Bridgeport servo motor selection

[Davek0974]

Collin,

I am pretty sure the 750W is enough since you are going to gear it.

I did my BP conversion just over a year ago, all motors etc from BST on Aliexpress, great guy.

I used 750W AC servo with 2:1 reduction on X & Y, 400W with 2:1 reduction on Z, I still have not even made these motors warm up yet, I doubt a Bridgeport is going to be able to take a big enough cut to even bother a 750W motor.

My spindle is a 3kW investor rated motor, not a servo but I added an encoder and can do rigid tapping very nicely at lower speeds. Top speed is 4000rpm, bottom without back gear is 300rpm.

I am just adding another 750W servo to the knee so i can send it tool length compensation and keep all the quill travel for the work.

I'd like to convert my BP into a CNC milling. I'm not sure what I need... should I take servo motor with break. Do you have a liste of everything you had to buy for your BP?

Hi
no you do not need motors with brakes, just plain AC servo motors, I got mine on Aliexpress from China.

I do not have a list, sorry.

I found the AC servo motors 0.75kw 80ST-M02430 2.39N.M 3000rpm and Servo driver with Servo cable 80ST (750 W for XY and 400W for Z), the timing belt and pulley, I have the pc, what else do I need to make it work? Can you send me few pictures of your setup? My email is [email protected]
