"We’ve managed to pack quite a lot of power density in a small package." —David Ma, Yaskawa America
Semiconductor processing equipment is a notoriously demanding application for motion control engineers. Extreme precision, reliability and smoothness are absolute requirements. At the same time, space is at a premium.
And therein lies the problem. “Many times, when you need a motor for a small space, you have to make compromises,” says David Ma, technical project manager for Yaskawa America Inc. “Perhaps your encoder resolution isn’t precisely what you want, or maybe the power density isn’t what you want.”
