摘要： An efficient direct current motor using a shell armature with toroidally wound coils thereon. The armature coils interact with two independent magnetic circuits. One magnetic circuit includes an inner magnet enclosed by the armature shell and radially magnetized. An inner magnetic core is disposed within the inner magnet and in direct contact therewith to form a return path. The second circuit includes an outer magnet radially magnetized oppositely to said radially magnetized inner magnet and enclosing said shell armature. An outer magnetic yoke is disposed outside and in direct contact with the outer magnet to form a return path therefor. The shell armature is disposed between the inner and outer magnet and adapted to rotate in response to interaction between the fields created by the two magnetic circuits and current in the armature windings.

摘要： A printed circuit resolver produces voltage outputs that vary according to sine and cosine functions with the angular position of a rotor winding. Each resolver winding is planar and comprises at least two planar multi-turn coils formed on a disk. Each coil comprises N turns and 2 M sectors, where N and M are numbers.

摘要： The contact spring (7) comprises two outer lamellar branches (71, 72) and two inner lamellar branches (73, 74) subjected to the action of a prebiasing member (6) integral with an actuating member. Two stationary stops (9, 10) are arranged on either side of a transverse connection portion (77) of the spring (7) and have each a plane contact surface extending at least throughout the length of the portion (77) and susceptible of extension throughout one portion of the length of the two outer branches of the spring (7). The actuation force, as well as the stroke of the prebiased spring, may be very important with respect to the size of the switch, the electric contact being suddenly established with an appreciable contact force.
