A complete servo motor as seen in images.

A stand alone and programmable custom built 2026 version servo motor driver with overload protection and internal speed control.

A welded steel motor mount designed to fit the Smithy AT300 and Smithy CB-1220. Look close at images as some of these
machines have a different mounting system.

The pulley comes installed on the motor
The motor speed can be programmed to operate in any range chosen by the user.
Between 200 and 3,500 RPM's.

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 available on line.

Power out safety. Speed control knob must be manually returned to zero/stop after a power failure.
