Re: Beware of estimates from Marketing

@MWagner, Trinamic is still a smaller player.  Other players include TI, ST, Allegro Microsystems, NXP/Freescale, Microchip, Altera, Xilinx, and more.  And of course, a motor (especially a stepper motor) can be controller by a chip that's not a dedicated motion chip.  So maybe the sum of all these equals 3 billion.

I've been aware of Trinamic for years and some of their products do look interesting, but I haven't used any of their products; given our low volumes, at work we always use commercial drives, and Trinamic's drives aren't a good fit.

TI and ST are also trying to make stepper and servo control much easier (both with a variety of integrated drive chips and software/firmware with easier servo tuning).

Given the computational speed of modern MCU's and DSP's, and the slow (mechanical) response time of motors, I'd say that neither FPGA's nor hardware algorithms are required for good motion control.  BTW, fast motors are fun -- my personal best is 20,000 RPM on a NEMA 23 servo motor.

Beware of estimates from Marketing

I think their estimate is a little inflated: "$50 million in revenue last year, it anticipates 20-percent sales growth in 2017. Randt estimates that 3 billion motors are being driven by chips".  Even at $1/chip that is only 50million motors.... am I missing something here?
