4.1.2.6 Multi-pole resolver
Description
The number of sine and cosine periods per revolution corresponds to the number of pole
pairs of the resolver. Resolvers can detect relative motion. The absolute position within one
resolver output signal period can be determined.
Function and technical data
● Angular measuring system for the commutation
● Speed actual value sensing
● Indirect incremental measuring system for the position control loop
