Problems solved by technology

As an example, in the case of a permanent magnet synchronous motor or a synchronous reluctance motor, the power electronic components of the electric drive, such as controllable semiconductor switches and diodes, may cause high currents to flow through these power electronic components during long periods of zero speed of the electric motor , which may overload the part

Embodiment Construction

[0017] figure 1 A simplified diagram of a winch arrangement according to an embodiment is shown. figure 1 The exemplary winch arrangement of ® can be used, for example, to moor a vessel. The drawing shows only the components necessary to understand the various embodiments. An exemplary winch arrangement includes a winch drum 20 for winding the spoolable medium 10 , the winch drum being rotatable about an axis of rotation 21 . Windable medium 10 may comprise, for example, a cable, rope, wire, chain, or combinations thereof. exist figure 1 In an example, the winch device further includes an electric motor 30 , which is operatively coupled to the winch drum 20 such that the winch drum can rotate together with the electric motor 30 . The electric motor 30 may be directly connected to the winch drum 20, or connected to the winch drum 20 via one or more other components or devices, such as a gearbox (not shown). The electric motor 30 driving the winch drum 20 may be of any type...

Abstract

The present application discloses a method, electric drive, computer program product and winch apparatus for operating a winch comprising: a rotatable winch drum (20) for winding a spoolable medium (10); and an electric motor ( 30), which is operatively coupled to the winch drum. The electric drives (40, 41) are configured to: drive the winch drum (20) by driving the electric motor (30) so that the tension of the windable medium (10) reaches a predetermined tension set point value or range of values ​​and will setting the driving speed of the electric motor (30) to zero; and after setting the driving speed of the electric motor (30) to zero, driving the electric motor (30) at a predetermined driving speed to alternate rotation directions such that the rotation directions are Scheduled frequency changes.

Description

technical field [0001] The invention relates to operating a winch, and an electric drive for driving the winch. Background technique [0002] Winches can be used in conjunction with many applications. Examples include mooring winches, ramp winches or marine traction winches. Such a vessel may be, for example, a vessel, steamer or general vessel designed for water transport in seas, oceans, lakes, rivers, rivers, waterways or any part thereof. [0003] A winch may comprise a winch drum rotatable about an axis and for example for winding a windable medium such as a cable, rope, wire or chain. In the case of winches for mooring, for example, a windable medium would be connected between the vessel and the mooring point. The winch can be located in the vessel or in the mooring point. A mooring point may eg be any point at which a vessel can be moored, such as a mooring post at a vessel unloading location such as a port or quay, or an anchor or a buoy. For example, such a win...
