    摘要: A drive arrangement for an electronic time-keeping device in which a rotor member is juxtaposed with a stator member, one of the members being provided with a pair of coils including a sensing coil (pick-up coil) and a drive coil. The other member carries a pair of oppositely poled magnets cooperating with the coils. A NPN transistor has a collector-emitter network in series with the direct-current source and the drive coil while the sensing coil is connected in a base-collector network of the transistor.
