Abstract

A device for applying a force, such as a clamping device, comprises an electric motor (2) which, when energised, causes rotation of a nut (8) which in turn causes linear displacement of a spigot (9) and of an output element (16). When the output element (16) meets a resistance and is arrested, a resilient assembly (15) is compressed, and relative movement takes place between a rod (17) carried by the output element (16), and a tube (18), carried by the spigot (9). This relative movement is detected by a transducer (20) which, when the movement reaches a predetermined value, delivers a signal which causes the motor (2) to be de-energised. The device enables a predetermined clamping force to be achieved and maintained substantially constant, or varied in a predetermined manner. The device may be used on machine tools. <IMAGE>
