Abstract

See full text

The disclosure relates to methods and tools for handling a component, the tools (10) comprising a first clamp seat (12) for receiving a first surface of the component and a second clamp seat (14, 16) for receiving a second surface of the component, the second surface being opposite to the first surface. The tool further comprises an actuator (45) for moving the first clamp seat to clamp the component between the first clamp seat and the second clamp seat with a predetermined clamping force, and an electric motor (40) for driving the actuator (45). The tool (10) further comprises a control configured to determine currents in the electric motor and to control the electric motor to provide the predetermined clamping force based on the determined currents. Also methods for determining a desired current level in an electric motor driving an actuator for clamping a component and methods for controlling a clamping force in a tool are provided.
