Electromechanical drives for franking machines

摘要

An electromechanical drive for a franking machine comprises a module in which an electic motor controlled by an electronic circuit formed on a printed circuit board is manufactured as a modular unit by mounting the motor, mechanical drive components and a position sensor on the substrate of the printed circuit board. This module is mounted on a further module consisting solely of mechanical components and the drive components of the two modules are thereby drivingly engaged. This construction leads to economies in manufacture and ease of servicing because no electrical connections are required between the modules and hence assembly and dis-assembly of the circuit board and mechanical component module are made easier.
