1. Try checking to see if the carbon brushes are worn (i.e. carbon deposits on the commutator)
2. Try securing the motor in a vice or similar and plug it directly into a 240V supply (Check the voltage first of the motor on the serial No plate)
3. Check you are getting a Analogue DC voltage of betweem 1v - 10v when the spindle is running and you vary the speed. Terminals 1 and 2 on connector TB7 on the botton left hand side of the Baldor drive board with the orange connectors and 7 segment display
