ABSTRACT:
This invention relates to a monophase electromagnetic rotary actuator of angular travel between 70/N and 110/N degrees exhibiting a high torque/mass ratio and a torque that is approximately independent of the angular position of the rotor. A relation between the magnetized width Y.sub.a measured on the mean diameter of the magnets, the width of the angular arc C through which the rotor passes on the mean diameter of the magnets, the width S measured on the mean diameter of the magnets between two adjacent stator poles, the radial length of the magnets L, and the constant length E of the air gap is:
