Micro motors, as the name suggests, are extremely small electric motors that can be used in applications where space and weight are critical constraints. Some key facts about nanomotor:

- Nanomotor are usually less than 1 cubic centimeter in size. Many are less than 5mm in diameter and 5mm in length.

- They operate on relatively low voltages, usually less than 10 volts, which makes them ideal for battery-powered devices.

- Nanomotor draw very little power, sometimes as low as a few milliwatts. This allows for extended battery life in devices that use nanomotor.

- Precision manufacturing techniques are used to build Micro Motor with dozens or even hundreds of miniature parts. Micro-scale 3D printing is now enabling even smaller nanomotor.

Applications of Micro Motors

The precise size and power characteristics of nanomotor open up a wide range of applications. Here are some of the major uses of nanomotor:

Mobile Devices and Wearables

Nearly every mobile phone, tablet, laptop and wearable device uses nanomotor. Applications include vibrating alerts/haptics, auto-focus and zoom functions in cameras, cooling fans, and movement of internal components. As these devices continue to shrink in size, nanomotor play an increasingly important role.

Medical Devices and Equipment

A variety of medical tools such as surgical drills, dental tools, insulin pumps, and even miniature robots for medical procedures employ micro motors. Their small size allows non-invasive or minimally invasive medical treatments.
