Application Notes
- Using the AMC1210 in Resolver Motor Control SystemsPDF, 256 Kb, File published: May 18, 2006
Resolver motor control systems typically have used either closed-loop Resolver-to-Digital Converters (RDCs) or open-loop Analog-to-Digital Converters (ADCs) to obtain position and velocity data from the resolver outputs. TI has developed a new method of resolver decoding using the dual delta-sigma modulator ADS1205 and the AMC1210, a digital filter device designed specifically for use in motor con - Closed-loop motor control: An introduction to rotary resolvers and encodersPDF, 716 Kb, File published: Apr 11, 2014
