    摘要： A hybrid drive system (600) can include a shaft (601), an electrical machine (603) comprising a rotor (605) and a stator (107), and a mechanical disconnect system connecting the rotor to the shaft. The mechanical disconnect system is configured to mechanically connect the rotor to the shaft in a first state and to mechanically disconnect the rotor from the shaft in a second state such that rotor does not drive the shaft or such that the rotor is not driven by the shaft. The rotor can be a permanent magnet rotor, for example.

    摘要： The present disclosure provides an electric motor and an elevator system. The electric motor includes: a casing; a stator supported by the casing, the stator including a stator yoke and stator teeth (261), and a winding (28) being wound around the stator teeth (261) and generating a magnetic field when energized; and a rotor which rotates under the action of the magnetic field; wherein at least a portion of the stator yoke is formed as a moving plate (3) which is movable between a first position and a second position; and when the winding (28) is energized, the moving plate (3) is capable of moving from the first position to the second position under the action of the magnetic field, and in the second position, the moving plate (3) is separated from the rotor; and after the winding (28) is de-energized, the moving plate (3) is moved from the second position to the first position under the action of a spring force, so that the moving plate (3) comes into contact with the rotor to provide a braking force to the rotor.

    摘要： A rotary drive includes: a support structure; and a linear actuator supported by the support structure. The linear actuator includes: a first member; a second member that moves in a linear direction relative to the first member when a drive signal is applied to the linear actuator; and a bearing arrangement supporting the first and second members within the support structure and enabling independent movement of the first member and the second member relative to the support structure. The rotary drive also includes a linear-to-rotary converter to which the second member of the linear actuator is coupled. The linear-to-rotary converter includes an output member having a rotational axis. During operation, the linear-to-rotary converter converts linear reciprocating movement of the second member of the linear actuator to rotary movement of the output member about the rotational axis.

    摘要： Electric energy eolian generator, made of relatively limited sizes, particularly for installations on inhabited environments, adapted to operate also under conditions of strong wind. Generator comprising a rotating rotor (6) supported by a support structure (7) and adapted to support the rotating vanes (60) and the electric energy generator (42, 43), connected mechanically to the vanes (60) and actuated in rotation by the rotation of the same vanes, for generating the electric energy. Generator in which the rotor (6) is supported articulated by means of support and articulation means (21; 111; 123), an end portion of which is pivoted to both the rotor (6), through leverage means (29, 30), and the upper end portion of the support structure (7). There are also described in detail the structural configuration of the rotor (6), the electric generator (42, 43), and the vanes (60) and further component parts of the eolian generator, as well as the operation of this latter.

    摘要： A generator (5) for a wind turbine (1) is disclosed. The generator (5) comprises a rotor (3) configured to rotate about a rotational axis, and at least one stator (4) arranged next to the rotor (3). Each stator (4) comprises at least two subunits (8), the subunits (8) being arranged side-by-side along a moving direction of the rotor (3). Each subunit (8) comprises at least one flux-generating module (9) facing the rotor (3) but spaced therefrom, thereby defining an air gap between the rotor (3) and each flux-generating module (9). The subunits (8) are movable relative to each other along a direction which is substantially transverse to the moving direction of the rotor (3). This allows a subunit (8) to move in a manner which adjusts the air gap without affecting the position and the air gap of a neighboring subunit (8). Thereby variations in the rotor (3) can be compensated and a uniform and constant air gap can be maintained. The invention further provides a wind turbine (1) comprising such a generator (5) and a method for performing service on a generator (5).
