The IRAMX I am using is rated up to 16A at 600V, and designed for 0.75-2.2kW Motors. The motor I am using for development is a 400V 0.9kW Rexroth. Everything is still at a very early stage, I have not run my PCB at more than 50V as it still lacks fuses and overcurrent protection. It is split up into two PCBs, a power board with the iramx caps and optos, accepting 4 PWM signals, 3 phases and current, also acting as enable. The second PCB is on a stm32f4discovery, and accepts resolvers, differential encoders, rs485 and ethernet. It is designed to get the software development going, and is easy to build, 1 layer, and through hole components. I have a lot of thoughts on the interface to linuxcnc, but not implemented anything yet. Currently I am working on the current control, linuxcnc interface, and a version without the discovery board, only with stn chip. Someday it might also support DC servos, and async motors.
