Depending on the design of the motor and the materials used, thermal phenomena will dictate the motor’s performance. Motor designers typically have two options to enhance motor performance without overheating and damaging its components: increase power conversion efficiency by generating less heat for a given mechanical power output or improve the motor's cooling capability through heat dissipation.

In applications requiring a large torque load at slow speeds, it is more economical to use a [gear motor](https://www.portescap.com/en/products/accessories/gearheads)(aka gearhead) rather than a large enough motor to provide the specified torque. The gearhead  is mounted on the front end of the motor and specific gearing provides the overall speed and output torque. There are[various types of gearhead](https://www.portescap.com/en/products/accessories/why-a-gearhead) technologies. Here, we will focus on Spur compound and Planetary.   Spur gears are designed with the concept of having only one transmission point per train.

Miniaturized electrical motors contain tribological components like sliding contacts (brushes), rolling contacts (ball bearings and bush bearings), damping rings, seals, washers and gears. These tribological components tend to fail before other components of the motor mainly because of friction and wear. Thus, life of the motor is very much dependent on the performance of the tribological components. Let’s look at a few tribological motor components which impact overall life.

With the improvement of a digital interface for adjusting aspiration or dispensing, electronic pipettes offer a huge advantage and relief from ergonomic methods. The motor is the key element in the design. When design engineers specify a motor    they must consider factors such as motor power, size and weight, and control electronics.

They constitute a significant portion of the vibration and noise generated by the transmission. Sidebands have influence on noise quality measures as well as having great potential to provide valuable clues regarding gear tooth combinations, phasing of planets, manufacturing errors like eccentricity, run out present in the gear set, planet pin position error, etc. [Read More](https://blog.portescap.com/experimental-approach-for-solving-side-band-noise-of-miniature-planetary-gearbox) Topics: [gearhead](https://blog.portescap.com/topic/gearhead), [side band noise](https://blog.portescap.com/topic/side-band-noise) ## [Delivering the Ultimate Motor for Craniotomy Hand Tools](https://blog.portescap.com/delivering-the-ultimate-craniotomy-hand-tool-with-the-highest-precision-accuracy-and-comfort) Posted by [Portescap](https://blog.portescap.com/author/portescap)   Sep 13, 2021 **Delivering the Ultimate Motor for Craniotomy Hand Tools ** Craniotomy hand tools are high speed drills used in neuro (skull) surgeries. These complex procedures require the ultimate in accuracy, precision and balancing. Even minor vibrations or jerks could impact the outcome of surgeries.
