Transformation angle detector for electric machine with stator and rotor with transformation of currents and voltages from one system into another and vice versa, with sensor for detecting speed and rotor angle

摘要

Electric machine (20) contains stator (21) and rotor (25) and carries out transformation of currents and voltages from d,q system into R-S-T system and vice versa. Sensor (1) detects speed and angle (psi 1,0) of rotor position .Sensor is in form of reluctance resolver and is located in housing of machine. It comprises part (4), fixed in housing, and mobile part (3) on machine shaft (2) for detecting rotor position angle. Preferably fixed sensor part contains two secondary coils (5) and one excitation coil (7).
