TLDR
In this article, a stepping motor for use in a remote register, such as is used for the remote reading of electricity meters, is arranged to be advanced by current pulses of known constant polarity.Abstract:
A stepping motor for use in a remote register, such as is used for the remote reading of electricity meters, is arranged to be advanced by current pulses of known constant polarity. The motor includes magnetic biasing means which effect further rotation of the rotor of the stepping motor in the same given direction each time that an input current pulse ends. The motor can therefore be controlled by a simple ON/OFF switch in the electricity meter circuit with a rectifier being provided in the remote register. The magnetic biasing means may consist of one or more cylindrical magnets co-axial with the rotor, or a straight or arcuate bar magnet adjacent to the periphery of the rotor.read more
