Servos for Aerospace Applications

Key Takeaways:

  • The K-Power brushless and DC-powered servo has a torque value of 15 Nm. and weighs 330g.
  • The GYEMS RMD-X10 servo brand has a brushless motor that can be powered by a DC power source.
  • The Rovmaker brand of servo has a peak torque value of 3.5 Nm, slightly below the required specification.

Introduction

The following research brief shows some examples of lightweight servos that are closest to the ideal servos described. We were not able to find examples of servos that met all of the given criteria.

K-Power Brushless Servo

GYEMS RMD-X10

  • The GYEMS RMD-X10 servo brand has a brushless motor that can be powered by a DC power source.
  • It has a maximum torque value of 50Nm.
  • The product weighs around 1.2 kg., slightly above the required weight.
  • It has an RPM speed of 150.
  • The rest of the product specifications can be found in this link.

Rovmaker T40 Servo

  • The Rovmaker brand of servo has a peak torque value of 3.5 Nm, slightly below the required specification.
  • It weighs 360 g. and has a dimension of 66 by 55.5 by 35.5 mm.
  • The rest of the product specifications can be found in this link.

Research Strategy

To find examples of servos that can meet the required specifications, we looked through reputable sources such as the website, product pages, and product brochures of popular manufacturers and distributors of servo motors such as Siemens, Sanyo, SAE, Crouzet, EBM, Schneider Electric, H2W Technologies, Ibex Engineering, SunSource, Nidec, Aerotech, and other similar companies. Based on this search approach, we were not able to find servos that possess all the attributes mentioned. We found many types of servos but the products only possess a few of the attributes mentioned. Most of the servos found that have high torques weigh more than 2.5 lbs.

We also looked through various industrial supplier directories such as Thomasnet, RS Online, Alibaba, Direct Industry, and other similar sites. We used the filters on those sites to find the servos that have the requested specifications. We then found many examples of servos but there were very few that met most of the specifications. We were not able to find servos that possess all the indicated specifications.

We also looked through engineering publications, aerospace websites, industrial websites, and other similar sites to obtain articles or reports that may describe some of the servo products used in the industry but we only found some general specifications. We were not abble to find specific details that can lead us to the right type of servos.
Based on our research results, we presented those servos that closely match the given specifications.
