That drive motor looks like the ones I have - 4HP and you need a Focus 5hp dc driver for it. There also is a 90v dc brake that you have to release before turning it on. Grab the spindle and try to turn it, make sure the lock pin isn't in and you'll see. The little rectifier in the original cabnet is used to operate this.
The alernative is replace the dc motor with a 5hp AC motor with an inverter contol. About $1200 job but will be easier to control and they last a lot longer than the dc job in there now. Also, no brushes to deal with and you eliminate the brake release control and timing problem.
Has anyone solved the turret indexing operation control and encoder feedback to artsoft control?
