Motor position sensor, has resolver formed in motor, set of release coils wound around magnetic stator poles and corresponding to magnetic rotor poles, and main body rotor concentrically attached at motor spindle

摘要

The sensor has a resolver (10) formed in a motor (A), and a main body containing a main body rotor (11) and a main body stator (12). A set of magnetic rotor poles (111) is uniformly and centrally arranged in the rotor. A set of magnetic stator poles (121) is uniformly and centrally arranged in the stator. The poles (121) correspond to the poles (111). A set of release coils (20) is wound around the poles (121) and corresponds to the poles (111). The rotor is concentrically attached at a motor spindle of the motor.
