Both Pico and Mesa do brushless motor drives that integrate well with their controller cards. That probably makes more sense than buying a smart drive and ignoring the smartness. Mesa have a bit of a gap between the 250W 7i39 (which connects to the 50-way header on the 5i20, 5i23, 5i22 or 7i43 boards) and the 8i20 (2.2kW) which connects via Smart-serial. You can connect 2x 7i39 to each connector on a 5i23, for example, for a total of 6 motors. A 5i25 with the correct firmware could control 16 8i20 drives. The Pico brushless servo amp is also a bit oversized for the motors you are suggesting (120V, 20A), but is somewhat cheaper than the Mesa 8i20. Keling seem to have a fair range of motors in a directly compatible size to your existing steppers: http://www.kelinginc.net/DCBrushlessMotor.html There is a HAL component that can handle any combination of motor output and amplifier input. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
