The new 200°C / 100 G / -5,000 m / 1'700 bar drive systems from Maxon Motor Australia set new benchmarks,  proving they can operate in harsh ambient conditions as encountered deep underneath the earth's surface.

Dependable and efficient, the new EC 22 HD (Heavy Duty) standard motors have been designed to operate in extremely harsh conditions. Developed for the exceptionally high requirements in deep drilling technology, these electronically commutated motors EC 22 HD resist even most extreme conditions in which "normal" drives call it quits.

The different variants of the EC 22 HD drive systems are designed for operation in air or submerged in oil (flooded in hydraulic fluid). Their assigned power rating depends on the surrounding medium and averages to 80 Watts in air and, due to remarkably higher heat dissipation, 240 Watts in oil. They are designed to cope with ambient temperatures of more than 200°C (390°F) and atmospheric pressures of up to 1,700 bar (25,000 psi).

Further requirements of the 22 mm diameter drive systems are the capability to withstand vibration of up to 25 grms as well as impulse and impact of up to 100 G, that is 100 times gravitational acceleration.

The motors feature high efficiency (in air up to 88%, in oil more than 70%) and therefore offer the best prerequisites for battery-operated applications. With their detent-free running characteristics, they possess outstanding regulation behavior and are especially suitable for high-precision positioning tasks, even at low speed.
