The new maxon (Fall River, MA) EC-4pole 32 HD motor has been designed for extremely rough operating conditions, particularly applications in deep drilling. Deep drilling technology (called “downhole drilling” in the field of oil and gas exploration) makes it possible to recover oil and gas from depths of more than 2500 m. Features include:
• A 220 W power rating in air and, due to the much higher heat flow, 480 W in oil.
• Ambient temperature range of more than 200 °C and atmospheric pressures of up to 1700 bar.
• The ability to withstand vibrations of up to 25 grms as well as impacts of up to 1000 G (1000 times the acceleration due to gravity at the earth's surface).
• High efficiency (up to 89% in air, more than 80% in oil).
