NOVEL DUAL-STATOR COMPOSITE MOTOR SUITABLE FOR ROTOR ABSOLUTE POSITION SENSORLESS CONTROL

A novel dual-stator composite motor suitable for rotor absolute position sensorless control, relating to the technical field of motor device manufacturing. An inner stator (5) is fixed on a stationary shaft (9), an outer stator (7) is concentric with the inner stator (5), and the components above constitute the stationary part of the motor; a rotor (6) is mounted between the outer stator (7) and the inner stator (5), and forms the rotating part of the motor by means of a front rotor support (4) and a moving shaft (1); the rotating part is isolated from a front end cover (2) by means of a front outer bearing (3), and is isolated from a rear end cover (14) by means of a rear outer bearing (11) after being connected to a rear rotor support (10); the moving shaft (1) and the stationary shaft (9) are isolated by means of an inner bearing (13). The motor radially integrates motor structures of different types and having different numbers of pole pairs; sensorless detection is performed on the electrical angle posit
