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.

The phase out of an old DC motor and the realisation of power, weight and price advantages of new designs, widens customer device application areas.
The maxon 2260 series of brushed DC motors was for decades an industry standard, providing reliable high torque performance. Because of its quality and longevity it was not considered for replacement or design-out until they were informed via maxon motor’s discontinuation policy procedures of its pending obsolescence. The initial disappointment and concern was quickly turned to relief after maxon initiated application engineer contact to advise customers about the available replacement possibilities. The maxon DC 2260 motor featured a continuous power rating of 80W and 330mNm of torque from 60mm diameter and 126mm length. The motor had a mass of 1300g. The typical replacement motor for the 2260 is the maxon RE50. This new motor features a continuous power rating of 200W and 450mNm from a 50mm diameter and 108mm length. What’s more, there are higher speed capabilities, a 200g weight reduction and yes, it is less expensive. In one instance the performance increase has given a customer’s product increased versatility and higher sales. The typical response being “why didn’t we do this earlier?!”. maxon motor provide support through the products entire lifecycle and as motor technology advances the end applications evolve also.

Complex processing applications requiring human interaction require absolute precision to ensure operator safety. New zero backlash brushless DC servo gear motors with absolute encoder combinations supply the solution.
When a mineral processing company required an automation process involving high torque levels in close proximity to the machinery operator, new product thinking was required. The heavy equipment being moved generates considerable inertia that would need to hold under brake tension. Position control of the load requires encoder feedback on the brushless DC motor to compliment absolute encoder feedback on the load and zero backlash on the gearhead to ensure the unit is in the exact position that the control system thinks it is.
The solution pictured is the first assembled combination of a maxon 60mm 48V 400w brushless DC motor, 3 channel digital incremental encoder, 24V holding brake and 160:1 zero backlash gearhead. This new motor solution can hold a 400Nm load continuously and withstand shock loading on the output of up to 2200Nm. Speeds of up to 30rpm are capable from the unit and it is easily configured for use with servo amplifiers or position controllers having zero cogging or mechanical detents.
