Abstract
An electric motor device for powering a tool clamp, for example a resistance welding clamp, of the type comprising a casing of an electric motor the shaft of which is connected to the clamp, to control the electrodes for opening, closing and clamping them onto a metal sheet, by a system of the through-the-motor type which converts the rotary motion of the shaft into translational motion of a mechanism operating the clamp, this motor being linked to a control variator and a slaving device coupled to the rotor of the motor. The device being arranged at the end of the motor shaft, the shaft is fitted with a gear wheel which can be operated from the outside, for rotating it manually, through at least one opening in the casing offset with respect to the motor shaft.
