The ULT Series direct-drive, frameless motors now offer even larger through holes. Driven by applications in camera vision systems, the series offers some of the thinnest radial cross-section motors available. Initial sizes include 2.5” and 4.5” diameters. The motors operate using standard three phase brushless dc or brushless ac drivers with voltage ranges from 12V to 300V. Hall device options are also available. APPLIMOTION INC., Loomis, CA.
