Larken,
I have a Bridgeport boss R2E4 servo machine that has a dead control and I am in the process of doing a retrofit. I would like to use the Viper 200 card. I was wondering about the power supply.. and Heatsinking
the servo's on my machine are as follows:

powertron
permanent Magnet DC servo motor
Rated Torque: 30" pounds
Max Voltage: 146
Rms Amps: 14.6
Max pulse Amps: 58.3
Frame C402-3
Model 402CNSPOS72
Serial 15347

With a BEI encoder Mounted
Model 25G-250-ABZC-8803-sM18-s (150336-250)
Part Number 924-01029-092A
Date 11-1-84

Hey Jeep534:

I’m in the process of doing a similar retrofit. Using the Viper 200’s and I just went to http://toroid-transformer.com./ and emailed them my motor spec’s and they were very helpful. You might want to give them a try.

Yes, that motor is ok for the Viper 200.

For heatsinking, mount them on the edge or flat on 1/4 alum plate and have a fan blowing on them. At the higher voltages some of the power resistors for the voltage regulator need abit more cooling.

To get 146 volts DC, your transformer should output about 100 volts.

Jay,
I sent you a pm. It might be nice to share our misery as I just started gutting the cabinetts this evening.

Happy Hunting
