  • Rotator arrangement with an angle meter
    Patent number: 10808380
    Abstract: A rotator arrangement (10) comprising a motor (11) with a stator (13) and a rotor (12) arranged inside the stator (13) to rotate with respect to said stator (13) around an axial axis (A). The rotator arrangement (10) comprises a rotor attachment piece (15) connected to the rotor and a stator attachment piece (16) connected to the stator, wherein one of the rotor attachment piece (15) and stator attachment piece (16) is arranged to be attached to a crane arm or the like, and the other is arranged to be attached to a tool implement. An angle meter (17) is arranged to continuously monitor the rotation of the rotor (12) with respect to the stator (13), wherein the angle meter (17) comprises a stator part (18) that is arranged to rotate with the stator (13) a rotor part (19) that is arranged to rotate with the rotor (14), and wherein the angle meter (17) is arranged along the axial axis (A).
