Abstract

A pulse motor for clockworks and the like in which the rotor comprises two spaced-apart permanent magnetic disks mounted upon a common shaft and rotatable with respect to a stator. The stator comprises a respective pair of magnetic poles in the plane of each disk, the poles of the pair being interconnected by a shank and a coil wound upon the respective shanks, the coils lying on opposite sides of the rotor. The coils can be excited independently to cause the respective pair of poles to magnetically cooperate with the respective disk and rotate the motor in the forward or the reverse sense.
