ABSTRACT:
A speed governor, for internal combustion engines, with an electromechanical adjustment member for adjusting a butterfly valve or an injection pump, an electronic speed receiver, and an electronic control member. The adjustment member has a stationary part with coils, and a part, with a permanent magnet, rotatably journalled in the stationary part, with the magnetic field of the magnet passing through the coils; the permanent magnet is arranged in such a way that a torque of predetermined magnitude and direction is effective thereon during current flow through the coils. The permanent magnet may be embodied as an at least two-pole, axially magnetized ring with a first laminated-iron ring as a magnetic return, and the adjustment member may be provided with at least two stationary, evenly wound, sector-shaped coils and a second laminated-iron ring as a magnetic return. The permanent magnet may be cylindrical and in two poles, as well as being radially magnetized, with two stationary coils surrounding the permanent magnet in a plane parallel to the rotary axis, and a stationary iron tube being provided as a magnetic return.
