Mesa Electronics 3C20:100W servo-motor controller suits brush motors with quadrature encoders

Targeting brush motors running at less than 100W with quadrature encoders, the 3C20 digital-motion controller claims a 32-bit or greater precision in position, velocity and acceleration, and jerk parameters. This DSP-based, the single-axis dc servo-motor controller/amplifier features a 30-MIPS, 16-bit DSP and a 100W H bridge. The device has a trapezoidal-profile capability and provides time-based S-curve profiles with a sequence of jerk values and delay tokensin the FIFOs. Measuring 2×2 in., the 3C20 digital-motion controller costs $54 (100).
