Fast, reliable DC motors for ice-core drilling in the Antarctic.

Ice-core drilling is nothing new. But maxon motor developed a DC motor gear combination that can drill up to eight times faster than existing drilling, 600 metres below thick ice.

Conventional ice-core drilling takes a long time. The 3.4km deep hole at Dome Concordia in the Antarctic took five years to complete. 800,000 year old ice was retrieved which, up until now is the profoundest look into the history of the Earth’s core.

Using maxon motor DC technology, several small drill-sites of approximately 600 meters are bored to ascertain the correct position to deep-drill. The thickness of the ice and the geothermal heat indicate if it is worth drilling deeper to yield useful scientific results. A process that would previously take two months to complete, but now with maxon DC motors takes seven days.

The DC motor gearhead combination selected for this task was an off-the-shelf, maxon EC 45 250 Watt motor combined with a GP 52 planetary gearhead. Some modifications were made however the basis of the selection was the high power and high torque, with the ability to vary the speed of the motor at a constant torque. Most importantly, the DC motor had to fit into a very compact space within the drill and withstand extreme temperatures.
