Binary Position Sensor for Synchronous Machines based on a Serial n-bit Sequential Code

摘要

This work presents the design of an absolute position encoder with n-bit resolution based on a serial sequential. code to measure rotor position in synchronous machines. The encoder is capable of define 2~n positions minimizing the sensor disc size compared to conventional gray encoders and using the same hardware. Besides, a new approach to single-track code generation is proposed with the development of a code generation program. This design is going to be installed into an experimental hybrid vehicle helping in startup synchronization between the generator and combustion engine.
