Optimising compact linear motion applications with mini motors

To achieve maximum performance from a miniature linear motion application, it's vital to make sure the motor's specification meets the requirements. Efficiency, high power, optimised dimensions and acceleration are among the criteria for selection, to optimise demanding lead screw applications. Clémence Muron, Application Engineer at Portescap, explains how to make the right choice.

Requirements for linear motion miniature applications range from filling syringes through to medical devices, or robotic applications used in the operating theatre. The first consideration for a design engineer is the method used to transfer the rotary motion of a miniature motor into linear motion.

The most common way of achieving this is by mounting a screw and nut system on the motor shaft. It operates on a rolling contact between the nut and a screw, which can provide low friction, good efficiency, and high load capability. The disadvantages, however, are the cost and the time to design such a solution, especially for applications that don't require high load handling.
