Making room for smaller devices: The benefits of miniature motors

Author : William Mason, maxon UK and Ireland

30 November 2022

The trend for miniaturisation continues to be relevant, as many industries are driven to reduce weights and footprints in order to save space and improve user experience. Modern surgical tools, for example, are being made smaller and lighter to improve precision, while enhancing user comfort and safety.

Here, William Mason, Managing Director of maxon UK and Ireland, discusses how small motors are driving innovation across three sectors: medical, intralogistics and aviation.

Medical devices vary greatly in size and weight, from active implants, weighing between 20 and 50g, to larger, heavier surgical tools. Because of this, each device will have its own motor requirements. For example, active implants must withstand the high salt concentrations inside the human body. Meanwhile, surgical tools need motors with high-power densities and without gears, to limit vibration and noise.

Despite these differences, one thing remains the same: the need for small motors. In fact, it is now possible to manufacture motor controllers smaller than a postage stamp, adding extra control modules where necessary to enhance the capabilities and precision.
