yellow button for a few seconds.
  • Programming includes the ability to set bottom and top RPM range separately. In other words you can program the system to run the spindle at any speed or range of speeds you choose (see below).
    Slowest speed achievable: Motor 200 RPM. (Below 300 is not recommended).
    Highest speed: 3,500 RPM .
  • Soft start is programmable and will be set as soft as possible when you receive this motor. This program is very effective in reducing drive belt wear etc.
  • Braking strength is also programmable and will be set as low as possible. Personally I wish I could set it lower.
  • Self diagnostics with fault code chart and programming instructions are available on our web site.
  • Safe turn on system. If the power goes out, the speed control knob must be returned to stop
    before the motor will run.. When turned on the self
    diagnostic system checks for faults and will not allow the motor to run until the speed control knob is turned all the way to stop first.
  • Remote stop/start without self diognostics step above is possible. This is a use at your own risk
    function made possible for those wishing to instal a trigger, travel or CNC switch.
  • Use at your own risk. Our liability is limited to the purchase price of this item.
