The Noise Comparison Between Pendant Motor and Micro motor System

The first thing customer’s note when using a marathon micro motor for the first time is the noise level, they are quiet! We have customers who have smart jewelry showrooms with studios at the rear, quiet micro motor systems are a must to keep the pleasant atmosphere in the shop. Equally in the home this can be a major plus.

A Pendant Motor is often higher torque than a Micro motor

Torque is the amount of force put into rotation. Not all applications need the highest torque available. For Jeweler’s or Dental Technicians for example a Micro motor system will often have adequate torque. Wheels and burrs tend to be small and therefore need less torque.

For engineers, fabricators, sculptors etc. they may need a bit more grunt and higher torque to drive larger wheels and points.

Micro motors can offer higher speeds

Pendant Motors tend to be limited to 25,000 rpm (some more, some less), Micro motors however typically offer closer to 35,000 rpm. Some carbide burrs and cutters like to be run at higher speeds; small diameter burrs work well with the lower torque and high speeds.

This makes them a good option for delicate jobs like stone setting, precision engineering and dental technician work.

Are Pendant Drills Heavier Duty?

For fabrication, large sculpture, engine tuning, engineering etc. the best choice is normally a pendant motor. They are really built for slightly rougher treatment.

Certainly our LY128 system has proven over the years to be a sturdy workhorse with little going wrong with it.

However in precision engineering environments our Eneska Micro motor system really holds it’s own. They are very sturdy and can withstand long hours of use. For the user they are much more comfortable to use for prolonged periods.


Brushless Micro motor have noticeably less vibration. In a lot of industries now there are health and safety regulations on vibration. Micro motors tend to be the choice where this is a requirement. They are much more comfortable for operators to use for long shifts. For all users this is a plus point, the difference is very obvious.
